Detailed Description

In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.

Example 1

Referring to fig. 1, a flowchart illustrating steps of an embodiment 1 of a method for querying satellite real-time orbit information according to the present application is shown, which may specifically include the following steps:

step 101, acquiring a plurality of first satellite transmitting information of a target satellite through a first information source.

The satellite launch information may include at least one of a launch time of the satellite, a launch location, launch vehicle information (e.g., launch vehicle name, model number, etc.), a satellite name, etc.

In this embodiment of the application, the first information source may be a news webpage that issues satellite information or satellite transmission information that is acquired by a user through other ways. Accordingly, the step 101 may include: capturing a plurality of first satellite transmitting information from a news webpage for releasing satellite information; or, receiving the first satellite transmission information input through the set entrance.

Any suitable means for acquiring satellite transmission information from the news webpage can be adopted, and the method is not limited in the application, such as regular matching or a keyword capturing mode.

Step 102, searching for the first satellite identification of the target satellite from the second information source based on the at least one first satellite transmission information.

The satellite identifier is used to uniquely identify the satellite, and the first satellite identifier may be an international satellite identifier COSPAR ID, NORAD ID, or an ID named by other standards.

COSPAR ID, among others, is referred to in the united states as NSSDC ID, which is an international convention for naming and identifying satellites. Wherein COSPAR is english abbreviation of international Committee on Space Research. COSPAR ID consists of two rows of numbers and one row of letters. The first row of numbers is the year of transmission of the satellite, the second row of numbers is the global transmission order of the satellite in the year of transmission, and the letters following the second row of numbers are used to identify each part for use when separating out a plurality of parts in the transmission task. This identification system is generally referred to as COSPAR nomenclature.

The following table illustrates the usage and meaning of COSPAR ID by taking the aircraft such as the sptney 1, the eastern red first, the habo space telescope, the shenzhou spaceship, etc. as examples.

The norrad satellite number is also called NASA number, SCC number, and is a satellite number specifically established by norrad (North American aviation mission force feedback Command, united headquarters for North america), and each spacecraft is assigned a unique norrad satellite number. The NORAD satellite number consists of a five digit satellite identification code, each digit having a specific meaning.

The following table clearly identifies the incremental representation of NORAD on the total number of satellites that are heavily stressed by the different numbers of the aircraft from COSPAR on the time, sequence and manner of satellite launch.

The second information source may be satellite tracking software or an information source such as a satellite tracking station providing a satellite information query, supporting query of other related information by transmitting information through one or more satellites, and the query result provides at least a first satellite identifier of the satellite and may also provide other related information of the satellite.

When the satellite transmitting information is acquired through the second information source, various suitable methods such as directly accessing the satellite tracking software or the satellite tracking station, accessing the server corresponding to the satellite tracking software or the satellite tracking station, or accessing an API application programming interface provided by the server may be adopted.

The satellite tracking software can be Orbitron, and the Orbitron can display the relative position of the satellite and the earth at any moment in real time or in a simulation mode. The main functions include: 1) two thousand satellites can be tracked simultaneously; 2) full screen display and presentation mode display; 3) advanced over-the-top time prediction and iridium track search are achieved; 4) the internal clock of the computer can be corrected through the NTP server; 5) ephemeris data can be updated through the internet (support for ZIP compression format); 6) can control radio stations and satellite antenna trackers.

As shown in fig. 4, which is a main interface of Orbitron, various settings can be selected in the lower tab page, and a specific satellite object can be set by checking on the right side, so that more than 2000 satellites and space stations can be tracked.

The satellite tracking station can be an official inquiry station provided by each international aerospace platform, and can also be some inquiry stations supported by fan groups or individuals. The following table illustrates a plurality of sites in which information such as web addresses, descriptions, organizations/organizations to which the sites belong, countries, etc. are given for each query site. Wherein, NASA (national aerospace agency) is an official query site, and can provide diversified queries based on COSPAR ID or NORAD ID; the "position of artificial star of JavaScript で in japan" is a network supported by the hobbyist group, and as shown in fig. 5, the satellite tracking site is a schematic view of the satellite tracking site, and information related to the orbit height, orientation, and the like of the "tiangong first" space laboratory in china can be clearly viewed in real time on the site.

Since there may be an error in the satellite transmission information acquired from the first information source such as a news web page, even if the transmission time is erroneous, the range of the transmission time can be estimated from the erroneous transmission time, and a search can be performed based on the estimated range. Therefore, the embodiment of the present application may preferably search for the first satellite identifier in the second information source based on the transmission time.

Since there may also be errors in the transmission time, for example, errors of several days, the first satellite identification may not be found by performing a search based on the satellite transmission time. In this case, a time interval to which the transmission time belongs may be defined, for example, two days before and after the transmission time, and the first satellite identifier may be searched for in the second information source according to the time interval. It is also possible to find all satellites transmitted in the year by the transmitting country of the target satellite. And extracting the current satellite closest to the emission time of the target satellite from the comparison result, determining the current satellite as the target satellite, and extracting the satellite identification of the current satellite as the first satellite identification of the target satellite. During specific comparison, satellites in the whole year can be arranged according to a time sequence and compared one by one in sequence.

Step 103, searching the real-time orbit information of the target satellite from a third information source based on the first satellite identification.

The third information source can be satellite tracking software or an information source such as a satellite tracking station and the like for providing satellite information query, and supports query of satellite real-time orbit information through satellite identification.

When the third information source is used to obtain the real-time orbit information of the satellite, various suitable methods such as directly accessing the satellite tracking software or the satellite tracking station, accessing the server corresponding to the satellite tracking software or the satellite tracking station, or accessing the API application programming interface provided by the server may be adopted.

The embodiment of the application can be used as a functional plug-in to be deployed on a browser capable of browsing a satellite tracking site, the user can automatically or through setting operation to trigger query of real-time orbit information when browsing a news webpage, and the functional plug-in can also be deployed on satellite tracking software, or can be used as a satellite tracking site or a functional item of the browser to perform query of the real-time orbit information according to transmitting information input by the user.

Example 2

Referring to fig. 2, a flowchart illustrating steps of embodiment 2 of a method for querying satellite real-time orbit information according to the present application is shown, which may specifically include the following steps:

step 201, acquiring a plurality of first satellite transmitting information of a target satellite through a first information source.

Step 202, searching for the first satellite identification of the target satellite from the second information source based on the at least one first satellite transmission information.

Step 203, the first satellite identification is verified for authenticity based on the official website transmitted by the satellite.

After the first satellite identification is acquired, it may also be verified to ensure the accuracy of the subsequently acquired orbit information. Specifically, the first satellite identifier may be searched for on an official website transmitted by a satellite, and if the first satellite identifier is found, it is determined that the first satellite identifier really exists. Specifically, the first satellite identifier may be queried by accessing the website, or accessing a server or an API interface corresponding to the website.

Preferably, the official website for the corresponding verification for the COSPAR ID may be the official website of the National Aeronautics and Space Administration (NASA) with the corresponding website http:// nsdc.gsfc.nasa.gov/nmc/spactraftquery.jsp, which provides COSPAR ID retrieval, the documenting work of which is managed by the national space science data center under the jurisdiction of the national aeronautics and space administration.

Step 204, at least one second satellite transmission information is searched for in the official website based on the first satellite identification.

Further, the satellite transmission information recorded by the official website can be searched on the official website based on the first satellite identifier so as to be compared with the satellite transmission information acquired based on the first information source.

The second satellite launching information may include a launching time and a launching place of the satellite, and may further include at least one of carrier rocket information (such as a carrier rocket name, a model number, etc.) of the satellite, a satellite name, and the like. The transmitting location may be a specific geographic location, or may be a name of a transmitting field or a transmitting field number.

Step 205, correcting the first satellite transmission information according to the at least one second satellite transmission information.

Since the satellite transmission information published by the official website is accurate information, and the information published by the first information source such as a news webpage and the like often has errors, the first satellite transmission information can be corrected by adopting the second satellite transmission information acquired from the official website. Specifically, the second satellite transmission information corresponding to the same information classification can be directly replaced by the corresponding first satellite transmission information, or comparison can be performed first, and replacement is performed according to the inconsistent situation.

The information transmitted by the first satellite is identical with the information transmitted by the second satellite, and the two information may be completely identical or may be expressed to be inconsistent, but the actual meanings are identical. Therefore, a further determination is required for the case where the expressions do not match. Specifically, whether the first satellite transmission information and the second satellite transmission information corresponding to the same information category are consistent or not may be determined based on network search. For example, the launching Site of the satellite based on news web page crawling is within asia, while the launching Site based on NASA query adopts the number of a launching field (Launch Site), denoted as Do LC-370/13, and through network search query, the launching Site known as simply "Do" is Yasniy Site, dombarovski Air Base, orenburskaya Oblast', Russia, i.e., the dobasofsky launching Base of Russia, within asia near orleburg, so that the launching Site of the NASA query is known to coincide with the "within asia" launching Site vaguely described in the news web page.

The satellite transmission information acquired through the first information source such as the news webpage is corrected based on the satellite transmission information searched by the official website, so that the user can be ensured to acquire accurate satellite information.

Step 206, searching real-time orbit information of the target satellite from a third information source based on the first satellite identification.

Step 207, parsing the real-time track information into readable information according to a standard format.

Because the track information contains a large amount of data, the track information is usually expressed by adopting a certain standard format, and the track information can be analyzed according to the standard format in order to be readable and understandable.

For example, orbit information may be represented as Two lines of orbit data (TLE), also known as satellite ephemeris, which is an expression used to describe the position and velocity of a space vehicle, which data is available from public sources on the internet. The structure of the satellite ephemeris is two lines, each line is 69 characters, including 0-9, A-Z (capitalization), space, point and sign, and other characters are meaningless. According to the standard format definition of TLE, referring to fig. 6, the interpretation manner of the first row and the second row of data is shown in fig. 6, where fig. 6 is a schematic diagram of interpretation of a satellite ephemeris format according to an embodiment of the present application.

The latest TLE data of "Tiangong No. (Tiangong 1) inquired on 11

days

12 and 12 months 2015 is taken as an example for explanation, and the data is as follows:

1 37820U 11053A 15345.10877468.00028095 00000-0 23484-3 0 999 7

2 37820 42.7644 293.8434 0015761 176.4316 245.3790 15.69284487241045

referring to the international standard TLE format resolution, the following table shows:

wherein, the date is 15345.10877468 using currently acquired TLE data, which is JULIAN DAY (JULIAN DAY), i.e. 345.10877468 DAYs from 1/2015, and is converted as follows:

345.10877468days-345＝0.10877468days

0.10877468days x 24hours/day＝2.6106hours(Hours＝2)

2.6106hours-2＝0.6106hours

0.6106hours x 60minutes/hour＝36.636minutes(Minutes＝36)

36.636-36＝0.636minutes

0.636minutes x 60seconds/minute＝38.16seconds(Seconds＝38.16)

i.e., 345 days, 2 hours, 36 minutes, 38.16 seconds, i.e., converted to a specific date, 12 months, 11 days, 02:36:38, which is the UTC (UTC: Universal Time Coordinated) Universal coordination Time, which, like Greenwich Mean Time (GMT: Greenwich Mean Time, is the same as the local Time in London, UK.

Further, for the analysis result, the current time zone can be obtained, and time conversion is performed according to the current time zone, so that the user can conveniently check the time. For example, if converting to Beijing time, a time difference (8 hours) at Beijing needs to be added, i.e., 10:36:38 time.

In the embodiment of the application, preferably, the two lines of track data can be retrieved from a United states celebratk website, the website address is http:// celebratk. com/NORAD/elements/, the website provides the latest download of two lines of TLE data, and the data source is real and reliable; or a website http:// www.n2yo.com/query created at the U.S. agency itpro star, which provides data tracking such as the orbit of up to 17385 spacecraft; or a web site query created by a group of fans or an individual, such as the 3D real-time tracking satellite orbit site https:// in-the-sky.org/satmap, php, established by Dominic Ford, Cambridge, UK.

And 208, extracting at least one of the first satellite transmitting information and the analyzed real-time orbit information of the target satellite, and displaying the information at the associated position of the first information source.

The method and the device can also feed back the acquired satellite transmitting information, the real-time orbit information, the first satellite identification and the like to the associated position of the first information source for displaying, for example, to a certain position of a news webpage, so that a user can acquire the satellite orbit information in real time when browsing news.

In this embodiment of the application, preferably, before the searching for the real-time orbit information of the target satellite from the third information source based on the first satellite identifier, the method may further include: and searching a second satellite identification in a fourth information source based on the first satellite identification and/or at least one first satellite transmission information.

The first satellite identifier and the second satellite identifier may be COSPAR ID (international satellite identifier), NORAD ID, or other standard named IDs.

The fourth information source may be satellite tracking software or an information source such as a satellite tracking station that provides a satellite information query, in which a first satellite identifier and a second satellite identifier are recorded, and it is supported to query one satellite identifier by using the other satellite identifier. When the satellite identifier is obtained through the fourth information source, various suitable methods such as directly accessing the satellite tracking software or the satellite tracking station, accessing the server corresponding to the satellite tracking software or the satellite tracking station, or accessing the API application programming interface provided by the server may be adopted.

Preferably, a Satellite tracking station http:// www.amsat.org/status/index.php created by Radio service Satellite alliance (Radio Amateur Satellite Corporation) can be queried, the station supports query of NORAD ID based on COSPAR ID, and information such as Satellite launching time, orbit height, carrier rocket model number and the like can be queried, and the information can also be provided for users.

Correspondingly, preferably, the third information source further supports the query of the orbit information through the second satellite identifier and the first satellite transmission information, and the step 206 may specifically include: and searching the real-time orbit information of the target satellite from a third information source based on at least one of the first satellite identification, the second satellite identification and the first satellite transmission information.

In order to make the application better understood by those skilled in the art, the application is described below by way of a specific example. Fig. 7 is a schematic diagram of an inquiry process of satellite real-time orbit information in an example of the present application, which may specifically include the following steps:

Step 1: the satellite data mentioned in the news and open-report reports are read.

Step 2: extracting 4 parts of main information from news: time of launch, place of launch, launch vehicle, satellite name.

And step 3: judging authenticity: inquiring and checking the transmitting time and the transmitting place, specifically, inquiring and judging by accessing an NASA database, and executing a corresponding error correction mechanism.

And 4, step 4: checking validity: depth query and validation 4 aspects of information: NORAD ID, COSPAR ID, launch field, launch vehicle.

And 5: and (3) acquiring practicability: TLE star orbit data are obtained, and deep data mining is carried out.

To express the patent scheme more clearly, a query implementation example based on the scheme is listed as follows, which specifically includes:

1. refer to satellite data mentioned in open news reports.

Randomly extracting news about successful transmission of a certain satellite, which is published on the internet, specifically as follows:

reference message network 3 month 26 days report: on 26 months of korea, 26 days of the survey, the multifunctional utility satellite "ali No. 3A" was successfully launched on asian birch, and smoothly entered the predetermined orbit. By now, the satellite operates all the way normally, which means that the satellite transmission is successful satisfactorily. In the future, korea is expected to have the capability of performing regional observation in part of the day and night and all the weather.

2. Extracting 4 parts of main information from news: time of launch, place of launch, launch vehicle, satellite name.

4 parts of the main information are extracted from news reports: time of launch, place of launch, launch vehicle, satellite name, namely:

[ emission time ]: day 26 of 3 months, which is 2015 news, so it is 2015, day 26 of 3 months.

[ emission site ]: in Asia Si

[ Carrier rocket ]: is free of

[ satellite name ]: alilang No. 3A

The extracted data can find that all key data to be known can not be acquired in each news, and how to ensure that correct information data is acquired subsequently is also the problem to be solved by the application.

3. Judging authenticity: the query confirms the time of transmission (corresponding to the COSPAR ID) and the place of transmission.

According to the date of transmission mentioned in the above news, any satellite inquiry site is visited first, for example, NASA visits day 3 and 26, and as a result, no data is found on that day. Then, the transmitted satellite list is searched for a plurality of days before and after, the name of the satellite which is transmitted on the day of 25 days in 3 months is ' KOMPSat 3A ', and the COSPAR ID is 2015-014A '. Returning to the national aeronautics and astronautics administration (NASA) official network to confirm whether the number is true, and confirming OK according to the query results shown in the table below.

Spacecraft Name	NSSDC ID (i.e., COSPAR ID)	Launch Date
			Kompsat 3A	2015-014A	2015-3-25

According to the obtained COSPAR ID data, the launching site is locked to Do LC-370/13 through a satellite inquiry site, as shown in the following table:

through network search, the launching site of the ' Do ' is determined to be Yasniy site, Dombarvsky Air Base, Orenburgskaya Obblast ', Russia, which is a Dombarvestky (Dombarvsky) launching site in Russia, and the satellite launching site is transformed from an intercontinental ballistic missile site and belongs to a 6956 Air force site in Russia. Up to now, it has been conformed to the emission position "within asian" described ambiguously in the news, and it has also been proved that the emission time of 26 days at 3 months mentioned in "news report of korean news" cited in the domestic news article is wrong, and should be 25 days at 3 months. It follows that news stories are not necessarily accurate, but may be misleading. In order to eliminate such situations, the error correction mechanism in the query of the present application is to firstly confirm the transmission time, that is, to obtain the correct COSPAR ID, and then to correct the information by matching the transmission location.

From the above table, the source of the name of the satellite can be seen, wherein KOMPSat 3A (arirag 3A) is Arirang 3A, which does not necessarily appear in the query result, and the satellite in the news report can be determined to be currently queried according to the name.

4. Checking validity: depth query and validation 4 aspects of information: NORAD ID, COSPAR ID, launch field, launch vehicle.

Through the confirmed COSPAR ID and launching field information, deep information such as NORAD ID, satellite launching duration, orbit altitude, carrier rocket model and the like can be obtained through deep query, and can be used for further display, as shown below:

NORAD ID：40536

COSPAR ID：2015-014A

Perigee：526.6km

Apogee：546.5km

Inclination：97.5°
