Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail and completely with reference to the following embodiments and accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
One of the functions of the remote sensing satellite is earth observation, namely, shooting the earth surface on the satellite orbit to obtain an observation picture and an image video. In real life, a large number of so-called satellite images are obtained from the above-mentioned earth observation. Traditional earth observation generally relies on manual, i.e. manual control of the shooting by the satellites. In the remote sensing satellite with higher automation degree, automatic ground shooting can be realized; that is, the control is performed by a control program so that the satellite performs shooting at a specific position or at a specific cycle.
However, in the above-described system, due to the limitation of the satellite-to-ground communication capability, the staff at the ground station cannot freely control the shooting of the satellite and obtain the shooting data in real time, thereby realizing the observation function conforming to the concept of "human in the loop".
In view of the above, the present invention provides a communication method for a satellite. Referring to fig. 1, a specific embodiment of a communication method for a satellite according to the present invention is shown.
It is well known that a satellite vehicle orbits the earth in a fixed orbit, and that a ground station capable of communicating with the satellite is located at a fixed position on the earth's surface. That is, based on the principle of linear propagation of electromagnetic waves, a satellite can communicate with a ground station only when it passes through a certain range above the ground station. When the satellite falls below the horizon, communication cannot be performed. This communicable range is also referred to as the satellite to ground station communication window. The visible communication window is intended and limited.
Within the communication window, the distance between the satellite and the ground station is constantly changing. First from far to near, then from near to far. During which the satellite will use radio waves to effect communication with the ground station. The communication of radio waves has the following characteristics: if the frequency is higher, the carried information code rate is higher, the data volume capable of being carried is larger, but the communication distance is closer; conversely, if the frequency is lower, the carried information code rate is lower, the data volume that can be carried is smaller, but the communication distance is longer.
That is, the communication between the satellite and the ground station always faces the problem that the information code rate and the communication distance are not compatible. If a frequency band with a high code rate is used for communication, the communication distance is limited, so that when a satellite just enters a communication window and is about to leave the communication window, communication cannot be performed due to too long distance, the communication window is not fully utilized, and the communication window is artificially reduced. If a frequency band with a low code rate is used for communication, the satellite can only keep low-code-rate communication within a short distance range, and the communication efficiency cannot be fully improved. This is also the main reason why the observation function conforming to the concept of "man in the loop" cannot be realized due to the limitation of satellite-to-ground communication capability as described above.
In this embodiment, the communication mode is improved, and thus, an observation function conforming to the concept of "human presence loop" is realized. The method comprises the following steps:
In the present embodiment, in order to improve the communication efficiency to the greatest extent, at least two communication connections, i.e., a first communication connection and a second communication connection, are established between the satellite and the ground station. The first communication connection adopts a fixed communication frequency band and is used for keeping the satellite and the ground station in contact in real time in a communication window. The communication frequency band of the second communication connection is adjustable, and the second communication connection is used for actually transmitting data from the satellite to the ground station, so that the data return to the ground can be efficiently realized as far as possible by the satellite in a communication window.
Specifically, the ground station may first establish a first communication connection with the satellite, and determine a preset first frequency band as a communication frequency band of the first communication connection. The first frequency band is a low frequency band and therefore has a communication distance that is long enough to maintain communication throughout the range of distances from the satellite entering the communication window to the satellite leaving the communication window. That is, when the satellite enters the communication window, the first communication connection may be established directly, but not disconnected until the satellite leaves the communication window. However, since the information code rate supported by the first communication connection is low, the actual data transmission is not performed during the use period in this embodiment; but merely to maintain a communication connection or to perform some simple communication interaction.
A second frequency band may then be determined based on the first communication connection. In particular, the range of the satellite may be determined based on the first communication connection; the second frequency band is determined according to the distance of the satellite.
After the first communication connection is established, ranging to the satellite can be performed according to the first communication connection, which is well known in the art and will not be described herein. Of course, since the distance of the satellite from the ground station is constantly changing, the first communication connection should be utilized to determine the distance of the satellite in real time within the communication window.
And the current second frequency band can be determined according to the distance from the satellite to the ground station. That is, the transmission distance is not less than the distance from the satellite to the ground station, and the frequency band with the highest frequency is determined as the second frequency band. That is, the frequency band having the highest frequency that can support the current distance is used as the second frequency band. The second frequency band therefore has the following characteristics: the communication distance can ensure that the satellite can communicate with the ground station at present, and the frequency can be as high as possible, thereby maximizing the communication efficiency. The ground station may thus establish a second communication connection with the satellite and determine the second frequency band as the communication frequency band of the second communication connection.
The first communication connection and the second communication connection may be established simultaneously when the satellite enters the communication window. At this time, since the satellite is far away, the first frequency band and the second frequency band may be the same frequency band. That is, the second frequency band has a lower frequency at this time, but the second communication connection can realize a communication function, and a communication window is utilized as fully as possible.
As the satellite moves, the distance between the satellite and the ground station is closer and closer, so that when the distance is smaller than the communication distance of a frequency band with a higher frequency, the frequency band with the higher frequency can be determined as the second frequency band, that is, the frequency of the second communication connection is increased. After the second communication connection is replaced by the higher-frequency second frequency band, the communication efficiency is further improved, and data can be transmitted back to the ground station at a higher code rate, so that more functions based on efficient communication are realized.
By analogy, the second frequency band used by the second communication connection may be gradually increased in frequency until the satellite is closest to the ground station. Then, as the distance between the satellite and the ground station becomes longer and longer, the frequency of the second frequency band is gradually decreased according to the reverse principle until the satellite leaves the communication window.
In the process that the satellite moves from far to near and from near to far, the second frequency band synchronously realizes the change from low frequency to high frequency and then from high frequency to low frequency. Therefore, the satellite can be ensured to be communicated with the ground station through the second communication connection all the time in the communication window, and waste of the communication window is avoided. And under the condition of meeting the communication distance, the satellite can adopt the highest frequency band as possible to carry out communication, so that the communication efficiency is highest within the time and space range covered by the communication window, namely the total amount of returned data is highest. The problem of low communication efficiency caused by the fact that the satellite still uses low-frequency band communication in a short distance is solved.
102, sending a control instruction to a satellite by utilizing the first communication connection or the second communication connection; so that the satellite executes observation operation according to the control instruction and obtains corresponding observation data.
According to the "people on the loop" concept, the ground station can send control commands to the satellite within the communication window. Since the amount of data involved in the control command is small, communication can be theoretically achieved by either the first communication connection or the second communication connection. This is not limited in this embodiment. After the satellite receives the control command, the control command can be executed, the observation action required by the staff is realized, and the corresponding observation data is acquired, so that the observation requirement of the staff is met.
The second communication connection is used for actual data communication between the satellite and the ground station, i.e. for completing the return of the satellite observation data to the ground station. Since the frequency of the currently used frequency band of the second communication connection is different, and the communication efficiency is different, the return mode of the observation data may also be different. In this embodiment, details are not described herein, and any form of observation data feedback can be combined with the overall technical solution of this embodiment.
According to the technical scheme, the beneficial effects of the embodiment are as follows: the first communication connection and the second communication connection are established with the satellite, and the first communication connection and the second communication connection are matched to realize communication, so that the satellite can always communicate with the ground station in a communication window, and the waste of the communication window is avoided; meanwhile, the highest possible frequency band can be used for communication, and the communication efficiency is highest; the problem of low communication efficiency caused by the fact that the satellite still uses low-frequency band communication in a short distance is solved.
Fig. 1 shows only a basic embodiment of the method of the present invention, and based on this, certain optimization and expansion can be performed, and other preferred embodiments of the method can also be obtained.
Fig. 2 shows another embodiment of a communication method for a satellite according to the present invention. The present embodiment is further described on the basis of the foregoing embodiments. In this embodiment, the method includes the steps of:
And step 203, establishing a second communication connection with the satellite, and determining the second frequency band as the communication frequency band of the second communication connection.
In the above steps 201 to 203, it is determined to establish the first communication connection and the second communication connection in a manner consistent with the embodiment shown in fig. 1, and the first communication connection is used for ranging, so as to determine the second frequency band of the second communication connection in real time. The description is not repeated here.
In this embodiment, the first communication connection may be selected to send the control instruction to the satellite, so that the satellite executes an observation operation to obtain observation data. Specifically, the observation instruction may be a photographing observation instruction, and/or a camera motion control instruction. According to the photographic observation instruction, the satellite can photograph the earth surface to obtain an observation image as observation data. According to the shooting observation instruction, the satellite can shoot videos on the earth surface to obtain observation videos serving as observation data. According to the camera action control instruction, the angle and the posture of the visible light camera carried by the satellite can be adjusted, so that the shooting of a specific direction and a specific target is realized. Therefore, through the control instruction, the staff can flexibly control the satellite to execute the required observation action.
In this embodiment, the second communication connection is still used for actual data communication transmission. It is known from the foregoing that the frequency of the second frequency band of the second communication connection affects the communication efficiency. The communication efficiency further determines whether certain functions in the communication process are conditionally implemented.
For example, when the frequency of the second frequency band is low, only some low-density data can be transmitted back due to limited communication efficiency, and the transmission back of a large amount of data cannot be completed in real time. The feedback mode at this time may be an "image mode", that is, only the observation image can be fed back in real time. That is, when the staff member makes the satellite collect the observation image through the control command, the observation image can be transmitted back in real time for the staff member to browse.
After the frequency of the second frequency band is increased, the communication efficiency is improved, so that the return of a large amount of data can be completed in real time. At this time, the return mode may be a "video mode", that is, not only the observation image but also the observation video may be returned in real time. That is, when the staff makes the satellite collect the observation video through the control command, the observation video can be transmitted back in real time for the staff to browse, thereby embodying the function similar to 'live broadcast' and also conforming to the concept of 'human in loop'.
