Fig. 1 is a schematic block diagram of a wireless communication system according to an embodiment of the present invention.
As shown in fig. 1, the wireless communication system according to the present embodiment includes: unmanned aerial vehicle equipment 101, RTK base station equipment 102, RTK client 103 and server 104. The RTK base station device 102 sends the first location information to the server 104. The drone device 101 sends the second location information to the server 104 via the RTK client 103.

The position information may be various navigation information such as GPS information, GLONASS (GLONASS) information, and beidou navigation information.
Fig. 2 is an overall schematic flowchart of the wireless communication between the drone device and the RTK device according to the embodiment of the present invention.
As shown in fig. 2, when the drone device 101 performs wireless communication with the RTK base station device 102, the RTK base station device 102 transmits first position information to the server 104 (step S201), the drone device 101 transmits second position information to the server 104 via the RTK client 103 (step S202), the server 104 performs difference calculation using the first position information and the second position information (step S203), and transmits the calculated third position information to the drone device 101 via the RTK client 103 (step S204).
It can be understood by those skilled in the art that, in the above communication process, there is no precedence relationship between step S201 and step S202, and the two steps may be executed successively or simultaneously.
According to the invention, the unmanned aerial vehicle device 101 can effectively utilize the RTK base station device 102 to perform high-precision navigation through the RTK client 103 so as to meet the working requirements of the unmanned aerial vehicle. In addition, through combining network RTK technique and unmanned aerial vehicle equipment, management RTK equipment that can be effective, convenient makes it provide the geographical navigation positioning information of high accuracy for unmanned aerial vehicle equipment.
In the present embodiment, when the RTK base station device leaves the factory, a company may implant a certificate of x.509 format for company authentication, which may be one-certificate-for-one, multiple-certificate-for-one, or multiple-certificate-for-one, and be maintained by the company or a third-party certificate issuing authority. And securely hold the certificate, for example and without limitation to the trustzone scheme of 1860 chips.
Fig. 3 is a schematic flowchart of authentication and communication of an RTK base station device according to an embodiment of the present invention. In an embodiment, when the RTK base station device 102 operates, a Secure communication link is first established through a Secure Sockets Layer (SSL) protocol, and a bidirectional SSL protocol verification scheme is adopted during the SSL protocol handshake of the server to verify the validity of the RTK base station device 102 and prevent a counterfeit RTK base station device from transmitting data. After the authentication is passed, the RTK base station device transmits the differential data for navigation to the server 104 by using an Ntrip Protocol (network Transport of RTCM via Internet Protocol, Protocol for performing RTCM network transmission via the Internet). The verification scheme is not limited to the above-described scheme, and any applicable verification scheme may be employed.
That is, before the RTK base station apparatus 102 transmits the position information (first position information) to the server 104, the RTK base station apparatus 102 and the server 104 establish the SSL protocol link through bidirectional SSL protocol verification. After the SSL protocol link is successfully established, the RTK base station device 102 sends the position information (first position information) to the server 104 through the Ntrip protocol.
In some embodiments, the usage rights of the RTK client need to be managed.

In the present embodiment, as a local link, taking an SDR (Software defined Radio) link as an example for explanation, the drone device 101 may establish a connection with the RTK client 103 through the SDR link. However, the local link is not limited to the SDR link, and may be a wifi (Wireless Fidelity) link, a Bluetooth (Bluetooth) link, or the like. The RTK client 103 authenticates the server 104 through the server-side certificate, and the server authenticates the RTK client 103 through the Ntrip protocol handshake.
After establishing the connection, the RTK client 103 provides the user name and account number to the server 104 through Ntrip protocol handshake. After the authentication is passed, the position information (second position information) is transmitted by using the TCP connection, and if the server fails to verify, the server disconnects the TCP connection.
That is, in one embodiment, the drone device 101 sends the position information (second position information) over the local link to the RTK client 103, which the RTK client 103 sends to the server 104 using a TCP connection.
