Problems solved by technology

[0007] In the above scheme, the present invention adds a communication receipt processing flow in the communication process to Beidou RD, and changes the open-loop communication transmission mode of the existing Beidou RD communication into a closed-loop communication transmission mode, which can effectively solve the problems in the existing communication process. The problems of unreliable information delivery or undetectable transmission status lead to the failure of messages, so as to realize the observability of Beidou RD communication status and improve the reliability of Beidou RD communication

Embodiment

[0031] The present invention realizes the return receipt method of Beidou RD communication by judging the receiving state of receiving terminal B and generating a corresponding return receipt message and sending it to sending terminal A, so as to realize the closed-loop communication transmission mode of Beidou RD communication.

[0032] The present invention realizes the flow chart of the return receipt method of Beidou RD communication as figure 2 Shown, the inventive method specifically comprises the following steps:

[0033] In the first step, the sending terminal A sends the communication message 1;

[0034] In the second step, the communication message 1 is forwarded to the receiving terminal B by the Beidou RD communication satellite, and at the same time, the Beidou RD communication satellite sends the application for sending the short message of the communication message 1 to the Beidou service platform in the form of UDP data packets through the dedicated line of th...

Abstract

The invention provides a receipt method for achieving big dipper RD communication. According to the method, a first communication telegraph text of a sending terminal is compared with a second communication telegraph text of a receiving terminal, a generated receipt telegraph text is sent to the sending terminal, and a closed-loop communication transmission mode of big dipper RD communication is achieved. According to the receipt method for achieving the big dipper RD communication, a communication receipt processing procedure is added in the big dipper RD communication process, an existing open-loop communication transmission mode of big dipper RD communication is changed into the closed-loop communication transmission mode, the problem that information cannot be reliably sent or the transmission state cannot be detected in an existing communication process can be effectively solved, observability of the big dipper RD communication state is achieved, reliability of big dipper RD communication is improved, and the method has a great and practical significant in promoting the big dipper civil use progress.

Description

technical field [0001] The invention relates to the field of satellite navigation and communication, and more specifically, relates to a return receipt method for realizing Beidou RD communication. Background technique [0002] The Beidou satellite navigation system is a regional satellite navigation system independently developed by my country. The system covers the entire territory of my country and surrounding countries. The whole system consists of three parts: sky satellites, ground control stations and user application terminals. The user application terminal has the functions of positioning, navigation and short message data communication, and has a wide range of applications in the fields of positioning, navigation and communication. [0003] Beidou RD short message communication is a characteristic function of Beidou satellite navigation system. Beidou RD communication is a satellite communication function independently developed by Beidou satellite navigation syste...
