A realization method of Beidou rd multi-channel communication

Abstract

The invention provides an implementation method of compass RD multichannel communication. The method comprises the following steps: arranging and placing N compass RD communicators, wherein each compass RD communicator corresponds to a transceiving channel; then detecting the idle states of the transceiving channels of the arranged and placed compass RD communicators so as to select M idle compass RD communicators capable of communicating; then controlling M compass RD communicators for communication to realize information transmission of M user application terminals through the transceiving channels of the M compass RD communicators in one transmission frequency. According to the method, the information transmission of a plurality of user application terminals can be realized in one transmission frequency, and the limitation that only one short message can be transmitted in one transmission frequency is broken through; meanwhile, mutual signal interference among the compass RD communicators can be shielded during the multichannel communication, and thus the stability and efficiency of the compass RD communicators during the multichannel communication are improved.

Description

technical field [0001] The invention relates to the field of satellite navigation and communication, and more specifically, to a method for realizing Beidou RD communication. Background technique [0002] The Beidou satellite navigation system is a global satellite navigation system independently developed by my country. The whole system consists of three parts: sky satellites, ground control stations and user application terminals. The Beidou RD short message communication is a characteristic function of the Beidou satellite navigation system. The Beidou RD communication is jointly completed by the space satellite, the ground control main station, and the ground Beidou terminal. It is initiated by the ground terminal, controlled by the main station, and relayed by the space satellite. [0003] Among them, the user application terminal has functions such as positioning and short message data communication. At present, in real scenarios, the command center sends Beidou shor...

Problems solved by technology

[0008] When multiple Beidou RD communicators send messages at the same time, due to the electromagnetic interference of adjacent Beidou RD communicators, it is easy to cause mutual interference between Beidou RD communicators during the sending process, resulting in garbled codes and packet loss, resulting in The Beidou RD communicator has poor stability and high error rate when realizing multi-channel communication, which greatly affects the communication connection between user application terminals and Beidou satellite signals
