Abstract

The invention discloses a Beidou navigation synchronization communication system. The system comprises two independent antenna modules used for independently receiving navigation messages of Beidou satellites, an analyzing module which is connected with the two antenna modules and is used for analyzing the received navigation messages of the Beidou satellites to acquire corresponding satellite ephemeris, clock signals and correction parameters, a control module which is connected with the analyzing module and is used for generating the navigation information, a feedback module which is connected with the control module and is used for carrying feedback connection for the navigation information generated by the control module, and an output module which is connected with the control module and is used for outputting the navigation information after correction. The invention further discloses a communication method of the Beidou navigation synchronization communication system. The Beidou navigation synchronization communication system is advantaged in that disadvantages in the prior art are ameliorated, and accuracy of navigation signals is improved.

Description

technical field [0001] The invention relates to the technical field of Beidou navigation, in particular to a Beidou navigation synchronization communication system and a communication method thereof. Background technique [0002] The Beidou satellite navigation system is an independently developed and independently operated global satellite navigation system that China is implementing. The Beidou satellite navigation system consists of three parts: the space segment, the ground segment and the user segment. The space segment includes 5 geostationary orbit satellites and 30 non-geostationary orbit satellites. The ground segment includes several ground stations such as the main control station, the injection station and the monitoring station. , the user segment includes Beidou user terminals and terminals compatible with other satellite navigation systems. Up to now, the Beidou satellite navigation system has launched a total of 16 Beidou navigation satellites and began to p...
