High-dynamic satellite navigation chip device based on Beidou combined with GPS and GLONASS

Abstract

The invention discloses a high-dynamic satellite navigation chip device based on Beidou combined with GPS and GLONASS. The device comprises an antenna, a low noise amplifier module, a radio frequencychannel module, a comprehensive information processing module, a power supply unit and a complete machine structure, and is characterized in that the antenna is a receiving three-frequency antenna used for GPS, GLONASS and BDS; the low-noise amplifier module is integrated in the antenna, and the low-noise amplifier module comprises a GPS/GLONASS and a BDS low-noise amplifier. The radio frequency channel module comprises a GPS/GLONASS compatible channel and a BDS receiving channel. The comprehensive information processing module comprises a baseband signal processing module, an information processing module and an application processing module; and the baseband signal processing module is used for completing dispreading, demodulation, tracking, bit synchronization, frame synchronization andthe like of GPS, GLONASS and BDS signals. According to the invention, the antenna automatic zero setting technology has an obvious anti-interference advantage; a high-sensitivity receiver technologyhas the advantage of receiving small signals at a low threshold; the low-power-consumption board card design technology has the advantages of low power consumption and long standby time.

Description

technical field [0001] The invention relates to the technical field of satellite navigation chips, in particular to a high dynamic satellite navigation chip device based on Beidou combined with GPS and GLONASS. Background technique [0002] The satellite navigation system is one of the electronic communication systems with the fastest technological innovation and development in the world. The global satellite navigation system currently in operation can provide users with high-precision, all-day and all-weather navigation, positioning, timing and communication services. It is an important part of the information infrastructure of various countries in the world, a major technical support system for national security and national defense, and an important guarantee for national economic security. [0003] With the modernization of GPS, the update and restoration of GLONASS, and the gradual completion of Beidou, multiple sets of navigation satellite systems will coexist in spac...

Problems solved by technology

But generally speaking, the research and development of the core technology of satellite navigation receivers in our country is relatively lagging behind. The development of high-dynamic three-mode satellite navigation is currently only a technical discussion by research institutes and military enterprises in some countries, and has not yet been realized in engineering. Even the report of the test, so our company's breakthrough in this technology and the realization of engineering have filled the gap in the country, with the first-mover market advantage, great market competitive advantage, and huge room for future development
