Abstract

The invention discloses a satellite navigation system hardware-in-the-loop real-time simulation test platform and a method thereof. The satellite navigation system hardware-in-the-loop real-time simulation test platform comprises a PC-end simulation module, an Ethernet communication module, a satellite signal baseband processing unit and a radio frequency module, wherein the satellite signal baseband processing unit comprises a processor, a bus controller, an internal memory RAM, a satellite signal acquisition module, a satellite signal tracking module, a low-speed bus controller and a data transmission bus. The test platform acquires satellite signals via the radio frequency module, the signals are then processed via the satellite signal baseband processing unit, the signals are then transmitted to the PC-end simulation module in real time for processing via an Ethernet interface, the PC-end simulation module processes the signals and then a processing result is fed back to the satellite signal baseband processing unit, the acquisition and tracking state of the satellite signal baseband processing unit towards the satellite signals are updated, and thus, a hardware closed loop for simulation test is formed.

Description

technical field [0001] The invention belongs to the technical field of satellite navigation and positioning, and more specifically relates to a satellite navigation system hardware-in-the-loop real-time simulation test platform and a method thereof. Background technique [0002] Satellite navigation and positioning technology is of great significance to the development of a country's military and national undertakings. In order to get rid of the dependence on the US GPS positioning system, many countries have carried out research on satellite navigation systems. At present, there are three relatively mature satellite navigation systems, including the GPS positioning system of the United States, the GLONASS positioning system of Russia and the Beidou positioning system of China. According to the principle of GPS positioning, in order to demodulate the complete navigation data, the carrier and code signals that are synchronized with the received signal bits must be reproduced ...
