The invention provides a real-time testing system of a satellite navigation receiver. With the real-time testing system, requirements that real-time tests are performed on the satellite navigation receiver under different environments can be met. The real-time testing system comprises a base station testing portion and a mobile station testing portion. The base station testing portion comprises a base station receiver, a base station measuring antenna, a control computer and a wireless communication module. The base station measuring antenna is disposed at a fixed coordinate point with known position coordinates, and the base station receiver is connected with the base station measuring antenna, the control computer and the wireless communication module respectively. The mobile station comprises a mobile station receiver, a mobile station measuring antenna, an inertial navigation device, a wireless communication module and a monitoring computer. The to-be-tested satellite navigation receiver is mounted on the same carrier in motion with the mobile station testing portion, and the monitoring computer is connected with the mobile station receiver and the to-be-tested satellite navigation receiver respectively. The mobile station receiver is connected with the mobile station measuring antenna, the inertial navigation device and the wireless communication module respectively.
Description
technical field [0001] The invention relates to the field of satellite navigation product testing, in particular to a real-time testing system for satellite navigation receivers. Background technique [0002] The satellite navigation and positioning system uses satellites to transmit radio signals for positioning and navigation, and has all-weather, high-precision, fast and real-time three-dimensional navigation, positioning, speed measurement and timing functions. The satellite navigation and positioning system consists of three parts, namely the space satellite constellation part, the ground monitoring part, and the user equipment part (satellite navigation receiver or module). The current Global Navigation Satellite System (GNSS, Global Navigation Satellite System) includes GPS in the United States, GLONASS in Russia, Beidou satellite navigation system in China, and GALILEO system in the European Union. The satellite network of China's Beidou satellite navigation system ...
