Abstract

The invention provides an assisted positioning device evaluation system, which comprises an assisted positioning data simulation module, a tested assisted positioning device and a comprehensive assisted positioning result evaluation module, and the comprehensive assisted positioning result evaluation module carries out comprehensive evaluation according to a test result of the tested assisted positioning device under the auxiliary signal environment outputted by the assisted positioning data simulation module. After the technical scheme of the invention is adopted, not only can the test cost of development be reduced, but also assisted positioning test results can be comprehensively evaluated and compared, and therefore the quality of products can be more visually evaluated.

Description

technical field [0001] The invention relates to a test and evaluation system of a satellite navigation aided positioning technology, in particular to a test result evaluation system of an A-GNSS aided positioning device. Background technique [0002] GNSS (Global Navigation Satellite System, GNSS) uses navigation satellites for timing, positioning and ranging, and can provide all-weather, all-round and continuous real-time high-precision three-dimensional space for sea, land and air users around the world. , speed and time information. At present, GNSS includes GPS of the United States, GLONASS of Russia, Galileo system of the European Union, and Beidou navigation system of China. Taking the GPS system as an example, the system is mainly composed of three parts, namely the space part, the ground control part and the user device part. The space part is composed of 24 satellites, which are distributed in 6 track planes. The ground control part is composed of the main control...
