Abstract

The invention belongs to the technical field of satellite positioning, and provides a method and system for GNSS algorithm verification, a positioning terminal and a storage device. The method includes the steps that resolving tasks are obtained from a database; the obtained resolving tasks are distributed to one or more computers in batches; a resolving result, fed back by each computer, of execution of each resolving task is received, wherein each resolving result at least includes one or more of the fixed rate of satellite data and precision of the satellite data; the received resolving results are summarized to obtain a summarizing result. The GNSS resolving tasks are executed in batches, so that the execution efficiency of the resolving tasks is improved.

Description

technical field [0001] The invention belongs to the technical field of satellite positioning, and in particular relates to a method and system for GNSS algorithm verification, a positioning terminal and a memory. Background technique [0002] Global Navigation Satellite System (Global Navigation Satellite System, GNSS) is the full name of all navigation satellite systems, currently mainly including the US Global Positioning System (Global Positioning System, GPS), Russia's Global Navigation Satellite System (Global Navigation Satellite System, GLONASS) , Europe's Galileo system (Galileo), China's Beidou (Compass). The basic working principle of the GNSS receiver is: receive the radio signal sent by the navigation satellite and extract the pseudorange, and calculate its own position in the geographic coordinate system according to more than 4 pseudoranges. The common solution algorithm is the least square method and Kalman filter method. [0003] In the prior art, it is usu...
