Problems solved by technology

[0003] Satellite-based high-precision positioning uses relative positioning. By setting up an RTK base station, its target positioning terminal must receive information from the RTK base station through the operator's mobile network (such as 4G / 5G) in addition to receiving the navigation message sent by the satellite. Differential data, and then complete the differential calculation to obtain accurate location information, and then send the location information through the operator network. The positioning terminal not only needs to receive a large amount of differential data, but also needs to complete the calculation, which will lead to a significant increase in power consumption of the terminal.

Abstract

The invention discloses a method for realizing low-power-consumption work of terminal equipment based on satellite positioning. The method comprises the following steps: receiving a satellite navigation message by using an RTK base station, sending positioning difference correction data obtained by calculation to a background system server, and meanwhile, receiving the corresponding satellite navigation message by using a positioning terminal and sending the navigation message to the background system server through the NB-IoT or the 5G-mMTC; the background system server carries out differential calculation according to the received data, outputs the position data of the positioning terminal, transfers the calculation load of the positioning terminal equipment to the background system server, and only needs to receive and forward the satellite navigation message, thereby reducing the power consumption of the positioning terminal.

Description

technical field [0001] The invention relates to the technical field of satellite positioning, in particular to a method for realizing low-power operation of terminal equipment based on satellite positioning. Background technique [0002] Satellite positioning is currently available in China's Beidou, American GPS, European Galileo, and Russian GLONASS, which have been widely used. According to the positioning method, satellite positioning is divided into single point positioning and relative positioning (differential positioning). Single-point positioning is a way to determine the position of a receiver based on the observation data of a receiver. It can only use pseudo-range observations and can be used for rough navigation and positioning of vehicles and ships. Relative positioning (differential positioning) is a method of determining the relative position between observation points based on the observation data of two or more receivers. It can use both pseudo-range obser...
