- W4387191967 abstract "This paper designs an early warning system of Bidou high precision positioning and laser radar measurement technology. The purpose is to improve the accuracy of Bidou satellite navigation positioning and laser radar measurement, and reduce the bit error rate of the output signal. The system consists of 5G positioning network, time synchronization device and receiving terminal. In terms of algorithm, this paper uses the positioning equation of Bidou and 5G to establish the mathematical model of joint positioning. The Gaussian - Newton method in the least square method is used to transform the nonlinear equation into a linear equation. Its hardware equipment mainly includes STM32 chip, BD-ATGM332D-5N-3X module and LCD12864 module, which jointly build a simple satellite receiving, positioning and display system scheme. Software design mainly includes navigation module and SCM circuit connection principle, system workflow, LCD12864 display module program, correction algorithm, etc. Experiments show that compared with the traditional Bidou navigation tool, the longitude error of the system is reduced from 0.43% to 0.30%, and the latitude error is reduced from 0.14% to 0.08%. This method has better stability and can reduce the error caused by geographical location." @default.
