基于GPSD的高精度校时系统
The high-precision time synchronous system based on GPSD
摘要
Abstract
In order to correct the time of astronomical facilities precisely, a method of building high-precision NTP server is introduced, which can collect valid timestamp from the NMEA data, and keep high accuracy using PPS signal. The hardware circuit was constructed using G591 GPS module and the steps of building the high-precision NTP server are proposed. Three experiments show that the NTP server based on GPSD is precise, stable and reliable.关键词
