| Abstract: | The middle precision constant temperature crystal clock may realize the function of the high precise crystal clock when it was controlled and adjusted by Microcomputer and GPS PPS signal.The GPS Synchronization clock can solve the problems of the GPS short-term invalidation and low precision of the constant temperature crystal,which is characterized by low price and high precision.The results of field tests show that the accuracy of the GPS synchronization clock is enough to the Transient Electromagnetic me... |
