摘要
Abstract
Equipment delay error is an important factor to implement two-way time synchronization in pseudo-noise code ranging system. And the accurate calibration is the key technology to reach a good time synchronization. Regarding to the equipment time delay, a new definition of equipment time delay with clear physical meaning was proposed. A scheme implementing delay calibration in two-way time synchronization was designed. The delay calibration technique was validated on the hardware platform of time synchronization station. And the experiment results show that the precision and accuracy of delay calibration reaches sub-nanosecond level.关键词
