Abstract
Time interval measurement plays an important role in time synchronization system. Precise time
interval measurement can improve the accuracy of positioning system. The delay line interpola-
tion method with electron counter is widely used in recent years, which can meet the need of high
accuracy as well as large ranging scale.
