Abstract
Synchronous jitter is one of the factors that influence GPS receiving precision a lot. Jitter is the effective data offset off the ideal position in a data stream, which is divided into deterministic jitter and random jitter. A theoretical analysis was done to the influence of jitter. It can be seen that bit error rate gets larger due to the jitter of synchronous clock. By means of a simulation platform, a simulation was done to the synchronous jitter influence on bit error rate in the circumstance of white noise and single frequency interference. The result shows that as the synchronous jitter gets larger, the system bit error rate gets larger and the system function gets worse.
