A solution to time synchronization and time jitter detection

In the passive TDOA system,positioning accuracy and stability of the system are two important standards for evaluating merits of the system.A method of using auxiliary stations to transmit time synchronization detection signal to ensure time synchronization between stations and to improve positioning accuracy is proposed based on analyzing the two key affecting factors.At the same time,detecting the time jitter of the receiving station by using the signal is reached.Theoretical analysis and preliminary simulation experiment verifies that the method is effective to improve the accuracy of measuring the time difference and enhance the stability of TDOA system.At last,principle of the whole system and main data processing of the main station are given.
