We introduced a design method of DSP-based System of time uniform  which combine the GPS and the Compass to calibrate the time. The system can use UTC (Coordinated Universal Time) of the GPS or the Compass for time base  to generate absolute time and different frequency of synchronous signals. We used DSP (Digital Signal Processor) to calculate the satellite information which includes the UTC time. After getting the UCT time information  put it into the CPLD (Complex Programmable Logic Device) for correction of time delay and serialization to output. Meanwhile  we divided 1PPS (one-pulse-per-second) signal of the GPS and the Compass into 20Hz  50Hz  and 800Hz synchronous signal. And we analyzed the precision of time and frequency. To conclude  the uncertainty of system absolute time is less than 100ns  the uncertainty of system synchronous signals is less than 20ns. This system is easy and flexible for use  stable and reliable in performance. 2010 IEEE.
