针对B码时统终端的精度、稳定性等问题，结合B码的编解码和北斗/GPS双模授时的原理，从应用角度出发，提出一种利用可编程逻辑器件（FPGA）采集双模授时的时钟和时统终端的设计方法。结果表明：从接收器采集到的秒头和B码的秒头误差控制在纳秒级，从而达到同步授时的效果。

Combining the theories of B code’s encoding and decoding with the bei-dou/GPS dual-mode and the precision, stability and other problems of B code time terminal system, this paper puts forward a kind of designed method using the programmable gate array(FPGA) to get data from mode timing clock and time terminal. The result shows that the second head from receiver and B code can be controlled in the ns level so as to achieve the effect of time synchronization.
