摘　　要：分析了BDS/GPS双模松耦合定时模块与紧耦合定时模块之间在成本、功耗、体积方面的差距,以及松耦合定时在完好性监测方面的不足,从而得出紧耦合在定时方面占优势的结论。详细阐述了紧耦合定时模块的硬件设计、定位原理、定时原理及策略,实验结果验证了紧耦合定时在完好性监测等方面的优势。The differences in cost, power consumption and volume between the BDS/GPS dual-mode loose-coupling timing module and the BDS/GPS dual-mode tight-coupling timing module, and the shortcomings of loose-coupling timing in integrity-monitoring are analysed, thereby it is concluded that the tight-coupling has obvious advantage in timing. The hardware design, positioning principle, timing principle and strategy associated with the tight-coupling timing module are demonstrated in detail. The experiments verify the advantage of tight-coupling timing in integrity-monitoring etc.
