由于当前的卫星导航系统正在从单一的GPS向多GNSS星座转变，多星座接收机将变得流行。传统的特种卫星系统信号时域和频域快速捕获算法都有其自身的不足。因此它不能处理调制和码长不同的多星座信号。将介绍一种在多星座接收机中实现的通用快速捕获算法。实践证明，该算法具有实用价值，并且能够兼容GPS、GLONASS、Galileo、COMPASS等不同类型卫星信号的采集。
Multi-constellation receivers will become popularity since the current satellite navigation systems are transforming from the solo GPS to multi GNSS constellations. The traditional fast acquisition algorithms in time domain and frequency domain for signal of special satellite system have their own shortages. So it cannot process multi-constella-tion signals which modulation and code length are different. A universal fast acquisition algorithm implemented in multi-constellation receiver will be introduced. It has been proved that the algorithm has practical value, and is compatible on acquiring different types of satellite signals, such as GPS, GLONASS, Galileo, and COMPASS, etc.
