摘要 GPS L2C信号是GPS系统在L2频段上的新型民用信号,其主要由时分复用的CM码与CL码组成。CL码上没有导航电文的调制,所以可以进行更长时间的相干积分,适合于捕获微弱信号。但CL码码长较长,运用传统的捕获方法,难以直接捕获。提出一种基于分块折叠的捕获方法,利用折叠码与分块捕获技术,快速直接捕获CL码。与传统捕获算法相比,新算法能够实现捕获速度上的提高,且可根据需要优先考虑捕获速度或灵敏度。 The GPS L2C signal is a new civilian signal transfered on L2. It is a Time Division Multiplexed （TDM） signal formed by CM code and CL code. The dataless property of the CL code is potentially valuable for situations where receiver sensitivity is critical. However, the CL code is very long, making direct acquisition of the code phase challenging. This paper presents a new direct acquisition means based on block acquisition and folding code technology. Compared with the traditional acquisition algorithm, the new algorithm can improved acquisition speed, and can give priority to the speed or sensitivity with need.
