“…The new modernized L2C signal has advantages, such as it is not encrypted, allowing civil receivers to receive the full SNR, the data-less pilot CL code signal has a lower tracking threshold, enhancing signal acquisition and tracking at low SNR [2]. With L2C in addition to the C/A code at L1, dual-frequency receivers can benefit from using the codes at both frequencies, exploit the data-less code channel at L2, and is more prone to eliminate the ionosphere irregularities and resolve phase ambiguity [3,4]. The L2C signal has great superiority for civil applications of GPS, capacitating receivers to measure in highly accurate.…”

The newly broadcast GPS L2C signal will be extensively used due to its superiority. In order to acquire L2C signal fast in a dual-frequency GPS receiver, this paper firstly discusses two traditional acquisition algorithms, then proposes and implements a new algorithm based on the fixed phase relationships among C/A code, CM code and CL code and the fixed relationships of Doppler shift between the L1 channel and L2 channel. The experimental result demonstrates that the new acquisition algorithm can speed up the acquisition process substantially. It also suits other dual-frequency navigation receivers.
