A Simple and Fast Method for GPS Signal Acquisition
摘要
Abstract
Based on popular GPS signal acquisition methods,a simple and fast method is proposed. In about 1 ms,the method can complete a whole-code detection and acquisition of one satellite in a Doppler frequency shift. FPGA simulation shows in comparison with the traditional acquisition methods this method not only reduces the consumption of resources and time,but also ensures that a Doppler frequency shift of the C/A code phase is obtained in a C/A code period. The acquisition is more simple and fast.关键词
