Acquisition for GPS C/A code and P(Y) code

Abstract:

An improved global positioning system satellite signal acquisition method. The method of the invention reduces the number of operations in the block correlation used in determining Doppler frequency and time of the received GPS C/A or P(Y) codes. Reducing the number of operations in block correlation increases acquisition speed making it conducive to commercial and military GPS receivers

Abstract(Chinese):

改进的全球定位系统卫星信号采集方法。本发明的方法减少了用于确定接收的GPS C / A或P（Y）码的多普勒频率和时间的块相关中的操作次数。降低块相关操作次数提高了采集速度，有利于商用和军用GPS接收机
