中文说明：应用背景GPS技术广泛应用在生活、科研、生产领域中，本程序应用于GPS信号的捕获搜星，确定可见的GPS卫星星号、多普勒频偏和码相位的初始相位。得到的结果可以进一步用于跟踪和解算。关键技术 ca_repeat.m用于产生指定ca码的采样序列。CAENCODE.m用于产生CA码。findmax.m用于找到峰值。GPSAcq.m是捕获的主函数。GPS信号的频点、中频频率、采样率在初始化中都可以修改为你需要的参数。 本代码还含有真实的GPS数据。
English Description：
Application backgroundGPS technology is widely used in life, scientific research and production areas and the application in GPS signal capture star search and determine the visible GPS satellites asterisk, Doppler frequency offset and the initial phase of code phase. The results obtained can be further used to track the settlement.Key TechnologyCa_repeat.m is used to generate a sample sequence of a specified CA code. CAENCODE.m used to generate CA code. Findmax.m used to find the peak. GPSAcq.m is the main function of the capture. GPS signal frequency, if frequency, sampling rate in the initialization can be modified for the parameters you need.The code also contains real GPS data.
