摘　　要：本文设计了基于MAX2769射频前端,可采集L1波段的民用GPS软件接收机。将采集到的GPS信号,转换为数字中频信号,然后通过对信号的捕获、跟踪,获得卫星与接收机之间的相对伪距,并最终用于定位解算。This paper introduces the design of a software receiver for L1 - band civilian GPS applica- tions. An RF front end is designed with MAX2769. Using the RF front end, the real GPS satellite da- ta are collected and converted to IF signal. Then through acquisition and tracking for the signal, we can get the relative pseudorange between the satellite and receiver, which is used to calculate the position of the receiver.

关 键 词：GPS软件接收机 射频前端 捕获 跟踪 伪距
