摘要

霍尼韦尔组装了一个基于pc的数据采集系统，用于从GPS接收器前端收集数字化射频数据，以及一个测试平台软件集，该软件集使用收集到的射频数据执行频域采集、时域跟踪、伪距计算和GPS位置解的计算。测试平台软件几乎完全用Matlab编写，包括一些c代码文件来构建Matlab可执行(MEX)模块。本文将描述频域处理技术以及执行的其余后处理。

A testbed for frequency domain GPS acquisition and receiver simulation

Honeywell has assembled a PC-based data acquisition system to collect digitized RF data from a GPS receiver front end, along with a test bed software set that uses the collected RF data to execute frequency domain acquisition, time domain tracking, pseudorange computation, and computation of GPS position solution. The test bed software is written almost entirely in Matlab with a few C-code files included to build Matlab executable (MEX) modules. This paper will describe the frequency domain processing techniques and also the rest of the post-processing that is executed.
