基于GP2010的GPS接收机前端模块实现

Implementation of GPS Front-end Circuit Based on GP2010

为了研制自主知识产权的GPS接收机,首先要设计合理的GPS接收机前端模块.结合GPS接收机的工作原理,提出了切实可行GPS接收机的前端电路实现方案,给出了相应的实验数据,并对其中的关键模块及器件选取进行了详细的介绍.结果表明,该前端电路硬件平台是稳定可靠的.

In order to develop a GPS receiver with practical GPS Front-end module, which enables us our own intellectual property, the most important step is to design a to constantly receive GPS signals from the satellites. In this paper, we put forward practicable GPS receiver front-end circuit scheme and give the corresponding experimental data based on the working principle of GPS receiver, and introduce more details about key modules and components selected in the experiment. Ultimately, the result of the experiment shows that the hardware platform of front-end circuit is fairly stable and reliable enough to receive the GPS signals.
