弱信号GNSS接收机技术研究

Research on Technologies of GNSS Software Receiver for Weak Signal

本文围绕如何实现GNSS接收机在弱信号条件下定位的问题,从弱信号的捕获、跟踪和定位解算三个方面展开研究,在软件接收机平台上开展了GNSS民用频点的弱信号接收技术实验验证,为弱信号GNSS接收机的研发及设计提供了依据。

This paper focuses on how to implement the positioning of GNSS receivers under weak signal conditions and studies the acquisition,tracking and positioning of weak signals, and carries out the weak signal reception of GNSS civilian frequencies on a software receiver platform. The verification of experiments provides a basis for the development and design of weak signal GNSS receivers.
