摘要

为检测高动态GPS(Global Positioning System)信号

需要设计码环及载波环的捕获与跟踪数字系统.在高动态下

在GPS信号的码跟踪和载波捕获与跟踪问题中最关键的是要解决在高加速度下的载波跟踪问题.主要讨论了在高动态下

结合GEC公司的十二通道相关器GP2021

载波跟踪环路的特性并在此基础上提出了一个新的方法来改善载波跟踪环路的性能.

Abstract

To examine the GPS signal in high dynamic situation

it is necessary to design code circus and carrier circus.To acquire and track the digital system

in the high dynamic situation

the most important aspect in the problems of code tracking as well as carrier acquisition and tracking is to solve carrier tracking problem.In the high dynamic situation

using the twelve channels correlator -GP2021 of GEC corporation

this paper analyses the peculiarity of carrier tracking circuit.On the ground of it

it also presents an novel method to improve the performance of the carrier tracking circus.
