讨论了GPS现代化信号（L2和L5）上民用伪随机码的改进

重点分析了数据通道和无数据通道的优势和区别以及L5上Neumann-Hoffman（NH）码的作用

定性分析了新型的伪随机码的组成和调制方式对GPS信号捕获和抗干扰性能的影响。

Abstract

This paper analyzes the basic characteristics of the civilian Pseudo-Random Sequence（PRS） codes in three bands of the Global Position System（GPS） signals

including generation configuration

modulating mode

message structure and signal energy.In connection with the features of L1 C/A code

it discusses the improvement of the civil PRS codes on GPS L2 and L5 signals

describes the differences and advantages of data and dataless channels and the functions of the Neumann-Hoffman（NH） code at L5 and qualitatively analyzes the effects of the new PRS code structure and modulation mode on the acquisition and anti-interference performances of the GPS signals.
