Galileo系统的频率和信号结构

Introduction to Galileo's tentative plan for its frequency and signal structure

根据近期公布的由Galileo信号任务组制订的Galileo频率和信号结构计划,列出了Galileo选用的频率和信号结构,包括数据调制、伪随机噪声码扩频的实施等,它考虑了和GPS系统的全兼容和相互共用问题,但对码序列选择、导航电文格式内容等方面尚未确定,有待今后进一步研究确定后公布。

As recently the Galileo signals in space have been presented to the world by European Commission Signal Task Force,hereby, the Galileo's tentative plan for its frequency and signal structure are quoted for information purpose only. It includes the date message modulation scheme,PRN Code frequency spread implementation's well as the full compatibility and interoperability with GPS consideration, but the type of direct-sequence code and navigation data message formate are not defined yet.
