摘要
介绍了Galileo系统开放服务接口控制文件中导航信号及电文的概况,并在如何满足导航电文中各种不同参数数据的时效性、如何缩短用户接收机导航数据接收时间、如何支持多系统互操作等方面对其特点进行了分析介绍。
After brief introduction of the new issued Galileo Open Service Signal In Space Interface Control Document （ OS ICD）, some new features of the ICD was analyzed and discussed, including how to satisfy the requirements of the varies parameters in navigation message on time, how to shorten the data receiving time of the user receiver and how to support the multiple system interoperability.
