导航卫星自主导航，是实现导航电文在轨自主更新的有效途径。它是在轨卫星完全利用安设在它上面的测量设备和计算装置，通过卫星自行导航信息采集，进而实施在轨导航数据处理，生成导航电文，发送给用户，而不依赖于地面设备支持的导航。本文论述了导航卫星自主导航对导航电文的更新方法及其相关问题。
導航衛星自主導航，是實現導航電文在軌自主更新的有效途徑。它是在軌衛星完全利用安設在它上麵的測量設備和計算裝置，通過衛星自行導航信息採集，進而實施在軌導航數據處理，生成導航電文，髮送給用戶，而不依賴于地麵設備支持的導航。本文論述瞭導航衛星自主導航對導航電文的更新方法及其相關問題。

The satellite autonomous navigation is an effective way to realize an autonomous update to the navigation message on the orbits; it is that the on-orbit satellites fully rely on the measuring device and calculating device installed on them through satellite navigation information collection on their own, then carry out in-orbit navigation data processing, generate the navigation message, send it to the user, and it is the navigation that does not depend on ground equipment support. This paper discusses the updating method and related problems using the satellite autonomous navigation for the navigation message.
