我目前正试图以RAWX格式处理来自uBlox接收器的一些数据，以仅使用GLONASS数据计算精确位置。使用最新版本的RTKLib，我已成功为流动站数据创建了一个.obs文件，该文件仅包含来自GLONASS卫星的原始定时数据。
我正在使用包含GLONASS观测的军械测量的基站观测数据。但是，我似乎无法在RINEX .n文件中找到GLONASS卫星的星历数据。
我从http://cddis.gsfc.nasa.gov/Data_and_Derived_Products/GNSS/broadcast_ephemeris_data.html下载了星历数据，但这似乎不起作用，当我使用星历数据运行rnx2rtkp并结合我的流动站和基站数据时，结果是带有标题的文件但没有计算的位置。
GLONASS星历数据是否有可靠的来源？或者你认为运行rnx2rtkp后空文件的问题出在其他地方吗？

答案 0 :(得分：2)
所以事实证明我误解了我正在使用的星历文件。根据{{3}}，GLONASS星历表文件被表示为[yy] g，因此，当我使用。[yy] n时，这包含GPS星历数据而不是GLONASS。
我的错误在于思考.n是任何GNSS的星历数据的标准扩展，而不仅仅是GPS。
GLONASS星历数据可以在任何特定日期从/ [yy] g子目录中的NASA轻松获取，例如RINEX standard
