中文摘要:

作为四个全球卫星航行系统之一,指南针不仅为放提高卫星可见性和可获得性,航行并且预定(PNT ) 为在中国和包围区域的用户,而且为全球用户改进 PNT 精确。在卫星可见性和精确的冲淡的改进在 GNSS 相容性和互操作条件下面被分析。到全球用户,特别用户们能从指南针的联合获得的好处, GPS, GLONASS,和伽利略航行系统的指南针卫星航行系统的贡献,用模拟数据被分析。

英文摘要:

As one of the four global satellite navigation systems, Compass not only enhances satellite visibility and availability for positioning, navigation and timing (PNT) for users in China and the surrounding areas, but also improves PNT precision for global users. The improvements in satellite visibility and the dilution of precision are analyzed under GNSS compatibility and interoperation conditions. The contribution of the Compass satellite navigation system to global users, especially the benefits that users can acquire from the combination of Compass, GPS, GLONASS, and Galileo navigation systems, is analyzed using simulation data.
