介绍了COMPASS/北斗2号区域导航系统的初步特性和性能评估。2012年3月，通过一个小型区域监测站网络收集了多达三个频率的代码和载波相位测量值。对信号和测量质量进行了分析，并与日本的准天顶卫星系统进行了比较。频率间载波相位偏差具有很高的稳定性，这将有助于三频非差模糊解算技术在未来的精密单点定位应用中的应用。通过与地面氢脉泽进行比较，评估了机载Rb频率标准的性能，并证明其与其他全球导航卫星系统卫星时钟具有很强的竞争力。利用后处理得到的精密轨道和时钟解，研究了目前罗盘/北斗二号导航中可达到的单点定位精度。最后，说明了三频测量和超宽车道模糊解算在短基线相对定位中的优势。
An initial characterization and performance assessment of the COMPASS/BeiDou-2 regional navigation system is presented. Code and carrier phase measurements on up to three frequencies have been collected in March 2012 with a small regional network of monitoring stations. The signal and measurement quality are analyzed and compared with the Japanese Quasi Zenith Satellite System. A high level of stability is demonstrated for the inter-frequency carrier phase biases, which will facilitate the application of triple-frequency undifferenced ambiguity resolution techniques in future precise point positioning applications. The performance of the onboard Rubidium frequency standards is evaluated in comparison to ground-based hydrogen masers and shown to be well competitive with other GNSS satellite clocks. Precise orbit and clock solutions obtained in post-processing are used to study the presently achievable point positioning accuracy in COMPASS/BeiDou-2-only navigation. Finally, the benefit of triple-frequency measurements and extra-wide-lane ambiguity resolution is illustrated for relative positioning on a short baseline.
