     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.
