Abstract
With high-performance ground atomic clock and satellite retransferring feature, CAPS achieved higher positioning and timing precision than traditional GNSS. Positioning and timing high-performance verification test has been conducted by National Time Service Center (NTSC in Xi’an, China) in Xi’an city Shaanxi province. Test results show that (1) the accuracy of the code-phase timing and the carrier-phase timing with single GEO satellite is better than 5 ns and 0.5 ns, respectively, and (2) the accuracy of the code-phase positioning and the carrier-phase positioning with 1 IGSO and 3 GEO satellites is better than 1.5 m and 0.5 m, respectively. The results indicate the ability of high-precision positioning and timing of CAPS.
