Single Navigation Satellite Orbit Determination and Evaluation by SLR

  • Abstract: Based on carrier phase observation,a single navigation satellite orbit determination strategy is present for local region observation station net. Moreover a new carrier phase cycle-slip detection and correction arithmetic,called the O-C,is designed to pre-process static carriers phase data,which is different from others by adopting prior orbits and clock information. To confirm the validities of the strategy and the O-C arithmetic,the orbit determination is performed for a experimental satellite of the second generation satellite navigation system. The 3-days-arc POD results processed by the SHORD software show that the general RMS are about 18 cm,and the differences of 1-day-arc overlap orbit are 0.61 m and 8.09m in radial and three-dimensional,respectively. Consideration of the time system bias between the orbits and the SLR,the average differences of the 24 hour prediction orbits are 0.50 m compared with the SLR observation. The average differences of determinate orbits and the 24 hours prediction orbits are 0.28 m and 1.34 m,respectively.
