| Abstract: | A regional satellite navigation system which is made up of geosynchronous satellites and synchronous satellites with elliptical orbit is proposed. The parameter of the constellation is optimized with the goal that the GDOP should be minimum.The performance of the constellation which is compared with GPS is obtained by simulation.The simulation shows this scheme can meet the requirements in china and its neighboring area. |
