A New Approach for Regional Ionosphere Recovery Using Carrier Phase Measurements

Xiangqian Liao

Abstract:	A new approach of ionosphere recovery has been developed and described in this paper using a regional area of GPS network. The approach focuses on recovering ionosphere vertical TEC at centimeter accuracy using carrier phase as the principal observable. To eliminate possible satellite and receiver dependent biases, double difference method has been employed. A grid model has been developed along with a streamlined Kalman filter to model and estimate the ionosphere over the network. The performance of the proposed ionosphere recovery method has been tested using data from a regional GPS network currently in operation. The results have indicated that the regional ionosphere estimates were determined at an accuracy of several centimeters.
