Abstract

Up until the end of October 2012, the Chinese BeiDou navigation satellite system (BDS) had launched 16 satellites, and then started providing formal operation services for China and surrounding regions from the beginning of 2013. It is of theoretical and practical significance to do research on Tropospheric wet refractivity tomography based on BeiDou system. The simulation experiment is conducted based on the ephemeris obtained from two line elements (TLE) and SDP4 model, Shenzhen-Hongkong GNSS network and standard atmosphere. The multiplicative algebraic reconstruction techniques (MART) are used to solve tomography equations to obtain tropospheric wet refractivity field. The results show that for the Shenzhen-Hongkong area the tomography precision has not improved obviously by the signals fusion of GPS/GLONASS/BeiDou, and the tropospheric wet refractivity field can be obtained with high precision based purely on the BeiDou system when GPS/GLONASS become unavailable due to certain factors.
