A Primary Assessment of Zone-Divided Corrections of BDS Decimeter Level SBAS
The main task of Decimeter Level SBAS (Satellite Basic Augmentation system) is obtaining the BDS observation of the reference station,preprocessing,time synchronization,precise orbit determination,computing real-time precise orbit and clock error correction,real-time integrity analysis,zone-divided integrated correction processing and sending the precise differential and integrated information to user.User can use this information to survey and positioning.This paper shows the way to obtain the differential and integrity information by using the reference station original observations,and broadcast the information by GEO satellite.The user put the information into use of real-time dynamic PPP (precise point positioning).The result shows that the user”s coordinates will converge to 1 meter quickly,and 1 hour result will reach 0.3-0.4 meter on three components of NEU.The result primarily assesses the feasibility and stability of the system.
