In order to solving the problems,for example: the BeiDou wide area differential system(WADS) now only has one correction which can not adapt differential satellite statues as Normal status,phase adjustment status,orbit maneuver status,Next generation BeiDou WADS is dependent on more systems data,Other WADS algorithms as WAAS are not suitable for BeiDou constellation structure which has GEO and IGSO satellite,so a BeiDou WADS algorithm is proposed to compute 4 dimensional differential correction including satellite clock error and ephemeris RTN errors,only based on monitoring receiver.At last,based on real observations of BeiDou system and the verify results show that the influences of satellite phase adjustment and orbit maneuver are reduced and the positioning un-certainty is remarkable depressed.
