Abstract The design principle of monitoring system of widearea realtime precision positioning system is described and a new integrity monitoring scheme is design by using twoway date. The new scheme has sufficient integrity monitoring stations while the data source reference station can not be reduced, so that the system can have bigger integrity monitoring area and in the same time,guarante the accuracy of differential product.In addition the key technique of integrity monitoring is expounded, including the differential product monitoring,external position coincidence monitoring,estinate of internal coincidence,state of satellite clock,etc.
