　　Integrity monitoring is an important means to guarantee the integrity of satellite navigation system.Receiver autonomous integrity monitoring(RAIM),as a client integrity monitoring method,has a lot of advantages such as not dependent on external equipment,low cost and easy to implement.Therefore,it is widely used in integrity monitoring.Traditional RAIM methods comprise RAIM algorithm based on Kalman filter and snapshot algorithm based on pseudorange observation.
