The research background and the workflow of gravity matching navigation are introduced.Simulation model,which employes the true gravity anomalies data on the Chinese coastal waters,is designed by two different algorithms,multiple model adaptive Kalman filter and the method of the absolutely difference's square.Simulation testing is implemented in two routes that have different changing magnitude in the gravity anomalies.And satisfying results are obtained.It is testified the technological feasibility of gravity matching.
