Abstract

The interacting multiple model algorithms were introduced into GPS positioning. The constant velocity model and current statistics model were selected. A method using the relation of location estimation and acceleration was presented to adjust the acceleration variance adaptively. The strong tracking filter was utilized to improve the adaptive tracking performance when there was a sudden maneuver. Simulation and run in test were carried out employing GPS simulator and NovAtel differential position system as well as NovAtel receiver, respectively. The results indicate that this adaptive algorithm has higher accuracy than normal current statistical model as well as NovAtel receiver.

Key words： GPS; positioning accuracy; interaction multiple models; current statistical model
