Abstract

When the carrier to do a high dynamic motion, it will lead the tracking error to increase, then the degree of nonlinearity of the detector will become large and the equivalent gain response will reduce, so it may lead the satellite signal to loss lock. This paper studies the simulation system of GPS/INS ultra-tight integration under high dynamic environment, it simulates two kinds of dynamic models and the results show the superiority of ultra-tight integration. When the GPS single interrupted, it can continue tracking by INS and it’s able to quickly restore the tracking when signal recovery. Ultra-tight integration also provides a possible for GPS anti-jamming technology.
