High precision navigation for vehicles

Differential satellite navigation (DSNS) has the potential for precise navigation of air and surface vehicles if the severe integrity problems can be solved. A complementary combination of DSNS and inertial sensors will improve the dynamic response significantly as well as the integrity. Simulations and flight tests have demonstrated that position accuracies in the decimeter range can be reliably realized for horizontal and vertical position components. Some applications, e.g. laserprofiling, flight inspection and automatic landings, demonstrate the high potential of DSNS
