Abstract.
This paper demonstrates the performance of a deeply integrated GPS/inertial architecture under extreme canopy coverage, where traditional receiver technology fails to acquire and track GPS signals. GPS and inertial experimental data collected in various canopy coverage areas are applied to evaluate the system performance. Test results demonstrate that the deeply integrated approach enables reliable trajectory reconstruction capabilities and maintains sub-meter level of differential positioning precision for cases where the GPS signal is severely attenuated by the canopy.
