  • Methods and systems for evaluating the performance of MEMS-based inertial navigation systems
    Patent number: 8359182
    Abstract: Disclosed are systems and methods for evaluating the navigation performance of MEMS inertial sensors. The method uses MEMS inertial sensors static data signals to estimate the static sensor errors and combines them with a reference kinematic signal obtained through field testing of a high-grade inertial sensor. Such emulated field data may then be processed with the corresponding GPS data collected in the same or different field test to evaluate the navigation performance of the MEMS inertial sensors.
    Type: Grant
