Patent ID: 8359182

Claim:
A method for evaluating performance of MEMS inertial sensors comprising: field-testing a reference inertial sensor to generate reference field-test data including a real kinematic inertial signal from the field-testing, operating conditions experienced by the reference inertial sensor during the field-testing, and GPS signal conditions experienced by the reference inertial sensor during the field-testing; lab-testing a plurality of MEMS inertial sensors to generate static error data for each tested MEMS inertial sensor; calculating a sum of the reference field-test data and the static error data for each MEMS inertial sensor to generate an emulated field data for each MEMS inertial sensor, and calculating an average position drift during a GPS signal outage; and processing, with a processor, the emulated field data for each MEMS inertial sensor with a GPS field data to evaluate performance of the plurality of MEMS inertial sensors for characterizing how the MEMS inertial sensor will operate during varied GPS signal conditions.
