SimINERTIAL

Inertial and Integrated GPS/Inertial (IGI) Sensor Testing

Overcoming PNT/GNSS positioning challenges with precision inertial sensor emulation, for powerful IGI testing

Integrating inertial sensors is an effective way to overcome the weaknesses of GNSS positioning systems. However, it also adds a set of challenges to the development process. Once inertial sensors have been verified, it is necessary to test the complementary positioning systems alongside each other.

SimINERTIAL enables the controllable generation of inertial sensor outputs needed to test the IGI repeatably in the lab. Supporting the leading embedded GPS/inertial systems (EGIs) and inertial measurement units (IMUs), SimINERTIAL utilizes the GSS9000’s RS422 interface to bypass the physical sensors, inputting emulated inertial outputs synchronous with simulated GNSS.
