Spirent Announces GNSS/MEMS Simulation Software

Spirent Communications has launched of its SimSENSOR MEMS (micro-electro-mechanical system) sensor simulation software.


Spirent Communications has launched of its SimSENSOR MEMS (micro-electro-mechanical system) sensor simulation software.

SimSENSOR is targeted at the R&D environment and enables performance testing of sensor fusion algorithms in navigation systems that include MEMS inertial sensors and one or more GNSS system. The software works in tandem with Spirent’s multi-GNSS constellation simulators by simulating MEMS sensor outputs on a common trajectory with the simulated GNSS signals. Trajectories that include representative human motion gestures, such as arm movements, are included with SimSENSOR.

The software supports the testing of fusion algorithms that take inputs from a wide variety of sensors, including accelerometers, gyroscope, magnetometer, digital compass and barometric height sensors. Representative MEMS noise models and errors such as bias and drift are also included and are available under user control.

“SimSENSOR is designed for customers who want to optimize sensor fusion architectures,” said Rahul Gupta, product manager with Spirent’s Positioning Technology business. “Sensor fusion is increasingly being used to enable a wide range of applications, including indoor positioning.”

Spirent has extensive experience of test systems for blended GPS-inertial technology. In 2007 Spirent launched SimINERTIAL to test inertial navigation systems involving high-grade GPS/inertial units suitable for military applications.

SimSENSOR is now available for order. For more information on the new sensor simulation software, visit the Spirent website.
