GPS + Sensor Simulation

Modern navigation systems integrate multiple location-aware sensors to improve performance and reliability.

GPS RF simulators, like Spectracom’s GSG series, are able to test the integration of a GPS/GNSS receiver into the nav system by generating signals corresponding to virtually any condition including vehicle dynamics. Simultaneously, they can also generate signals for other types of sensors for a comprehensive system test of the navigation system.

Sensor Simulation Option

As the simulator generates navigation satellite data for a given trajectory, it simultaneously calculates position and attitude data in six degrees of freedom in real-time; forward/backward, left/right and up/down as well as the rotations about three perpendicular axes, pitch, yaw, and roll. Th data corresponding to different types of sensors can be queried up to 10 Hz.

Sensors Simulated

Type Description Units
Accelerometer Acceleration along the XYZ axes g
Linear Accelerometer Acceleration along the XYZ axes excluding the force of gravity g
Gravimeter Gravitational force to XYZ axis g
Gyroscope Angular speed around the X,Y, and Z axes radians/sec
Odometer Total distance traveled meters
3D Odometer Total distance traveled in the X,Y, and Z axes meters

GPS Simulator Model Compatibility

The Sensor Simulation Option works with any 16-channel or higher Spectracom GSG-5 or -6 series simulator.

Note: the sensor simulation option is included when purchasing the real-time scenario generator option (OPT-RSG).
