SimSENSOR extends the capabilities of Spirent’s multi-GNSS simulators by simulating MEMS sensor outputs on a common trajectory with the simulated GNSS RF signals. The simulated MEMSs sensor outputs include user control of representative noise and errors (bias/drift).
With MEMS sensor modeling, simulate up to 4 streams of data from sensors such as accelerometers, gyroscopes, magnetometers, compasses, and barometers. To obtain more accurate positioning for location-based services and navigation, designers and integrators combine GNSS navigation with these sensors.
The combination of these sensors is known as “sensor fusion” or “signals of opportunity.” SimSENSOR enables sensor fusion algorithm testing in the lab, allowing fine-tuning and debugging of the navigation algorithms across a range of operational test scenarios.
Transportation Requires a Fusion; Now to Test It
Inertial navigation systems (INS), like most navigation systems, have evolved through countless iterations and improvements over many years. An INS, unlike other navigation technologies, does not rely on any external signals or inputs to aid navigation. It is, therefore, extremely difficult to spoof, jam or disrupt the system, and solar flares, ground/sky visibility and climate […]
