Inertial Microsensor Systems - IMSS

SensorDynamics has achieved a first in combining motion sensors (angular rate and acceleration) with analog-digital electronics (ASIC) in one package to form a large-scale integrated microsensor system that guarantees absolute fail-safe functionality. Applications include electronic stabilization systems, rollover detection and navigation sets for ‘dead reckoning’ without GPS support. IMSS from SensorDynamics are certified to AEC-Q100 or are re-certified after being customized for the application.
