ADMA-Micro: Our smallest GNSS/Inertial Navigation Unit
The ADMA-Micro GNSS/inertial navigation unit achieves highly accurate measurements of position, velocity, angles, rotation rates or accelerations of a moving object. This GNSS/inertial navigation unit is small, rugged and low powered, making it ideal for a range of applications including:
Different designs make it possible to select the right design for a variety of applications:
-
Autonomous vehicle (AV) operation
-
ADAS Evaluation e.g. ACC, FCW, AEB (VRU, Car2Car), LSS (LDW, LKA)
-
Simultaneous localization and mapping (SLAM)
-
Validation of predictive vehicle safety functions with e.g. Camera, Radar, Lidar sensors
-
Vulnerable Road Users (VRU) Tracking
-
Comprehensive vehicle safety functions with connected sensor systems and V2X

The performance figures given are based on measurements taken using the latest firmware version 35.3. Performance figures for
comparable systems were obtained at different times and using different firmware versions and are therefore only comparable to a
limited extent.
