Inertial Measurement Unit ADMA-Slim: If size and weight matters

The new full-fledged Inertial Measurement Unit has been specially developed for applications with space or weight restrictions. It is smaller, lighter and more compact, without limitations in functionality or quality of measurement data. The ADMA-Slim is the perfect choice for applications in motorcycles, overrunnable platforms for GSTs (Guided Soft Targets) or VRUs (Vulnerable Road Users such as pedestrians or cyclists), for example.

Applications

One of the key advantages of the ADMA is its excellent suitability for installation on overrunable platforms. Unlike many other inertial devices, the ADMA does not require a lengthy initialization process. The stability of the Kalman filter guarantees reliable results without the need for reinitialization even after an overrun of the platform.

Additionally, the ADMA Inertial Measurement Unit is also suitable for all other testing applications, such as VD (vehicle dynamics) or ADAS (Advanced Driver Assistance Systems) testing. Its robust design and stable performance make it a versatile tool for various testing scenarios.

ADMA-Slim Inertial Measurement Unit is available in three different versions

The Inertial Measurement Unit ADMA-Slim is available either with an L1 GNSS receiver with SBAS and DGNSS correction data reception capability or with an L1/L2 GNSS receiver with RTK2 correction data reception capability, allowing for position accuracy down to the centimetre.
