ADMA-Slim mini GNSS/inertial system: If size and weight matters
The new full-fledged ADMA-Slim GNSS/inertial system 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. 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.
ADMA-Slim is based on the proven ADMA technology for centimeter accuracy in positional data acquisition. It delivers precise, smooth and consistent signals even when GNSS reception is poor.
Technical data for ADMA-Slim can be found in the tables below or in the data sheet.

Properties
- Fullfledged GNSS/inertial system with proven ADMA technology

- Robust MEMS inertial sensors in strapdown technology with 5, 10 or 15 g
- Improved satellite reception via Multi-GNSS (GPS, GLONASS, GALILEO, BEIDOU)
- Also as Dual Antenna version available
- Mounting with high power magnets possible
- Direct attachment of the GPS antenna to the inertial sensor technology possible
- Available in a waterproof housing or as unhoused version for OEMs
