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.


  • Fullfledged GNSS/inertial system with proven ADMA technology
  • Extremly small, lightweight and convenient size
  • Measuring of vehicle movements in all three measuring axes, even with GPS outage
  • 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
  • Compatible with all common overrunnable platforms
  • Optional extendable, e.g. with RTK or DELTA option

ADMA-Slim is available in three different versions

  • Standard version with 7 LEMO connectors in a waterproof housing
  • Single connector version with MIL connector in a waterproof housing
  • Unhoused OEM version

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.
