POLAR

The POLAR is a high-end, MEMS-based Attitude and Heading Reference System (AHRS) and Inertial Navigation System (INS). It is perfect for system integration in avionics packages or other attitude sensing applications, and includes:
  • Attitude Heading & Reference System (AHRS)
  • Inertial Measurement Unit (IMU)
  • Inertial Navigation System (INS)
  • Air Data System (ADS)
  • GPS
POLAR has proved itself in a variety of highly dynamic environments, giving outstanding results:
  • Red Bull Air Race
  • MotoGP onboard 'GyroCam'
  • Reno Air Races.
  • Various UAVs as the onboard ADAHRS for the Customer's own flight control computer.

Redundancy built into the POLAR software allows it to survive individual sensor failures while maintaining accurate estimates of attitude and position. Its high-performance MEMS-based IMU is calibrated and compensated over the full industrial temperature range.

Key features:
  • Compact and easy to integrate
  • Combines exceptional navigation and attitude performance device in a wide range of high dynamics conditions and GPS-denied dead-reckoning navigation
  • Supplied as standard in an aircraft-grade anodized aluminium box
  • Optionally it can be supplied as an OEM board for direct integration in the Customer's product
  • It is used as the onboard sensor suite inside UAV Navigation's VECTOR autopilot

POLAR Installation Kit
The optional POLAR Installation Kit (INSKIT) offered by UAV Navigation includes the recommended connector and cable to allow the Customer to integrate the POLAR unit into their system. INSKIT contents:
  • GPS Antenna
  • 15-Pin Micro-D System Connector (fitted with 18" / 45cm cables as shown in the image above).
 

 

 
MG01
Sometimes other onboard systems (e.g. electric motors, cabling etc) can interfere with the readings obtained from the built-in magnetometers in UAV Navigation's Autonomous Flight Control Units (AFCU) and AHRS-INS modules. In these cases, the MG01 provides a remote installation which can be physically located in a safe place far from interference.
