A wide variety of devices, on land, sea and air, require stabilization in order to carry out their intended function. Examples include:
- Stabilization and pointing for a ship-mounted satellite antenna.
- Gimbal stabilization for a camera array on a ground-based vehicle.
- Antenna stabilization and pointing for a UAV satcom installation, SATCOM On The Move (SOTM).
Since 2004 UAV Navigation has accumulated extensive experience in the professional UAV sector, providing flight control solutions for manufacturers of Fixed Wing Platforms, Rotary Wing Platforms and Target Drones. In addition to this, the Company has also provided attitude sensing and telemetry solutions for manned aviation.
UAV Navigation is now leveraging this experience to provide an outstanding platform stabilization and antenna pointing solution.
At the heart of this solution is UAV Navigation's POLAR family, a high-end, MEMS-based, Air Data Attitude and Heading Reference System (ADAHRS) and Inertial Navigation System (INS). It has been designed for system integration in avionics and other attitude sensing applications. Its reduced size, weight and ample interface options make it an ideal choice for system integrators seeking a unit to embed into their system.
The POLAR family is also used as the ADAHRS unit within UAV Navigation's range of autopilots, providing precise attitude estimation, dead reckoning navigation and exceptional performance in highly dynamic conditions.
Whatever the application, UAV Navigation's POLAR ADAHRS provides a reliable stream of information about its dynamic state in order to provide a pointing or stabilization solution. All the necessary sensors (gyros, accelerometers, magnetometers, GNSS, Air Data System etc.) are contained within the compact unit; just connect to power and GNSS antenna (plus pitot/static tube where appropriate) and the unit is ready to go. The POLAR also includes a control unit, enabling it directly to control the servos in a gimbal; it also communicates via all the standard protocols.
POLAR family has proven itself in a wide variety of dynamic environments giving outstanding results - particularly in terms of inertial navigation where it has held its own against Fibre-Optic Gyroscope Systems (FOGS) units - an impressive achievement considering it is based on MEMS technology.
