Innovation and Reliability Since 1980

UAV Platforms


The lightweight GEM Hawk (Helicopter) is well suited to
lift the GEM AirBIRD for robust UAV aerial magnetic surveying

The GEM Hawk is a fully functional UAV Helicopter with drone flight control and self-stabilization. GPS guidance, automatic RTL, and even Waypoint capability make this autonomous solution an easy and efficient survey method. Vertical Take Off & Launch (VTOL) makes this platform ideal for taking off in the bush, and flying just over top of trees and topography.

A helicopter UAV is simple compared to a conventional airplane, because the operator does not need to plan for often complicated take-off procedures and landing zones. It also has a minimum of moving parts. Not only does this make it more reliable and easy to maintain, but also more compact and light-weight. One other benefit of the compactness of the power train unit is that it results in very flexible payload and battery areas.

The GEM Hawk is our preferred UAV for the AirBIRD turnkey solution, and ships ready to fly with a rugged flight case.


  • VTOL enables UAV to take off in congested or bushy areas
  • 50 min cruise time at 50 km/hr cruise speed.
  • Autonomous operation
  • Up to 4 kg usable payload
