GEM’s first airborne project was a vertical helicopter-borne gradiometer created in co-operation with Urtec Instruments and Geotech. It was based on a simple, yet effective self-oscillating Overhauser system. The company also developed the inexpensive GSM-11 airborne magnetometer that contributed to the commercial success of Terraquest Surveys and H. Ferderber Geophysics.

With the development of the Potassium system with its ultra-high sensitivity and fast sampling, GEM advanced even further into the airborne realm. Helicopter-borne magnetometers and gradiometers have been developed including a single-sensor magnetometer (GSMP-35A/25A), vertical gradiometer, and the leading three-sensor gradiometer which has been purchased by various organizations around the world.

GEM continues to make advances in the sky, including the recently upgraded airborne VLF system which uses a new tilt sensor to increase the accuracy and time in which measurements can be made.

We also continue to work on fixed wing installations using the GSMP-35A/25A and have a number of these installations up and running now. Expertise includes consulting on sensors and positioning as well as noise sources that must be addressed in order to make accurate measurements from a moving platform.

GEM UAV Solutions

In our most recent development, we are now building sensors and electronics for Unmanned Airborne Vehicles (UAVs) which are becoming increasingly important in a variety of fields for unmanned airborne surveying.

Core to the UAV business is the new light weight UAV Potassium Magnetometer. GEM has developed several applications which include light weight towed “birds” and fully integrated systems for multi-rotors and mini helicopters.

A Long Term Focus on its Customers
Through its more than four decades of service to the land, airborne and observatory professional community, GEM has continued to seek optimal solutions that will enable its customers to work more cost efficiently and effectively.
