Geophysical Surveys

Helicopter Logistics have contributed to the development and growth of the airborne geophysical survey industry for over 25 years. Helicopter Logistics specializes in low level mapping (< 30m) using under-slung (towed) systems. Typically these are Airborne Electromagnetic (AEM) and Magnetometer (Helimag) systems on a 100 to 150 ft line beneath the helicopter. Stinger systems are also operated by the company.

Helicopter Logistics provides airborne geophysical survey services throughout all states and territories of Australia, as well as internationally into countries. Depending upon the project, we utilize a range of helicopters from the Robinson R22 to the Eurocopter AS350B3.


Helicopter Logistics provides specialised services to most of the leading airborne geophysics companies in Australia. We provide services to many of the major exploration companies including BHP, Rio Tinto, Newcrest, and IGO.


Airborne’s XTEM XTEM is an Electromagnetic (EM) system with a 25 metre diameter transmit loop and is towed on a 120ft line with a Squirrel helicopter. Helicopter Logistics is proud to have been associated with GPX for over 10 years and during that time a variety of EM and Magnetometer systems have been operated throughout Australia.


During a HeliSAM survey a 70kW HPTX70 transmitter is positioned on the survey site and produces a high amplitude, high quality, precisely timed signal whilst the helicopter flies a survey pattern across the survey area whilst towing a Magnetometer.


Helicopter Logistics has gained an enviable reputation for safety and professionalism and is a member of the International Airborne Geophysics Safety Association BARS (Basic Aviation Risk Standard) approved for geophysical operations.
