Pegasus Airborne Systems is a spin off and sister company to the long running and very successful Atlas Geophysics. Pegasus Airborne’s focus is the acquisition of ultra-high resolution airborne geophysical data, primarily magnetics and photogrammetry but also incorporating other geophysical methods, using autonomous unmanned survey aircraft, as well as the ongoing development of UAV survey aircraft and geophysical survey systems. Over the last five years Pegasus’ team of UAV, electronic, and software engineers, along with our geophysicists, have developed a range of fully autonomous unmanned geophysical survey aircraft and specialised UAV mounted airborne geophysical survey systems.


The company has developed a range of autonomous aircraft including fixed wing, rotary wing and multi-rotor configurations ensuring that the right aircraft is tailored to the right payload to make every project a success. Along with airborne magnetics and photogrammetry, the company can also acquire other data types such as LIDAR, multispectral and hyperspectral.

Paired up with Atlas Geophysics, the team can offer total airborne and ground geophysical solutions second to none, with all projects professionally executed to a high and more importantly, safe standard. As a team, Pegasus and Atlas have the expertise and the tools to deliver every time, anywhere in Australia or internationally, for more information on our UAV services please view our UAV services page.


Reasons to use a Pegasus UAV survey over a conventional manned survey are:

  • Safest magnetic survey option available, practically zero human risk. There have been numerous serious incidents in the low-level geophysical airborne survey sector, some resulting in unfortunate fatalities.
  • Fast production, 20x quicker than ground surveys.
  • Fast data turnaround, preliminary data can be available to the client within hours of a survey flight, final data and grids delivered within a few days post survey completion (dependent on survey size).
  • Minimal environmental impact, very quiet aircraft means minimal disturbance to farm or wild animals.
  • Minimum survey height only constrained by tree height.
  • Accurate terrain following and draping unachievable by a conventional manned aircraft.
  • Bird and sensor altitude measured using GPS and laser, highly accurate data point 3D positioning and generated digital terrain.
  • Data GPS located relative to bird (and sensor) rather than the aircraft results in accurate data positioning. Unlike our competitors who just sling a free swinging magnetometer under their GPS positioned drone.
  • Pinpoint line navigation, deviation typically < 2m off line.
  • 10hz sampling at 70kph survey speed = < 2.5 meter sample spacing.
  • Ground magnetic survey data resolutions without the usual inherent noise that results from magnetite and other magnetic surficial material.
  • Aircraft – bird (sensor) separation, sensor – electronics separation, and bird flight stability results in the cleanest magnetic data available on the market.
  • Ultra high resolution magnetics and orthomosaic photography/DSM data together gives the ability to actually look at and explore surface and outcropping features initially before going into the field.   
  • Simple logistics and VTOL aircraft means fast and inexpensive mobilisation with no need for an airstrip, a large cleared helipad, or delivered and voluminous fuel. Aircraft, fuel, crew, and all survey equipment mobilised to the field base in a single 4WD light vehicle, or alternatively on a commercial airline.
