Magnetometer Surveys

Drone Geoscience offers Drone Magnetometer surveys using a specifically designed UAV Magnetometer. 

Magnetometer is our Custom UAV MFAM

  • Operating Principle: Laser pumped cesium vapor (Cs133 non-radioactive) total field magnetometer
  • Operating Range: 20,000 to 100,000 nT
  • Gradient Tolerance: 10,000nT/m
  • Noise/Sensitivity: 0.005nT/ Hz rms typical
  • Sample Rate: 1000 Hz. synchronized to GPS 1PPS
  • Bandwidth: 400Hz
  • Heading Error: ± 5 nT (heading error can be effectively reduced to sub 0.1nT by compensation pre flight calibrations)

Typical Survey Characteristics

  • Radar controlled flight elevation (ie Terrain Hugging) from 2 meters AGL to 80m AGL
  • Flight Line separation (as specified by customer)
  • Quotation is on per line km basis, plus Mob/Demob
  • PPK flight line accuracy for flights above 10m AGL
  • RTK flight line accuracy for flights below 10m AGL

Typical Uses

  • Inaccessible Terrain: Difficult or dangerous terrain is our speciality, making it perfect for surveying wetlands, heavily vegetated areas, extreme terrain, or protected lands.
  • Geology: Survey for lithology derived variations in the magnetic field, lower and faster than previously considered possible.
  • Environmental: Find abandoned wells, pipes, and storage tanks quickly and with precise positioning.
  • UXO Detection: The combination of the laser controlled flight elevation and rapid sampling (1000Hz) is the perfect tool to survey sites for detection and delineation of UXO.
  • Archaeology: Survey vast distances and leave potential archaeology sites undisturbed.
