Ultra-sensitive airborne integrated magnetometer system powered by QuSpin QTFM Gen-2 atomic total-field magnetometer sensors

Typical applications are:

  • Searching for UXO (unexploded ordnance) and landmines in metallic casings
  • Tramp metals and lost GET (ground engagement tools) detection
  • Locating buried infrastructure (metal pipes and shielded cables)
  • Environmental surveys for abandoned wells, pipes, and storage tanks quickly and with precise positioning
  • Geology and minerals prospecting: surveys for regional variations in the magnetic field
  • Archaeology

Self-foldable sensor mount allows easy take-off and landing without excess requirements for drone operator qualification as it is for magnetic sensors on suspension cords.

System variants

MagNIMBUS comes in two possible configurations:

  • Gradiometer. This configuration simplifies data processing and makes magnetometer base station not necessary. Additional benefit – gradiometer makes possible magnetic surveys in proximity to the sources of EM fields like powerlines.
  • Configuration with single sensor with foldable mount. Detection capabilities are the same as for gradiometer setup, but requires more experienced specialists for data processing, magnetometer base station is recommended in some cases.

UXO/landmines detection note

The system is capable to detect a range of items starting from hand grenades (the estimated sensor-target distance for detecting an object such as the F1 hand grenade is 0.5 m) till big UXO like aerial bombs at the distance of few meters.

While magnetometers can detect some types of landmines (for example M15, M6, TM-62M anti-tank mines; M16, PROM-1, OZM-3, OZM-4, OZM-72 anti-personnel mines and similar types with considerable amounts of ferrous metal), landmines search is not a direct application of magnetometers as they can’t detect most types of modern landmines. That means that the system never should be used to confirm absence of landmines (and small ordnance) in certain area but it can be valuable asset during Non-Technical Survey (NTS) or Technical Survey (TS) to confirm presence of UXO/landmines with considerable amount of ferrous metals.
