The system

The integrated system combines a drone with a sensitive magnetometer SENSYS MagDrone R3 and a precise altimeter for True Terrain Following mode.

Typical applications

SENSYS MagDrone is a Fluxgate magnetometer system and therefore is able to detect any magnetic metals/materials. It is applicable to:

Acquired data quality

The magnetometer is not an active sensor. It measures the magnetic field at the point where it is located. So for the detection of objects (especially small ones), it is very important to fly as close to the surface as possible. The true terrain-following system with a precise laser altimeter allows flying as low as 1m AGL.

Main benefit

Using a magnetometer on a drone enables us to scan the area and detect metals several times faster compared with handheld devices and allows obtaining geo-referenced maps of the area.

Flight mission planning

One of the main components of the integrated system, enabling efficient survey planning is UgCS - flight planning software providing tools for easy creation and calculation of flight paths, and interpretation of acquired data in a user-friendly manner.

FEATURES OF THE INTEGRATED SYSTEM

Compact and simply-to-use

MagDrone R3 is a light and compact magnetometer system. Almost any drone with a payload capacity of 1kg can be used. We recommend DJI M600 Pro, M210, M210V2 or medium/large drones with Pixhawk autopilot.

MagDrone R3 has a 200Hz sampling rate, which makes it possible to be attached to the drone’s legs without detrimental effects. A high sampling rate allows filtering out noise caused by the drone’s motors and electronics. This is a huge benefit compared with traditional magnetic sensors that are attached with a rope under a drone, especially for inexperienced drone pilots.

Integration with the drone

Power for the MagDrone R3 is provided from the drone's main battery eliminating the need to have one more set of batteries in the field.

Easy to use software to process the data

MagDrone R3 comes with the SENSYS DataTool software.

The DataTool software has 4 main functions:

The preview window allows to access collected magnetic data in seconds without having to deal with complex geophysical software:

For further processing and visualization, we recommend SENSYS Magneto or Geosoft Oasis Montaj – or any other software capable of importing and visualizing geotagged scalar data.

Laser altimeter for automatic terrain-following

The amplitude that the magnetometer is measuring decreases by the 3rd power of the distance. Below are samples of data gathered from the same area using different flight altitudes. There are 2 pieces of metal pipes (with a diameter of 2 inches and 1 inch) hidden underground.

The preview was generated with SENSYS MagDrone DataTool, and the 3D surfaces were created using Geosoft Oasis Montaj. The vertical scale is the same on all 3D surfaces.

The dependence of the amplitude of measured values on the distance is clearly visible in these samples.

UgCS True Terrain Following with laser altimeter allows flying in automatic mode as low as 1m AGL providing a possibility to detect small objects and gather high-resolution data.

UAV integrated system in action

Metal detection with magnetometer integrated with a drone

The UAV integrated system combines a drone with a sensitive magnetometer and a precise altimeter for True Terrain Following mode. The survey mission of the drone-based magnetometer is planned with UgCS.

UgCS True Terrain Following

Adding the UgCS SkyHub and an altimeter to the integrated UAV system will allow planning drone's flight missions with UgCS in True Terrain Following mode. UgCS SkyHub Data-sheet & User Manual

The True Terrain Following allows the drone to accurately follow the terrain during the flight, based on data received from the laser altimeter. True Terrain Following enables the drone to fly at low altitudes (up to 1meter) without a need to import precise Digital Elevation Model (DEM) height-map into UgCS

One of the main components of the integrated system, enabling efficient survey planning is UgCS - flight planning software providing tools for easy creation and calculation of flight paths, and interpretation of acquired data in a user-friendly manner.
