UAV Magnetometer R4-M350 – High-Resolution Mapping
R4 is an ultra-portable magnetometer designed for surveys over large areas when conventional ground-based configurations by people or vehicles are no longer possible: in these cases, the drone represents the best solution both in terms of production and operator safety.

Advantages of using UAV systems:
– Reduced human risk thanks to autonomous data collection
– Access to the entire network regardless of ground conditions or obstacles
– Continuous data acquisition enabling identification of critical points such as underground structures, pipeline crossings, parallel lines, or metallic objects
– 3 times faster acquisition speed than traditional tools, reducing inspection time and cost

The R4 magnetometer can also be configured with a handle and GNSS receiver for ground-based use by the operator and in a gradiometric configuration to improve data resolution.

The operation of UAV Magnetometer R4-M350 is simple. It has only one button and an integrated server accessible from any WIFI device, such as smartphones, tablets, or laptops. In addition, the flight altitude is managed by the programmable True Terrain Follow (TTF) from the “Mission Planner,” an automatic mission planning system. This facilitates configuration, system verification, remote start/stop of recordings, and data download. The provided software helps identify flight paths, cut, filter, and compensate raw data, generates a preview, and exports in various formats for further processing of recorded values, such as using GIS tools or Matlab with custom scripts.

Data Compensation Base
Using a reference station, the magnetic data acquired with the drone can be correlated with that of the Base. This will enable the elimination of temporary noise sources such as crossing vehicles, network frequencies, or solar storms.
