Radai operates a high-performance magnetic survey system built on fixed-wing VTOL drones. With flight times over two hours and simultaneous use of multiple drones, 1 000 line-km can be reached in a single day.
Our VTOL drones are equipped with a lightweight Radai TMI system that comprises Geometrics MAFM sensor and Radai multipurpose (RMP) datalogger providing 32-bit data with 50 fT resolution and 1000 Hz sampling rate.
The system provides high-resolution total magnetic intensity (TMI) data for mineral exploration and geological mapping — delivering reliable results even in the most challenging environment. Fast deployment and precise anomaly detection make it a powerful tool for modern geophysics.
