OVERVIEW
After extensive testing, Flightec introduced a UAV based Magnetometer Survey solution in 2020. The core component is a Geometrics MagArrow which allows samples to be taken every centimetre at a flight speed of 10m/s while a magnetic base station records diurnal variations. The MagArrow is the first ever 1000Hz UAV-enabled magnetometer and Flightec is one of a limited number of companies offering its services.
The MagArrow sets a new standard for UAV Magnetic Surveys with:
- Operating Principle: Optically pumped Caesium Vapor
- Operating Range: 20,000 to 100,000 nT
- Gradient Tolerance: 10,000 nT/m
- Sample rate: 1000Hz, GPS synchronised every second
EXECUTION
A Drape survey is executed at a fixed distance to the terrain while adhering to aviation safety standards by maintaining a minimum clearance from hazardous objects. The flight path is tailored specifically to the selected UAV’s flight envelope, ensuring smooth profiles over undulating terrain and through turns.
UAV Benefits:
- Smooth Profiles
- Precise Clearance
- Fully Autonomous
- Minimal Sensor Oscillation
- Minimal Line Deviation
- Parallel Scalability
