GEODEVICE - Model AeroSmartMag -Overhauser drone magnetometer

Easy-to-Use Drone Magnetometer
AeroSmartMag has a simple field console: select parameters, press Start, and continue flying — no operator input needed for up to 5 hours.
All data is stored on the internal microSD and downloaded via USB to PC or smartphone.

The controller includes:
OLED display (−40 to +60 °C)
Backlit keypad
Built-in multi-band GNSS with RAW data logging

Optimized for UAV Work
The foldable frame reduces transport size and also absorbs impact if the drone lands hard.
Most structural parts are 3D-printed → if a part breaks, we can send you the model, so you can print the replacement locally.

Power & Autonomy
Up to 5 hours of continuous measurement with the included lightweight battery.
For base-station or GNSS-only operation, a larger external battery can be connected.

Data Format
Data is stored in project folders. Each flight session is saved as a TXT file with a name that includes:
- Console serial number
- Measurement mode
- Number of sensors

Each measurement is one line containing: UTC time, flight or base name, total field, estimated error, sensor ID, latitude/longitude, altitude, UTM (auto zone & hemisphere) and GNSS accuracy.
RAW GNSS data is saved in a separate file with the same base name.
This ensures consistent datasets and allows you to identify exactly which instrument collected each flight, even when multiple crews work simultaneously.

High Accuracy in Real Environments
Each instrument is metrologically tested (noise level, absolute accuracy, heading error).
Advanced filters allow reliable surveying in industrial noise environments and near / under powerlines.

Centimeter-Level GNSS Positioning 
The built-in multi-band GNSS with PPK enables cm-accuracy positioning.
AeroSmartMag can also operate as a GNSS base, rover, or tracker.
GNSS RAW data can be converted to RINEX.
Supports NMEA-0183 for external GNSS integration.
