Geoscan

Unique unmanned system for aeromagnetic surveying with quantum magnetometer.

Overview

The aeromagnetic system Geoscan 401 Geophysics combines benefits industrial quadcopter Geoscan 401 and quantum magnetometer with rubidium magnetic field sensor.

This UAV complex allows operation at low altitude as in flat terrain and complicated landscape conditions.

With Geoscan 401 Geophysics complex you can measure a magnetic field using a multi-elevation survey. New data analysis method allows creating the hight level of fidelity for geomagnetic models.

UAV survey method is most useful for mid-sized areas from 10 to 500 km2. At this point, this method is profitable if compare with manned aviation (planes, helicopters) and saves time the survey.

Method efficiency

Aeromagnetic survey is usually performed at 36 km/h (10 m/s) and at altitudes from 25 to 500 m. Max flight time depends on multiple conditions, and usually is close to 1 hour. This is enough to perform 22 km of survey routes including necessary manoeuvres.

Max deviation from planned flight route is 0.6 m. Using spare batteries makes possible to perform 12-16 flight in one day, which results in 160-220 km surveyed.

Route length

Max. flight route length
Up to 220 km in 1 day

Geoscan magnetometric system

Combines key advantages of autonomous UAV and quantum magnetometer with rubidium sensor. It can perform a precise aeromagnetic survey at extremely low altitudes in any terrain conditions due to proximity relief-follow flight.

With Geoscan Geophysics system you can explore volumetric parameters of magnetic field. This is possible using altitude-differential survey and vertical profile calculation. New data analysis and interpretation methods allow creating geomagnetic models with breakthrough authenticity level.

Survey experience in Kazakhstan

Geoscan Planner

Control without RC transmitter

Geospan Planner software allows to create flight missions for areal surveys of terrain and linear objects in different flight modes (point-by-point, areal survey, etc.). You can easily switch different base maps, upload your own maps, terrain models and photo plans to kml. or kmz. formats.

The software will automatically generate flight mission, send flightpath to UAV and track real-time flight status. All you need is to select the area on the map or upload your flightpath.
