The unmanned aerial system with a gamma-ray spectrometer for geological surveys.
UAS Geoscan 401 Gamma with a gamma-ray spectrometer
The Geoscan 401 Gamma system is designed for gamma-ray spectrometric surveying and generating maps that show the secondary radiogeochemical zonality, the exposure rate, the concentration of potassium, uranium and thorium. The UAS can take off from a 5 m radius site, operate within confined space and accurately bend round terrain. It carries the gamma-ray spectrometer GS-1.
Due to its low weight and high sensitivity, the gamma-ray spectrometer, designed by the Geoscan company, allows to conduct aerial and gamma-ray spectrometric survey with the UAV.
You can purchase the gamma-ray spectrometer GS-1 separately or as a payload for Geoscan 401 Gamma.
It is much easier, quicker and cheaper to organise gamma-ray spectrometric survey with an UAV than with a plane or helicopter. Research outcomes allow to determine locations that may be interesting to explore and, thus, to reduce the amount of unproductive exploratory drilling.
A survey provides accurate data on the concentrations of chemical elements. The results allow to correct properly further development of geological surveying.
Specialized well-adjusted autopilot developed by Geoscan arranges customer’s tasks fulfillment requiring no alignment or refining. Software makes operation easy and safe.
Manoeuvring system follows any complicated route providing accurate bending round the terrain and steers the course even at wind speed 12 m/sec in fully-automatic mode.
Vertical launch and landing make drone suitable for using in a tight city space or in a thick forest. Smart battery covered with special shell guarantees fail-safe operating at temperature range from – 40 to +40 °С (arctic option).
