Towards Drone-borne Gammaray Surveing

Recently we finished a first series of flight tests of our “drone-borne” gamma-ray sensor. To answer to the increasing demand for drone-borne sensing systems, we decided almost a year ago, to start the development of a lightweight and rugged version of our gamma-ray detection systems; the “drone detector”. The aim of the project is to […]

Underwater mapping of sediments

In recent years, laws and regulations in the field of ecology became more strict due to public pressure. Therefore, the discharge of fines during dredging and land reclamation works and its impact on seafloor habitats is an important aspect in environmental impact assessments.

Multi sensor system for farmland in Spain

To increase the (financial) yield of Spanish farmers on low-yielding rainfed soils, a EU LIFE+ project ‘Crops for better soil’ was initiated. The aim was to improve the soil itself by applying several agronomic measures and by better understanding the soil. To this purpose Medusa developed an efficient and effective soil sensing system on a […]

A rugged gamma-ray spectrometer on a TEM frame

Airborne gamma-ray surveys (GRS) have been routinely applied for decades to map the earth’s surface. Recent advancements in computing power and detection technology have significantly improved and it is now possible for gamma-ray systems to be manufactured more compactly, rugged and light-weight. These next generation gamma ray spectrometers open boundless opportunities to use these systems […]
