GREAT – GNSS REflectometry Artificial intelligence-enabled Test-bed

GREAT aims to develop and validate an innovative GNSS Reflectometry (GNSS-R) airborne test-bed as a precursor to the first Italian space mission in this field. Through dedicated flight campaigns over land and sea, the project targets enhanced environmental and territory monitoring with high spatial resolution. GREAT will deliver key geophysical products such as sea surface wind, soil moisture, biomass, and marine altimetry. The integration of AI on-board processing and GNSS-R/SAR techniques will enable near real-time data exploitation for applications in civil protection, meteorology, and agriculture.

  • Funded by Italian Space Agency (ASI)
  • Developed by proposed by a consortium including TASI, Unisannio, CNR-IFAC,  GEO-K, Uniparthenope, UniNA (Federico II), Intecs Solutions, MAPSAT, AizOon

DronEM (Drone for Electromagnetic fields Measurements)

/in , , /da

The collaboration between GEO-K and MPB Group allowed the design and implementation of a novel technique for 3D measurement and mapping of Electro-Magnetic field distribution.

DronEM permits the estimation of EM pollution and the creation of pollution maps, as well as the verification of signal quality and cover. The system consists of a Drone equipped with a Selective Electric Triaxial Probe (SEP) and is able to scan the electromagnetic spectrum between 10 MHz and 3 GHz, till 200 m altitudes.

This UAV+SEP technique allows a precise monitoring activity and the possibility to plan automatic missions at different flight heights with high accuracy.
