ARIEL L-band microwave radiometer
Description
For large extensions and mobile platforms
ARIEL is a microwave radiometer that can be used for soil moisture remote sensing. It is based on the same technology used by the instrument MIRAS on-board the ESA SMOS satellite mission.
Advantages
- Large extension can be covered without requiring infrastructure
- Configuration through web-based user interface
- To be used on board aircrafts, drones, and ground vehicles.
- Compatible with most common GIS software
ARIEL series
Applications
