ARIEL L-band microwave radiometer

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

Applications

Agriculture / Environment
  • Soil and soil moisture variability
  • Puddle detection with vegetation cover
  • Irrigation planning
  • Land management
Civil Engineering / Minning
  • Levee inspection
  • Tunnel and galleries inspection
  • Surface moisture in linear infrastructure
Other
  • Earth Observation, validation of satellite data
  • Telcomm, location of sources of electromagnetic interferences
  • Thin sea ice thickness studies

SMIGOL

L-band GNSS reflectometer

For local constant monitoring and sensor networks

This sensor can be understood as a bi-static radar where the GPS satellite is the emitter and SMIGOL the receiver. SMIGOL analyzes the difference between the signal received directly on the sensor and the one reflected from ground to the sensor. The difference between these two signals can be used to obtain soil related measurements.

Advantages

  • Soil moisture and altimetry measurements
  • Data is obtained through non invasive methods: not interfered by animals nor ground vehicles.
  • To be installed on a pole. Area covered: three times pole height
  • Fully autonomous: fed by solar panels, and data transmitted via GPRS receiver.

Applications

Agriculture / Environment
  • Local soil moisture
  • Irrigation planning
  • Vegetation heigh
Civil Engineering / Minning
  • Levee monitoring
  • Water level measurement
