Multi-frequency GBSAR
Balamis Multi-frequency GBSAR is a flexible Ground-Based Synthetic Aperture Radar for slope stability and structures monitoring. It targets customers and researchers who have to deal with complex stability studies where vegetation or snow cover difficult proper measurements. The use of multiple frequency bands assists the compensation of atmospheric artifacts, vegetation and/or snow cover and moisture presence.
It is also an optimal tool for ground truth and preparation of future satellite mission providing hiper-temporal multi-band data of current and future space-borne SAR systems.
Advantages
- Constant monitoring fully autonomous
- Displacement measurement by remote sensing
- Long range measurement, up to 4 km
- Compatible with most common GIS software
Applications
Civil Engineering / Minning
- Tailing dam monitoring
- Slope stability
- Structural monitoring
Agriculture / Environment
- Geohazard prevention and mitigation
- Support to the validation of forestry and moisture models
Other

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
