The GDS provides documentation and traceability via the internal Video and HD Cameras. Designed and engineered by Breault Research Organization (BRO), the GDS uses a sample of the gas of interest as a spectral filter.

Two radiometers — one with gas (correlation) cell in its optical path and the other without — focus on the ground through a narrow spectral absorption band (passband). The radiometer without the correlation cell, measures the total incoming radiance / flux within the passband (REF signal).

The radiometer with the correlation cell also measures incoming radiance / flux within the passband at the COR signal. By comparing the REF and COR signals, gas concentrations are retrieved. On-board cameras take pictures of the scene and sensors measure location and flight relevant data.

• ipeline Inspection
• Leak Detection
• Ethane and Methane Detection
• Hydrocarbon Detection

Designed to operate at 300-meter AGL, the sensor mounts vertically in a standard propeller aircraft and views the scene below.  The system passband is between 2-3 microns.  Ground resolution is 200mm.

Each radiometer includes features to optically match magnification and reduce parallax to within a pixel.  Data is stored in a Data Power Management system for post analysis.
