GHGSat-AV – Aircraft Sensor

Airborne High-Resolution Methane Monitoring

In addition to our planned constellation of satellites, a high-resolution airborne sensor is commercially available. Aircraft monitoring, which provides much higher resolution because it is deployed significantly closer to the ground, is offered as a complementary service to GHGSat satellite monitoring in high-risk areas or in regions with a larger density of sites.  GHGSat is the only company in the world that can offer satellite and aircraft monitoring as a single service for customers.

The instrument is installed in a small fixed-wing survey airplane, with future plans for drone operations.
