• Airborne GPS Controlled Mapping

Large scale mapping and photogrammetric projects have used GPS technology to economize the cost of ground control.

Airborne GPS (ABGPS) greatly reduces the amount of costly ground control. By adding a precise GPS receiver to the aircraft and one or more base receivers occupying known control points on the ground, precise photo center coordinates can be obtained.

ASC supports your mapping project with Airborne GPS, collection of data, and processing of photo centers.
