Distinguishable features
GEMS is a 2-camera standalone low SWAP UAV subsystem. It allows any UAV or Remote Controlled, fixed wing or rotory vehicle, to fly and collect precision camera imagery. The sensor payload is completely standalone and provides precision navigation and GPS data. The system integrators dream-just plug it in and fly! Does not need integration with external sensors to mosaic images. Provides mosaiced RGB, NIR, and NDVI aerial imagery.
