AeroNav GNSS is an entrance level device for mission navigation and camera control based on a fast GNSS AeroStab S is a full compensating 3 axis stabilizer that uses a combined GNSS-INS. It keeps your camera nadir viewing and compensates drift at two modes including planned track. The GNSS is the same type as on the AeroNav products but combined with MEMS gyros and accelerometers with internally Kalman-filtered attitude calculation. AeroStab-S is very agile and can run in 3 modes, depending of the sensitivity of the aircraft. The bi-directional RS232 communication with AeroTopoL FMS supports camera trigger and camera event ma- nagement as well as control of all stabilizer functions in AeroTopoL and writing report files with all orientation parameters.
