The 3550 is a miniature version of the 3500 in a compact 2"x1" form-factor. The 3550 includes on board AHRS and airdata sensors and comes with a pre-wired GPS & radio-modem. Advanced features include real-time waypoint control and track display on a high resolution map image. The 3550 was specifically designed for small, commercial UAVs and MAVs (small electric fixed-wing aircraft). The 3550's feature set supports proposed FAA guidelines for Group II sUAS operations. The autopilot is capable of operating in all weather, all terrain and on all fixed-wing aircraft.
