“With about 500 people on the set, precision was key to make sure we fly exactly in the area that was planned” – said Emmanuel Prévinaire, founder of Flying-Cam
Each video frame was time stamped with GPS time and then geotagged with RTK centimeter-level positioning and camera orientation angles, which in turn allowed the graphical effects team to add in the flying dragon precisely as planned. The combination of computer animation with a real background and a real person made the whole scene come to life.

Mission Impossible 6 – Photogrammetry in the heart of Paris
Flying-Cam’s helicopter also had a role to play alongside Tom Cruise in Mission Impossible 6. The film’s visual effects team needed a detailed 3D reconstruction of the Grand Palais. This meant a photogrammetry flight in the center of Paris less than 500 m (547 yd) from the Presidential Élysée Palais.
A challenge arose when the Flying-Cam’s team spotted significant magnetic interference coming from the subway below the street where their helicopter was standing for take-off.
“The only way for us to take off in that location was with the use of Septentrio dual GPS antenna on board. Thanks to the heading solution and precise positioning, we could take off and fly out of the magnetic disturbance.” said Emmanuel Prévinaire “We also witnessed very clean positioning during the whole 3 hours timeslot, which was key for geotagging more than 1000 images taken during this photogrammetry flight. “
Georeferencing and navigation solutions anywhere
Navigating a precise flight-path on a movie set, accurately georeferencing photogrammetry data or other industrial flight missions rely on high-accuracy GPS / GNSS positioning and orientation information. Septentrio AsteRx-i receiver combines centimeter-level RTK positioning with precise 3D orientation from a high-grade MEMs IMU (Inertial Measurement Unit). Advanced Interference Mitigation (AIM+) technology shields the receiver from internal or external interference. Accompanied by a UAS-tailored carrier board it can be integrated seamlessly into your aerial vehicle. Who’s up for a “Game of Drones”?
