Formed in 1990 by qualified Surveying Engineer Bertrand BOULLARD TopoSat® provides services focusing on the use of GPS/GNSS positioning techniques. It was one of the first in France to practice in this field when this technique was born in the 90s and remains one of the few to make it its main activity.
It works in the field for skate out or topographic survey work and also provides short training in conventional topography and GPS. It participated in the implementation of several CORS networks, in particular in Africa. She provides assistance and advice for writing SOW (topography works)
We operate throughout France and in the World.
Thanks to its lightweight structure, TopoSat® offers fast and flexible responses to all requests in its scope of expertise. We can also call on our informal partner network in France and various countries worldwide for support in case of large requirements in terms of personnel or equipment.

This activity can only be carried out under the cover of a Particular Activity Manual. Its writing is complex and specific to each company. We only put one online an extract and have a printed version that we keep available to the competent authorities and to our customers during flights.
It is important to specify that the topography services by drone fall under two separate and complementary insurances covering the civil liability linked to the topographic service for one and that linked to the flight of the drone for the other.
