The Global Positionning System (GPS) really revolutionized number of applications for which it is important to know where we are.
It is the case of the navigation (ground, maritime and aerial), but also of a many operations of collection of information, logistic support, etc.
We developed a long experience of the usage of the GPS, because we began to use it in 1990, even if the system was completely operational only in 1995.
We use in a regular way GPS systems for the collection of information and for the navigation (in particular during the aerial photography missions).
We also developed an expertise in the use of differential GPS solutions, allowing a better precision.
