DGPS
Today, the use of the Differential GPS (DGPS) allows to dispose of metric, centimetric and even milimetric accuracy.
With this system, instrument approaches out of equipped airports can be considered.
In several countries (e.g. USA), DGPS systems allow to highly reduce minima on heliports (COPTER ILS) to 100 ft ceiling and 500 m visibility.
Proteus Hélicoptères works in this way with the implementation of GALILEO, the European challenger of the GPS to provide to its clients services linked to these new technologies.
