                9.10.2.7     Aviation regulations regarding GNSS systems


                ICAO  establishes  standards  and  recommendations  for  the  use  of  GNSS  in

                aviation. This includes requirements for precision, accuracy and redundancy.


                EASA Implements specific procedures for the use of GNSS in aircraft operations,
                including approval of navigation systems and training of pilots.

                9.10.3    GPS


                In Denmark, aircraft primarily use GPS as a GNSS system.


                GPS stands for Global Positioning System.




                It  is  an  American  satellite

                navigation  system  based  on

                approx. 24 satellites used agt
                in  orbits  approx.  20,000  km

                above the earth.











                The first GPS satellite was launched in 1978. The system is controlled by the US

                Department of Defense and was used for precision attacks with missiles, etc.


                The US has the ability to influence the accuracy of the system and can in theory

                shut down its use.

                The GPS system is the name associated with the American NAVSTAR system

                (Navigation Satellite Time and Ranging).
