Civil-military navigation

Challenges for the military

The need for enhanced civil-military interoperability in the navigation domain is of the utmost importance, especially when flights are conducted in mixed-mode environments in controlled airspace.

Although military operational requirements with regard to positioning, navigation and timing are already met, the increasing influence of civil navigation requirements needs to be taken into account when State aircraft are flying under General Air Traffic (GAT) rules.

The main aspect impacting civil-military navigation interoperability will be a transition from equipment-based certification to an alternative process based mostly on equivalent required navigation performance values.

In this sense, close cooperation between the civil and military organisations responsible for the provision of navigation services is a clear objective in the following domains:

  • Performance Based Navigation (PBN) concept and military performance-based solutions
  • Performance-based certification of military airborne systems
  • Relative navigation using military data link
  • Reduced Vertical Separation Minima (RVSM) solutions
  • 4D Navigation
  • Navigation infrastructure rationalization

Transitional arrangements and exemptions will have to be defined and agreed in order to cope with lower-capability military airframes. All innovative approaches must therefore be considered, including lost-cost solutions with regard to the considerable expense of military aircraft retrofits.


How we help

On the basis of the work scheduled and ongoing in the SESAR Programme, EUROCONTROL has a clear and key role in providing guidance to military stakeholders, taking account of the specificity of their needs in order to achieve a seamless civil and military approach in the navigation domain when preparing for the 2020+ timeframe.
