The original motivation for satellite navigation was for military applications. Satellite navigation allows precision in the delivery of weapons to targets, greatly increasing their lethality whilst reducing inadvertent casualties from mis-directed weapons. (See [[Guided bomb]]). Satellite navigation also allows forces to be directed and to locate themselves more easily, reducing the [[fog of war]].

Now a global navigation satellite system, such as [[Galileo (satellite navigation)|Galileo]], is used to determine users location and the location of other people or objects at any given moment. The range of application of satellite navigation in the future is enormous, including both the public and private sectors across numerous market segments such as science, transport, agriculture, etc.<ref>{{Cite web|url=https://www.gsa.europa.eu/galileo/applications|title=Applications|date=2011-08-18|website=www.gsa.europa.eu|language=en|access-date=2019-10-08}}</ref>

The ability to supply satellite navigation signals is also the ability to deny their availability. The operator of a satellite navigation system potentially has the ability to degrade or eliminate satellite navigation services over any territory it desires.
