Back to the stars
Abstract
The use of man-made stars, or satellites, in navigation systems is discussed. Cost estimates for terrestrial radionavigation systems and for a global independent civil navigation satellite are compared. A transition from terrestrial systems to total dependence on satellite navigation systems is discussed. Potential savings to users are outlined. The features that a global independent civil navigation satellite system would need to have are identified. These include global coverage, very high integrity and guaranteed global access. Introduction of a civil overlay to eliminate the weaknesses of the military systems presently under deployment is discussed.
