Threats to satellite navigation systems
Network Security, 2015Global Navigation Satellite System (GNSS) solutions are everywhere now. The capabilities of what many people loosely term GPS can be found not just in cars and aircraft, but are increasingly being integrated into many portable devices and are a key function in the Internet of Things (IoT).

The Navigation of a Communication Satellite
Journal of Navigation, 1963The navigational aspects of the requirements for a medium altitude satellite communication system are discussed. Twelve satellites have to be injected into a circular equatorial orbit with very great precision. It is not practicable to navigate the launching vehicle accurately enough to obtain the correct orbit at first injection and the satellite ...

Use of satellites for navigation
IEEE Transactions on Aerospace and Electronic Systems, 1968Any position on earth can be determined as the intersection of two circles, with their centers located at 0 and 0' on the earth's surface just beneath two satellites. Therefore any flying path can be described as a locus of many such positions. One synchronous satellite can cover 45 percent of the surface of the earth.
