    Global-navigation Satellite Systems (GNSS) provide navigational data to airborne transportations and various other applications. Mainly two satellite constellations are in use today for navigational purposes. They are global positioning system (GPS) which is provided by the United States and global navigation satellite systems (GLONASS) which is provided by the Russian federation [1]. GPS and GLONASS satellites fly in medium Earth orbit (MEO) at an altitude of approximately 20,200 km and 19,100 km

    To understand where the Global Positioning System first began we have to go back to the time of the Cold War. It was in 1957 when the Soviet Union launched the first ever man made satellite into orbit. This satellite was launched as a demonstration of technological advancement and strength over the U.S. What the Soviets least expected was that two Americans would soon find this satellite essential in the discovery of an amazing new technology. Two physicists by the name of William Guier and George
