Beskrivning : This satellite is designed to provide a navigation reference and the means for its use by a passive user.Timation proved that a system using a passive ranging technique, combined with selected high-performance crystal oscillator clocks, could provide the basis for a new and revolutionary navigation system with three-dimensional coverage (longitude, latitude, and altitude) throughout the world. NCST`s Timation program paved the way for what eventually became the Global Positioning System (GPS).
