This is an operating manual produced for (ZBA9314) Navstar 2000 Series: Satellite Navigator. Manufactured from 1987 to about 1993 by Navstar Systems, the Navstar 2000S worked with the Transit satellite system to determine a user’s position and speed. Sold as part of the Navstar 2000 Series, this was the final and lowest cost Transit SatNav produced by Navstar Systems. The ‘Navstar 2000 Satellite Navigator’ was often sold and used with either the Navstar 2000D Decca Receiver (see ZBA9317) or the Navstar 2000L Loran Receiver (ZBA9316). Together, the three receivers cover a range of position-fixing technologies used by mariners in the period 1987-1993.
