This manual describes ZBA9310, the Navstar 60S Transit Satellite Navigator, made by Navstar Systems in 1985. The device worked with the Transit satellite system to determine a user’s latitude and longitude. The Navstar 602S is an early example of a satellite navigation receiver manufactured for non-military marine markets including fishing and commercial. The Transit satellite system became operational in 1964 and the technology was later made available to civilians and the commercial market. By the 1980s, navigators working on thousands of warships, freighters and private watercraft used the Transit system. This was partly due to changes in how consumer electronics were manufactured and advances in chip technology. The manual is sectionalized to cover the basic user requirements from a brief explanation of Satellite Navigation, the ‘Transit’ System, and the NAVSTAR 602S from Installation (includes Calibration, Test and Initialization) to Operation. 130 pages. Paper and spiral bound.
