Transit (satellite)
The TRANSIT system, also known as NAVSAT (for Navy Navigation Satellite System), was the first satellite navigation system to be used operationally. The system was primarily used by the U.S. Navy to provide accurate location information to its Polaris ballistic missile submarines, and it was also used as a navigation system by the Navy's surface ships, as well as for hydrographic and geodetic surveying. Transit provided continuous navigation satellite service from 1964, initially for Polaris submarines and later for civilian use as well.

Famous quotes containing the word transit:
“My esoteric doctrine, is that if you entertain any doubt, it is safest to take the unpopular side in the first instance. Transit from the unpopular, is easy ... but from the popular to the unpopular is so steep and rugged that it is impossible to maintain it.”
—William Lamb Melbourne, 2nd Viscount (1779–1848)
