Until now, only a few naval and scientific vessels used the Transit system, largely because the shipboard equipment is so expensive. Custom-built, each receiver costs between $21,000 and $35,000 ...

Scrounged Parts. Only one satellite is needed for an accurate navigational fix, but when the Navy’s system is operational in 1962, four satellites will crisscross in a synchronization planned to ...

Backup Transit 5-A satellite from the 1970s. National Air and Space Museum, Smithsonian Institution photo. “For TRANIST fixes, we had to go to periscope depth and raise a special antenna.

A terrestrial observer’s unknown location could be derived from the known orbit of a single satellite. That idea turned into the first satellite navigation system. In 1964, the Navy Navigation ...

But the first automated in-car navigation system was developed long before we had the technology to put anything into space. The concept of the modern navigator can be traced back to the early ...

1959 The Navy built the first real satellite navigation system, which it called TRANSIT. The system was designed to locate submarines, and started out with six satellites and eventually grew to ten.

In the late 1950s, they began developing and testing satellite navigation technology, and the U.S. Navy deployed the operational Transit satellite system in the 1960s.

On This Day in History; 13 April 1960: the first satellite navigation system is launched. On this day in 1960, Nasa sent the Transit 1B satellite into orbit to provide positioning for the US Navy ...

Apple has a couple of new patent application with the USPTO (via AppleInsider) that details what could be its solution for providing transit directions.
