PHYSICS OF GPS

Newton's First Law

•An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force

Gravitational force

Gravity is continually pulling the satellites down around the earth

The satellites are in a constant free falling state

Electromagnetic waves

Electromagnetic waves do not need a medium to travel through, allowing them to move in a vacuum

This makes these waves perfect for sending data to and from space

NAVTOOLS ROUTE is a complete route planning application. Unlike any other similar application. NavTools Route is able to calculate the most economical engine rpm setting to reach your destination on schedule, taking into account average or predicted weather along the route (data will include wind speed and direction as well as wave heights and current). Many handy tools are included.

THE HISTORY OF GPS

Beginnings in WWII

LORAN and Decca Navigator

Used to guide ships away from shorelines

Heavily used by the Navy during WWII

Developments in the 60’s

Transit and Timation Systems Transit is the first satellite navigation

system also used by the Navy

US Navy develops Timation satellite that proved the ability to put accurate clocks into space

GPS relies on this technology

Movement toward GPS

Cold Arms Race helped justify spending the money for research and development of GPS

US Navy and Airforce jointly work together on their missile systems

Enabled them to pinpoint their location prior to launch

1973 military officials at the pentagon agree on a single superior system Navstar, later known as GPS
