Third In New Series Of

Navigational Satellites

Launched Into Orbit

The third in a new series of navi- gational satellites for the Global Po- sitioning System (GPS) was suc- cessfully launched into orbit from

Cape Canaveral, Fla., on a U.S. Air

Force Delta II rocket.

According to Magnavox Ad- vanced Products & Systems Compa- ny, Torrance, Calif., a leading man- ufacturer of GPS user equipment, this was the third production-model

Block II satellite to go into orbit this year. The Block II satellites are sup- plementing the existing partial con- stellation of six operational proto- type Block I satellites.

Eventually, there will be 21 active satellites in the Global Positioning

System, providing constant updates in real-time of geographical location for ships, aircraft, land vehicles and even individuals. It will be used by

U.S. and allied military forces, and also, in a slightly less accurate form, by civilian users.

According to a "White Paper" issued by Magnavox, there should be enough Block I and Block II sat- ellites in orbit to provide worldwide uninterrupted coverage for surface navigation by mid-1991.

Magnavox Advanced Products &

Systems Company is a leading man- ufacturer of GPS navigational equipment. The company offers a full family of GPS products, includ- ing extremely precise survey-quality systems, military systems and gen- eral marine GPS navigation receiv- ers. The company reports that there is a considerable demand of GPS equipment, even though full world- wide availability is still more than a year away.
