Globalstar satellite phased array antennas

The Globalstar worldwide satellite system will provide voice, facsimile, paging, and data transmission to subscribers with hand-held mobile and fixed services, covering locations in all areas of the world except the far reaches of the Arctic and Antarctic. The complete system is a constellation of 48 three-axis-stabilized satellites located in low Earth orbit at an altitude of 870 miles. The Earth subtends an angle of /spl plusmn/55/spl deg/ from nadir at this altitude. Each satellite weighs about 1012 pounds and orbits the Earth in 114 minutes. Mission life is 10 years, after which the satellite will be raised to a higher orbit. Globalstar is a trademark of Globalstar.
