Symphonie 1

NSSDCA/COSPAR ID: 1974-101A

Description

Symphonie 1 was a French-German, geostationary, equatorial, experimental communications satellite. The satellite body was a right hexagonal prism, 1.85-m maximum diameter and 0.5-m high. Several antennas and other appendages were mounted on the ends, and three sets of symmetrically placed solar panels extended outward a distance of 2.6 m from alternate edges of the spacecraft. A flywheel operated attitude control system maintained attitude along three axes. A positive orbit control system placed the spacecraft near 11.5-deg w longitude and was used to maintain that position. It provided 1200 phone channels and two color TV (including eight voice) channels which operated between 4 and 6 GHz. It was used for communication between Europe, Africa, South America, and the East Coast of North America.
