On Intelsat V proposals
Continuing a precedence of international subcontracting for high technology space programs, Space and Communications Group announced it has incorporated proposals from subcontractors around the world in the competition for the Intelsat V series of global communications satellites proposed for the 91-nation Intelsat organization.
The Group has submitted two independent spacecraft proposals to the Communications Satellite Corporation (Comsat), management services contractor to Intelsat. One is for design, development, and manufacture of a spinner type spacecraft, the other for a three-axis body stabilized type. A contract award is expected to be announced later this year.
Vice President Albert Wheelon, Group executive, said the proposals are responsive to Intelsat’s desire for international participation on the new communication satellite series, planned to meet global telecommunications requirements through 1985.
“To this date we have issued over 140 requests for proposal to 23 subcontractors in ten nations, and responses to these solicitations have been received,” he said.
International companies and their scope of work included in the two Hughes proposals are:
Canada—Bristol Aerospace Ltd., filter components; Northern Electric Company, basic elements for the 6/6 GHz communications subsystem, power electronics and telemetry/command digital units.
France—Thompson-CSF, elements for the 6/4 GHz and 14/11 GHz communications subsystem plus 11 GHz traveling wave tubes.
Germany—Teldix, momentum wheels; Telefunken, elements for the 14/11 GHz communications subsystems and additional 11 GHz traveling wave tubes.
Italy—Selenia, antenna efforts associated with the 6/4 GHz and 14/11GHz communications subsystems.
Japan—Nippon Electric Company, traveling wave tube amplifiers and portions of the 14/11 GHz communications subsystems.
Spain—CESCA, basic electronics units.
United Kingdom—British Aircraft Corporation, work associated with structures, wire harnesses, battery packs, and solar cell arrays; Pilkington P.E. Ltd., solar cell cover slides.
The above international subcontract effort will exceed $25 million for the initial buy of seven spacecraft of either the spin stabilized or body stabilized configurations. Active reviews of additional international offerings are continuing, Dr. Wheelon added.
Citing the number of highly skilled companies throughout the world that have participated in the past with Hughes in successful spacecraft development, he said 13 individual subcontractors in 10 countries have supplied equipment now operating in space.
“This direct experience with Hughes was initiated in Intelsat II, extended on the Intelsat IV and IV-A Programs, and has been augmented in the Canadian domestic Anik satellite, Western Union’s Westar, Comsat General’s Comstar, and the Republic of Indonesia’s Palapa Program, all of which involve significant non-U. S. subcontracting,” Dr. Wheelon said.
“All of the work involved more than $64 million of successful international subcontracting on long-life communications satellites.”
