SBS-A, the first in a series of three commercial service communications satellites, is scheduled to be launched on a Delta 3910 vehicle from the Eastern Space and Missile Center (ESMC) no earlier than November 12, 1980. The launch support for this mission will be provided by NASA, on a reimbursable basis, to SBS, a consortium of IBM, Comsat General, and AETNA Insurance, at a fixed price of $22.0M. The launch of SBS-B on Delta is scheduled for March 1981. The SBS-A spacecraft will be the first capable of transmitting point-to-point voice, data, facsimile, and telex messages within the continental United States, as routine commercial service in the 12/14 GHZ K-J Band. Prior K-Band service on the ATS-6, CT S, and Telesat-D was experimental. This will also be the first use of the McDonnell-Douglas developed Payload Assist Module (PAM-D) which will place the SBS-A spacecraft into a synchronous transfer orbit. The spacecraft Apogee Kick Motor will be fired at transfer orbit apogee to circularize its orbit at geosynchronous altitude of roughly 19,300NM above the equator at approximately 106 degrees W longitude, roughly 3 days after launch.
