Description
3 microfiches (2 volumes) : negative, illustrations; 11 x 15 cm.
Summary
A management overview of the Attached Payload Operations Center (APOC) functional requirements and design are presented. The APOC was designed to support both Spacelab and non-Spacelab. For Spacelab payloads channel 2 and 3 data are input via a Statistical Multiplexer (SM) to the various SIPS functions. This system performs the inverse functions of the onboard Spacelab High Rate Multiplexer (HRM) enabling access to the data streams as multiplexed onboard the Spacelab. The contents and characteristics of channels one, two and three data as downlinked by the Tracking and Data Relay Satellite System (TDRSS) ku-band are given.
