Abstract:

The principal component of the Space Transportation System STS is the Earth-to-Orbit Shuttle EOS, which is a large piloted vehicle capable of transporting payloads into low earth orbit and return. A central feature of the EOS is the on-board checkout system, whose operational concepts include pre-flight checkout, in-flight status monitoring, and ground maintenance aids. The OBC is intended to be an integral part of the EOS avionics system. In order to minimize the weight and complexity of the cabling on board the EOS, an Integrated Data Bus IDB had been specified. Ideally, only the IDB should be used to interconnect all of the avionics hardware. However, where several components are co-located, there appears to be no objection to the use of subsidiary interconnecting cables minibusses provided that such cable runs are very short. Structurally, the IDB may take any convenient form but, unless some exotic method of data transfer is adopted such as lasers, the use of standard coaxial cabling is indicated. Author
