Integrated Data Bus Study,
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)
