International Telemetering Conference Proceedings / October 25-28, 1993 / Riviera Hotel and Convention Center, Las Vegas, Nevada / This paper will describe the effort to provide a common telemetry system for the
Control Center Complex (CCC) which will process data from both the space shuttle
and the space station vehicles. It is being developed for the manned spaceflight
program at Johnson Space Center.
Space shuttle uses a traditional Inter-Range Instrumentation Group (IRIG) telemetry
format and Space Station Freedom utilizes the more recently developed Consultative
Committee for Space Data Systems (CCSDS) standards for packet-based telemetry
Although the two telemetry streams are very different in structure, a front end system
is being developed which will isolate the differences and provide a common data
format to the downstream elements of the control center. Because of this, a CCC
workstation could receive and process data from either space station or space shuttle
or both using a identical set of workstation program tools. The generic telemetry front
end processor, which is called the Consolidated Communications Facility (CCF), will
not only provide a cost effective method of processing space shuttle and space station
data, but also will position the CCC to support anticipated requirements of' future
programs.
The development goals for the CCC are to reduce development and sustaining costs.
In the CCF project, commercial-off-the-shelf (COTS) equipment is stressed to allow
modular maintenance. In addition, the project has emphasized the development of a
automated features in the telemetry stream selection and processing which reduce the
amount of operator attention needed. The system has been designed to include
robotics in the recording operation and artificial intelligence for detecting faults.
This paper will review the concept development for processing telemetry and outline
the architecture of the front end CCF project. It will discuss the goals and major
influences on the design, and provide a status on the development. Ability of the
current COTS marketplace to meet the goals will be discussed. In summation, this
paper will describe generic telemetry processing in the context of the CCC being built
at Johnson Space Center.
