GAS Verification Payload - From concept through flight

The GAS Verification Payload (GVP), successfully flown on STS-3, was the forerunner of the Get Away Special class of payloads. Intended to provide GAS experiments with flight environmental information, it also served to shape out the GAS support systems and establish areas of programmatic understanding between the GSFC, JSC, and KSC. Originally envisaged as using a sounding rocket build-it, test-it, fly-it approach with minimum paperwork, this naivete dissipated when faced with the manned space flight world of JSC. What evolved was an understanding by both disciplines that safety and reliability could be achieved at lower cost without compromise.

An autonomous payload controller for the Space Shuttle

The Autonomous Payload Control (APC) system discussed in the present paper was designed on the basis of such criteria as minimal cost of implementation, minimal space required in the flight-deck area, simple operation with verification of the results, minimal additional weight, minimal impact on Orbiter design, and minimal impact on Orbiter payload integration. In its present configuration, the APC provides a means for the Orbiter crew to control as many as 31 autononous payloads. The avionics and human engineering aspects of the system are discussed.

Logic-state-change indicator and frequency doubler

Low-power TTL circuit produces an output pulse whenever logic level at its input terminal changes. Circuit can also be used for doubling square-wave frequency.
