Development of the Spartan 101 navigation and pointing timeline
This paper presents the techniques and analyses that were used to construct the Spartan 101 mission pointing timeline for the Space Shuttle Orbiter-detached portion of its flight. This covers the design process that had to transform requirements and constraints originating from the experimenter, the Space Transportation System, and the payload hardware design into a workable set of pointing instructions sequenced to mission events. The paper will discuss the technical approach used for initial attitude acquisition, determining target visibility, observation scheduling, and calculation of vehicle maneuvers.

The Space Transportation System/Spartan interfaces - An approach for low cost spacecraft
Using the Spartan 101 payload as an example this paper outlines the process of flying a low-cost spacecraft as a customer aboard the Space Shuttle, concentrating on the physical and organizational interfaces to the Johnson Space Center (JSC) and the Kennedy Space Center (KSC). These interfaces fall into four classes, namely, JSC safety, KSC safety, JSC operations and KSC operations.

Development of a magnetic acquisition and attitude control system for spinning rocket payloads
An attitude control system capable of pointing the roll principle axis of a spinning payload to within one degree of the magnetic field vector was flown successfully in 1981-82 aboard three Black Brant X payloads and one Terrier Malemute payload, and additional flights with the system have been requested. Using a filtered linear combination of signals provided by a single-axis rate gyro and a two-axis magnetometer, and control actuation from two cold-gas thrusters, the system can be assembled from standard rocket components and fitted to any payload size.

Development of an experiment of opportunity test payload for the space transportation system
This paper describes a means for flying existing Sounding Rocket payloads aboard the Space Shuttle by developing small experiment carriers which become detached from the Orbiter and are later retrieved and reused. An effort is underway at the Goddard Space Flight Center to develop such a carrier which would be flown as an Experiment of Opportunity Payload (EOP). The activity is viewed as a feasibility test, and success will encourage the construction of similar packages for additional sounding rocket experiments, for eventual evolution of p

Free-flying Shuttle payloads - An extrapolation of sounding rocketry into the Shuttle era
A concept is described for flying scientific and other instruments on the Shuttle, using a free-flying payload. Low costs are maintained by minimizing interfaces with the Space Transportation System and by assembling the payload using modified sounding rocket hardware. This approach allows all Shuttle missions to be considered for scientific missions and gives the Spacelab program the freedom to concentrate on those missions which can take special advantage of supervision by the Orbiter crew.
