Definition of Throw-Away Detectors (TADs) and VLF antenna for the AMPS laboratory

A Throw Away Detector (TAD)/subsatellite to be used as an experiment platform for the test flights to map the EMI from the shuttle and during the AMPS science flights is defined. A range of instrument platforms of varying capabilities is examined with emphasis on the EMI test vehicle. The operational support requirements of TAD/subsatellites are determined. The throw away detector is envisioned as a simple instrument package for supporting specific experiments

Space - Satellite Communication in the 70\u27s

Space-satellite communications of the 60s will not suffice for the 70s. A refinement must occur. International emphasis for operational satellite systems demands more sophisticated systems and equipments to handle the large number of new applications arising. Payloads must include gear for weather observations, communications, navigation, reconnaissance, early warning, public health safe-guarding, and nuclear test monitoring. What direction should the communications industry take to accomplish these things ? What technological support is needed? Now is the time to take an overall view of the entire space-satellite field. Engineering during the 60s devoted attention to brute force communication technology necessary to prove feasibility and reliability. This paper examines the initial evaluation criteria and experimental results for the three categories of systems comprising this field: Satellite Communications, Spacevehicle Contained Communications, and Ground-based Tracking and Telemetry Communications. The feasibility requirements established early in the 60s form the framework from which today\u27s technique and equipment trends have developed. See Figure 1. Studying these trends provides the clue to the special problems encountered in each of the above categories
