Abstract : The contract effort can be grouped under programs concerned with orbiting vehicles, evaluation of commercial telemetry system components, and field support for certain sounding rockets and balloons. The orbital vehicle effort is concerned with telemetry systems, a tracking system, a data storage system, aspect instrumentation and determination, a solar power system and a radiometer control and calibration system. A tabulation is given of commercial airborne telemetry components tested and evaluated since detailed results are published in scientific reports which are available to authorized agencies. The results of a UHF telemetry system test flight are discussed. The field support rendered in connection with the various programs is tabulated. Specific subroutine programs connected with aspect determination are included in appendices. (Author)
