Description
Summary:Contract effort can be grouped under airborne and ground support instrumentation systems, rocket and balloon field programs, and evaluational testing of commercial telemetry and satellite system components. Instrumentation developed has included programmable timers, in-flight calibrators, first motion switches, beacon delay modules, ground radiometer support instrumentation and a six decade frequency meter/logic probe. Rocket field programs have been involved with ICE CAP -73B, -74A, -74B, -75A, -76, PRECEDE, EXCEDE II, radio scintillations, twilight D-region studies and a VLF experiment. In most of these instances airborne telemetry as well as ground based testing and support was provided. Balloon borne instrumentation has been concerned with airborne photometer measurements and an extreme ultraviolet experiment. Work has included instrumentation, telemetry and field support. A specialized PCM test system and simulator was developed to supplement the testing program. Brief motion is given to the components tested under the evaluation and EMI programs since detailed results are published in reports which are available to authorized agencies.
