Abstract : The Electro-Dynamics Laboratories of Utah State University has modified the AFCRL trainable-instrumentation mount originally fabricated by Cook Electric Company so that it can be used as a tracking platform for two Type-III interferometers and one radiometer. The modification basically involved the addition of vibration isolation mounts and an enclosure with temperature control for the entire system which will be mounted in a KC-135 aircraft (3120). A dual-channel radiometer was designed and fabricated to fit in the remaining available mount space after the two interferometers had been installed. In connection with the readiometer design, an existing AFCRL radiometer originally built by GCA was evaluated to determine its usefulness in making airglow measurements. In addition to the 'Cook' mount modifications, a manually trainable mount was fabricated to incorporate one interferometer, one radiometer and a 16-mm camera. Also, an NIR radiometer was modified to be used for hand-operated tracking and the rapid-scan spectrometer was updated to increase its sensitivity and reduce its noise level. (Author)
