Development and Integration of the NPS Middle Ultraviolet Spectrograph with an Extreme Ultraviolet Spectrograph

Abstract

Current measurements of ionospheric electron densities are accurate but limited in scope. Present measurement techniques are land-based and the resulting data is not global in nature. Scientists at the Naval Postgraduate School (NPS) and the Naval Research Laboratory (NRL) are working on a joint research project to develop a technique to determine global ionospheric electron densities from satellite platforms. NPS developed a middle ultraviolet spectrograph with wavelength coverage of 1800 to 3400 A. This thesis developed the integration package that linked the spectrograph analog data to the Aydin Vector MMP-600 PCM Encoder. The integration package provided analog-to-digital conversion of the data, data storage for the digital data, and synchronization of the data collection and data transmission operations. Testing equipment was also developed to support laboratory calibration and in-place testing of the instrument. The test equipment provides computer generated synchronization signals and digital data acquisition. Theses.
