Orbiting Data Relay Network communications system provides continuous wideband communication between ground and earth orbiting spacecraft via synchronous satellite repeaters
Visible and IR spectral reflectivity of Apollo lunar landing sites, attributing reflectivity differences to compositional and/or mineralogical differences
Circulation and temperature fields indices used for studying tropospheric-stratospheric interactions during stratospheric warming at constant pressure levels
Electro-optical system can scan a large /100 ft./ antenna in 30 seconds. Comparison of the reflected signal with a reference signal from a Pockel-cell modulator driver yields a signal that can be correlated with the distance covered by the laser. A scanning arrangement then enables contour measurement.
