UKS Spacecraft

The UKS spacecraft carried instrumentation to measure magnetic fields, positive ions, electrons, particle modulations, and plasma waves. It kept a station-keeping orbit with IRM to provide measurements of the interaction of the artificial ion clouds with the ambient medium, and in particular the formation and decay fo a magnetic cavity.

The UKS was power-limited, and operated for selected portions of each orbit from launch until January 16, 1985. Color microfiche of the UKS survey plots and hardcopy of summary catalogues are available in the NSSDC; for digital data sets Dr. D. Bryant or the instrument investigators should be contacted.
