Abstract : During December 1980 the Position Location and Communication Effects Simulation (PLACES) Experiment was conducted to investigate the effects of structured ionospheric plasmas on satellite communication and navigation systems. A structured plasma environment was created by a 48-kg barium release from a rocket launched from Eglin AFB Florida. The experiment was directed by the Defense Nuclear Agency and involved ten government, industry and university organizations. Measurements of propagation effects on signals from the LES 8 satellite over the Pacific to a C-135 aircraft operating in the Florida area were conducted. Measurements of the fading depth and fade rate are included in the test results.
