Abstract:

The Position, Location, and Communications Effects Simulation PLACES experiment was conducted at Eglin AFB, Florida, during the period of 4 to 12 December 1980. Four barium releases were made on four separate days. The primary experiment was to measure time-of-arrival fluctuation and spread in a signal passed through the barium clous from a rocket-borne beacon to a ground receiving station. A secondary experiment was the measurement of phase and amplitude scintillation on a UHF signal from the LES-8 satellite, passing through the barium cloud to a receiver in a C-135 Aircraft. In addition to these two experiments, a rocket-borne electron density probe and mass spectrometer made in-situ measurements on the barium cloud. The ion cloud position was determined in real time by the FPS-85 radar operating in an incoherent scatter mode. Ground optics, an ionosonde, a magnetometer, and a low-light-level TV tracking system also supported the experiment.
