Mapping 38.2 MHz cosmic noise/particle precipitation in .7 x 7 beams 12.8 deg, ~200 x 200km at 90km altitude. A Southern Hemisphere Imaging Riometer Experiment. A joint project of the Australian Antactic Division, University of Maryland and the University of Newcastle.
A riometer is essentially a wide-angle radio telescope that is used for studying the aurora.
This work is included in the ongoing ASAC project 877 (ASAC_877).
These data are held on the Space and Atmospheric Sciences servers at the Australian Antarctic Division, and also on DVD at the Australian Antarctic Data Centre.

The visual satellite ground tracks and coincidence data within COVE are determined using an SGP4 propagator with TLE data as the input. TLE data is gathered every hour from celestrak.com or n2yo.com if it is available. Pop-up windows over ground tracks or data from coincidence calculations will indicate "(from TLE)" when the SGP4 propagator is used. Otherwise the ground track and coincidence data represent the ideal orbit behavior with J2 perturbations only. Higher order gravity terms, drag, 3rd body perturbations, and satellite maneuvers are not included in the J2 propagation. This tool is not intended for use in performing mission critical analyses which require precise orbit information.
