Projects / IridiumFlares


IridiumFlares is an application that can predict the flares made by the constellation of the communication satellites known as Iridium. A flare is a very bright phenomenon that occurs when the light of the sun or the moon is reflected by one of the satellites' antennas.

    Release Notes: A world map has been added to preview the selected observation site. The computation can now be optimized by ignoring the day-time passes. The elements filters automatically take into account the status of the element given by the site Celestrak. Corrections were made concerning the parallel computing on multi-processor systems. The sky view has been slightly enhanced.

      Release Notes: A sky view has been added, showing the sky as it can be observed when a flare occurs, including stars, constellations, the sun, and the moon. The flaring satellites can be tracked in real-time. For each flare, the sky view will display the time at which the intensity will be maximum (brightest flare) and the time during which the flare can be observed.

        Release Notes: The moon can now be used as a light source to compute moonlit flares. The antenna that causes the flare, the distance, and direction of the flare center have been added to the results. The computation of the estimated magnitude has been enhanced to take account of the range and illumination of the satellite. The elements can now be updated from a SpaceTrack account. A configurable list of ignored elements has been added, containing the satellites that produce no observable or predictable flares. The computations are parallelized on multi-processors platforms.

          Release Notes: A field "node" has been added to the computations. A tab "preferences" has been added to configure displayed fields and preferred units.

          •  09 Jan 2005 20:35

            Release Notes: This release adds percentage of illumination and eclipse type, if any (partial or total). Predicted flares from non-illuminated satellites are now hidden by default.
