Summary
(Summary adapted from the GHRC web site)

The Satellite Coincidence Search Engine provides the WWW user with the
capability to determine when satellites were or will be over a
specified geographic area or within some distance of each other.

The Coincidence Search Engine may be used to search for times when up
to four satellites were over or within ... the same geographic area
simultaneously. Searches may be constrained by time, geographic area,
and/or distance between the satellites. The output consists of a
sequence of text lines listing the date, time, satellite name, and
latitude and longitude.

The program uses an archived database of element set data to calculate
the orbits, using a model supplied by the Colorado Center for
Astrodynamic Research (CCAR). Orbits may be extrapolated for future
times, but the accuracy of the orbit decreases as the temporal
distance from the last element set increases.
