Target satellite perigee:   286.00 km
Target satellite apogee:    296.58 km
Velocity at perigee:     7.7369 km/sec
TLE collision search file: junk.txt

COLA will search for satellites having altitude ranges
that intersect the range from   276.00 to   306.58 km,
and that come within  10.0 km of the target satellite at
a time within +/-  10.0 days of both satellite epochs.


Satellites in range of CRISTA-SPAS  297 x 286 km:    2
