Description
KITSAT-OSCAR 25 is a South Korean experimental microsatellite based on
the SSTL UoSAT bus built by the Korean Advanced Institute of Science and
Technology (KAIST). KO-25 is operated from The
Satellite Technology Research Center (SaTReC) in South Korea.
KITSAT-2 was one of three amateur satellites that was launched together
on a Arianne V59 rocket from French Guiana at approximately 0147 UTC, 26
September 1993. It was later designated KITSAT-OSCAR-25 once in orbit.
The other two amateur spacecraft were Italy-OSCAR-26 (IO-26)
and AMRAD-OSCAR-27 (AO-27) (aka Eyesat-A).
KO-25's mission is to take CCD pictures, process numerical information,
measure radiation, and receive and forward messages. The Infrared Sensor
Experiment (IREX) is designed to acquire I/V characteristics of IR sensors.
A passive cooling structure was devised for this experiment and currently
the ground controllers are monitoring the temperature of this experiment.
KO-25 is presently operating as a packet store-and-forward satellite,
very similar to UO-22 and KO-23.
Ground
station requirements are the same for all three spacecraft.
