On August 10, 2008, Compass-1 entered
Emergency mode. The cause was unknown and FH Aachen put out a call to all amateur radio operators to try to find out what was going on with the CubeSat. A hard reset occurred, only to bring the satellite into a circle of powering up, turning on the heaters, and

On 10 August 2008, the satellite developed a problem and switched into "emergency mode". Initial attempts to rectify this problem failed; however, normal operations were resumed on 10 September, with help from amateur radio operators around the world.

Most of the objectives for
Compass-1 were focused on the evaluation and testing of CubeSats and new technologies. It was made using scratch-built software, hardware, and parts, except the
