COMPASS-1 (also known as Compass One) was a German amateur CubeSat picosatellite, built and operated in the late 2000s by Aachen University of Applied Science. It was launched by the Indian Space Research Organisation, aboard a PSLV rocket, on 28 April 2008.[1] Its primary mission is remote sensing; however, it also contains some technology demonstration experiments regarding the use of small satellites.[2]

On 10 August 2008, the satellite developed a problem and switched into "emergency mode".[3] Initial attempts to rectify this problem failed; however, normal operations were resumed on 10 September, with help from amateur radio operators around the world.[4][needs update]
