The DIDM (Digital Ion Drift Meter) instrument was launched on the CHAMP spacecraft on July 15, 2000 at 13h 59 min 59.628 sec MET from the Plesetzk launch range in Russia. DIDM was successfully powered-on at 4:23 EDT (8:23 UTC) Monday morning (7/24/00). The High Voltage was turned on Wednesday (7/26/00) and all is well with the instrument.
Digital Ion Drift Meter (DIDM) instruments are designed to measure the velocity vectors of ambient ions at a spacecraft’s location.
