Trouble for CubeSat Laser Communications Test
“After the CubeSat launched last Thursday, initial contacts and checkout of the satellite went well,” said Richard Welle, Director of the Microsatellite Systems Department at The Aerospace Corporation.
Last weekend, during extensive software upgrades, Welle told Inside Outer Space that the small satellite went through one of its normal reboot sequences in the middle of a software change in the attitude-control system (ACS) processor.
“When the satellite restarted, the ACS processor not only booted into a mode that disabled that processor altogether, it also limited the performance of several other processors. We have reproduced the anomaly in the ground unit, and understand the source of the anomaly,” Welle said.
