The team members at SunSpace are still incrementally reading back the program code from the nine power modules in an effort to determine the extent of the corruption. With SumbandilaSat going through eclipses, the satellite is not as available as the team would like. SumbandilaSat’s batteries failed, which means that the satellite is only active when the solar panels are illuminated.

“We need the information to confirm that the changes we made to stop repeated corruption were effective,” said Johann Lochner ZR6CBC, who spends a considerable amount of his free time on recovery of SumbandilaSat. “It is our aim to ultimately reprogram one of the power modules to automatically switch the amateur radio transponder on and off.”

Because of the shorter illumination of the solar panels in the Southern Hemisphere, and most likely poor orientation of the satellite with respect to the sun, progress is much slower than originally anticipated. “Where we had three passes to work with in January, we currently have one,” said Lochner.
