KLETSKOUS PLAQUED BY BATTERY FAILURE
Kletskous on BACAR 6 worked perfectly on the ground while being assembled in the train of BACARSats to prepare for launch on a high-altitude balloon and for a short period while ascending on the balloon. Then suddenly the transponder switched off. After recovery it was found that the battery had failed, the one cell was dead.
Kletskous recovered after the BACAR6 flight.
“We are obviously disappointed but also pleased that the space frame stood up to the rapid descend and the hard landing. “This was the first time we flew a nearly complete Kletskous. Only the solar panels and the on-board controller were left on the ground”, Hannes Coetzee ZS6BZP, the Kletskous Project Manager said. “It is a concern that the battery failed, and that is a matter to be investigated.”
“As part of the next phase in the development, the designer of the transponder, Leon Lessing, ZS6LMG, is subjecting the transponder to some vigorous ground testing. When that is successfully completed Kletskous will be placed on a high site for operational testing
The Kletskous team meets on 20 August for a gull analysis on the flight
African Radio Amateurs will soon have access to a geostationary satellite
In the next few years radio amateurs will have access to two geostationary platforms, one that will service the Americas and another one, particular attractive to South Africans, that will be positioned at 26° East giving 24 hour access to Africa, Europe and the Middle East. These two geostationary projects will be included in commercial platforms similar to Amateur Radio Satellite (AMSAT) South Africa seeking to have an amateur radio transponder included in South Africa’s next satellite currently designated as EOS-1 (Earth Observation Satellite).

More Kletskous Progress
A flight-ready solar panel for Kletskous.
The solar cells are glued to the PC board using conductive silver epoxy. This is done under vacuum to prevent bubbles being formed in the epoxy. Bubbles may burst in the vacuum of space, fracturing the paper thin glass solar cell and destroying it in the process.
