ARLA/CLUSTER: AfriCUBE: Um Cubesat com transponder SDR

[João Costa > CT1FBF]

An SDR Cubesat on the cards

*AMSAT SA* has announced that parallel to its analogue Kletskous CubeSat,
the group is working on a digital project featuring a Software defined
transponder.

Called *AfriCUBE*, the CubeSat will use the same space frame as KLETSKOUS.
Anton Janovsky is current building a prototype transponder.

AMSATSA is inviting persons interested in becoming part of the development
team to send their details to admin  amsatsa.org.za.

Meanwhile the development and final construction of the AMSAT SA KLETSKOUS
is plagued by electronic component obsolescence. This forces unwanted
design changes to be made to ensure that when the time comes to construct
the final launch unit, the main components are still available. The
KLETSKOUS team decided to freeze the design of KLETSKOUS and purchase a
quantity of devices to proactively mitigate future obsolescence. This
decision will also speed up the process of putting a final satellite on the
table.

"Every time we change designs to mitigate for the discontinued components,
it is like starting the design afresh, often creating new problems that
have to be solved", Hannes Coetzee, ZS6BZP said.
"By freezing the design, in other words making a final decision on the main
specialised devices to be used, we will be able to speed up the process of
putting a flight ready unit on the table."

KLETSKOUS is not a textbook design. Most of the sub-components that will
make up KLETS KOUS are designed and being built by the volunteer team. "We
do not have the finances to go out and purchase sub-units and simply wire
them up," Hannes said.

AMSAT SA is holding its 2019 Space Symposium on Saturday 16 March 2019 in
Gauteng. The theme of the conference is "Space Science with Amateur Radio."
Paper proposals are invited. Send your synopsis to admin  amsatsa.org.za.
