Since the defenceWeb article was written it is believed ZACUBE-1 and ZACUBE-2 have changed designation and the references to the 3U Cubesat ZACUBE-1 should instead read ZACUBE-2.
Students at the Cape Peninsula University of Technology (CPUT) have been building an amateur radio 3U CubeSat ZACUBE-1 that will carry out propagation research using a beacon on 14.099 MHz.
The objectives of the mission are:
1) Training of post-graduate students in Satellite Systems Engineering.
2) Earth observation using a visible band matrix imager payload and an S-Band payload data transmitter (2.4 to 2.45 GHz).
3) UHF Store & Forward system (70 cm amateur band).
4) Experimental 115200 bps L-Band to S-band data transponder.
ZACUBE-1 will conform to the 3U CubeSat standard with a maximum separated mass of 4 kg. The spacecraft will be 3-axis stabilized using a novel Attitude Determination and Control System (ADCS) developed by the University of Stellenbosch. The spacecraft’s Telemetry, Tracking, and Command (TT&C) system will operate in the 70 cm band and will be commanded from the amateur ground station at CPUT.
The website defenceWeb quotes a launch date of 2013.
The IARU Satellite Frequency Coordination Panel have agreed these frequencies:
Uplinks on 437.525 MHz and 1260.25 MHz and downlinks on 437.345 MHz and 2405.00 MHz.
Renier Siebrits ZS1MIR gave this presentation about the project on August 7, 2011.
CPUT students are currently involved in the development of a second amateur radio CubeSat, ZACUBE-2, which will be 10x10x10 cm with a mass of one kilogram.
