Spacecraft

The satellite makes use of the CubeSat form factor and contains a mix of in-house developed and commercial-of-the-self components. Components where sourced from Clyde Space and Innovative Solutions In Space. ZACUBE-1 is South Africa’s first launched CubeSat and third Satellite (ZA-003).

The UHF/VHF transceiver used on ZACUBE-1 was developed and built in-house at F’SATI/CPUT and is still functioning nominally after more than two years on orbit. This transceiver served as the base design for the CMC UHF/VHF transceiver which is now commercially available.

Payload

  • High-Frequency (HF) beacon transmitter
  • Low resolution CMOS imager

Details

  • Satellite name: ZACUBE-1 (TshepisoSat)
  • Satellite Catalog ID: 39417
  • International Designator: 2013-066B
  • Transceiver modulation and data rates: UHF AX.25 1200 bps AFSK and 9600 bps GMSK. HF payload in CW.
  • Satellite antenna polarization: Linear
  • Satellite transceiver manufacturer: CPUT/F’SATI

Launch

ZACUBE-1 was successfully launched on 21 November 2013 at 07:10:10.147 UTC from Yasny, Russia aboard a DNEPR launch vehicle as part of the ISILAUNCH03 Mission.

Launch was 2 years, 8 months, 8 days, 22 hours, 7 minutes ago ago.
