ZACube-2 (South African CubeSat-2), also ZA 004 , is a South African 3U CubeSat that was developed by the technical university CPUT and the F'SATI . The satellite is used for training and technology testing.
construction
The satellite carries an SDR platform as the primary payload, which is used to validate the ship identification system AIS . The satellite also carries an image sensor as a secondary payload for observing the sea surface and tracking forest fires. ZACube-2 is three-axis stabilized . The satellite has a UHF transceiver for control and telemetry, as well as an SHF transmitter for a downlink data rate of 2 Mbps. The SHF transmitter works on a circular patch antenna that is mounted on the side of the satellite facing the nadir . There is also a circular polarized VHF antenna for the SDR payload and a circular polarized antenna for the UHF transceiver.
mission
It was launched on December 27, 2018 with a Soyuz 2.1a / Fregat-M launcher from the Russia Cosmodrome , along with the main payload Kanopus-V5 Kanopus-V6 and 26 other satellites, including D-Star ONE Sparrow .
