Built by students at the Instituto Astronómico y Aeroespacial Pedro Paulet in Peru, UNSA-SAT1 is a 2U spacecraft (20x10x10cm) which will be part of the QB50 constellation of 50 CubeSats.
The aims of this CubeSat include: upper atmosphere science; radio communication experiments; technology demonstrator; education, training and outreach.
The team are proposing a 435 MHz transceiver using BPSK and additional transmitters on 2.4 GHz,and 5.8 GHz. They also also hope to have a 230 kbps BPSK downlink on 3.4 GHz – this will only operate in Region 2 when the spacecraft is overhead the groundstation in Peru.
The ITU Amateur-Satellite allocation at 3400-3410 MHz is available in ITU Regions 2 and 3 but not currently in Region 1 (Europe/Africa) although it is believed Denmark and Norway have allocated the band to the Amateur-Satellite Service.
