The first 3.4 GHz CubeSat
UNSA-SAT1 hopes to be the first CubeSat to make use of the 3400 MHz
ITU Amateur-Satellite Service allocation
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 ground station 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.
