High school students in Brazil building QO-100 ground station

High school students in Brazil are building a ground station for the
amateur radio transponder on the QO-100 geostationary satellite as part of
a STEM education project

A group of eight students, from Colégio Embraer Casimiro Montenegro Filho
in Botucatu state of São Paulo, are participating in all steps of the
project with the help of teachers and amateur radio volunteers from
LABRE/AMSAT-BR (Edson PY2SDR, Demilson PY2UEP, José PU2MJR).

The station consists of a 1.2m offset dish antenna, an Amiko L-104 LNBF, a
home-made bias-t, a RTL-SDR receiver and SDRsharp software running on a
dedicated computer. During the project students were exposed to several
STEM topics related to radio communications, antennas, software defined
radios, geostationary orbits as well as hand-on activities during the
station assembly and configuration.

The students were able to successfully receive test transmissions in morse
code kindly made by Roland PY4ZBZ and Fábio PY4AJ. The next step of the
project is to introduce digital communication concepts, decode the BPSK
engineering beacon and finally to add transmission capability to the
station. In the near future, besides making contacts with other stations on
QO-100, the students would also very much like to contact other schools and
students in the QO-100 footprint.
