ARLA/CLUSTER: Já se escutam os sinais do CubeSat brasileiro AESP-14 em 437,600 MHz

AESP-14 CubeSat deployed from ISS

On Thursday, February 5 the Brazilian satellite AESP-14 was deployed
from the International Space Station (ISS) but so far no signals have
been heard

The AESP-14 is a 1U CubeSat developed by undergraduate and graduate
engineering students at the Technology Institute of Aeronautics (ITA)
in Brazil. The satellite’s primary mission is to test the various
subsystems in the space environment.

The satellite was sent to the ISS as cargo on the SpaceX Falcon 9
mission CRS-5. Launch had been scheduled for December 16, 2014 but was
postponed three times and it wasn't until January 10, 2015 that the
launch eventually took place. Since arriving at the ISS on January 12
AESP-14 has been awaiting deployment by the JEM Orbital Deployer
(J-SSOD) which is in the Japanese Kibo module..

The deployment took place around 1250 UT on Thursday, February 5.
The AESP-14 telemetry beacon has a power output of 500 mW and uses
AX.25 on 437.600 MHz with 9600 bps GMSK modulation (G3RUH standard).
It should have started transmitting 30 minutes after deployment but as
of Thursday night nothing had been heard. It may be the battery did
not survive several months without being recharged or the antenna may
have failed to deploy.

The AESP-14 team would like to ask the help of radio amateurs around
the world to forward any received telemetry frames back to the team.
For this, please save the AX.25 frames in KISS format and forward the
file to aesp14  ita.br

The satellite has an amateur radio experiment developed by the
Americana Amateur Radio Club (CRAM). The experiment consists of the
random transmission of 100 sequences of ASCII characters prefixed with
the “CRAM” word that will used as part of a contest among receiving
stations. The first 10 amateur radio stations that complete receiving
the 100 sequences will be awarded a commemorative diploma.
