I juli är det dags för ARISSat-1 och då anordnas en mottagningstävling. Se nedan:
ARISSat-1 is scheduled for deployment from the ISS in July. It has a
composite VHF downlink that will easily fit into the FUNcube Dongle
receive spectrum. The telemetry is 1000 bps BPSK and can, of course,
also be received with a normal SSB 2 metre receiver.
The expected signal levels from ARISSat should be similar to those we
expect from FUNcube itself (and also eventually from UKube) and the
team are keen to discover what will be the minimum and best type of
antennas for schools to use with a FCD. Therefore user experience with
the ARISSat signals will be very valuable in making this determination.
To encourage everyone to receive ARISSat signals we are offering a FUN
reward for listeners!
There are a number of categories for this challenge including:
1. The first FCD user, from each continent, who can post a spectrum
recording of the received signal together with evidence of decoding
the data using the ARISSat software and of sending it to the ARISSat
data warehouse.
2. The first non-FCD user, from each continent, who can provide evidence
of having decoded the signals and of sending it to the ARISSat data
warehouse.
3. The listener, using a FCD or not, who can demonstrate satisfactory
reception of the telemetry in the same ways as described above,
using the “smallest” possible receive antenna. The actual closing date for
this part of the challenge will be announced later.
4. All other entrants who can demonstrate that they have been having
FUN!
Please submit your “entries”, including your location, station details
(including FCD serial number where applicable), postal address and
reportsto g0auk<at>amsat.org.
