Students of the Samara State Aerospace University are having trouble getting a signal from their satellite, SamSat-218D. They are now reaching out to the radio amateur community, inviting everybody with sufficiently sensitive
UHF VHF band (144 MHz) equipment to help by listening to SamSat-218D. The satellite was entirely built by students and went into space on board of a Soyuz-2 rocket on April 26, 2016. This is their call (translated by Google):
“To all radio amateurs who have the ability to receive signals from satellites in the
UHFVHF band (144 MHz).
April 28 during the first launch from the Baikonur East satellite SamSat-218D was launched, created by Samara State Aerospace University.
The satellite beacon, which transmits every 150 seconds (or 30 seconds), the word “SamSat-218D” for 15 seconds at a frequency of 145,870 MHz. The transfer is carried out in Morse code in the CW mode. During the passage of the satellite over our receiving station we hear fragmentary Morse code in background noise, but not sure of the extent of its authenticity.
We ask to listen to broadcast on the aforementioned frequency, record audio and send e firstname.lastname@example.org. For all matters relating to the reception, ready to provide additional information, if necessary. Handling large amounts of data will allow us to understand the nature of the problem (possibly satellite heavily spun at the exit of the transport and launch container) and try to estimate the rate of rotation “
SamSat-218D flies in a polar orbit, and according to the tracker on N2YO.com, it is currently over the Pacific, and should soon reach Europe. The rocket, a Soyuz-2.1a, which carried SamSat-218D and two other satellites, was also the very first launch from the new Vostochny Cosmodrome. So, while you wait until the satellite flies over your region, you may enjoy the launch video below.
This task is perfect for a network of satellite ground stations. We’ve reached out to the SatNOGS team, winners of the 2014 Hackaday Prize, to see about adding this satellite to the network’s listening schedule.
Thanks [Ivan] for the tip!
