AO-27’s on/off times run open-loop and have drifted a bit so that the information on ao27.net is out of date. We’re trying to collect current telemetry before attempting to upload new settings.
AO-27 sends 20 seconds of AFSK telemetry followed by 240 seconds of FM repeater operation during descending nodes (North to South passes). As best we can determine from Satnogs observations, the satellite currently turns on when near the equator and shuts off at about 12-14 deg South latitude. Stations with UHF receive capability should be able to receive the telemetry and detect/use the FM repeater operation.
We think the ascending node on time begins when AO-27 is at about 75 deg N latitude and ends around 85 deg N as the satellite begins the descending part of the orbit. Stations probably have to be fairly far north with good northern horizons to hear anything. No telemetry is sent on ascending node passes.
The AO-27 command team would greatly appreciate reception reports, especially with the time(s) telemetry or repeater operation started/ended. Please provide station location, 6 character grid square is sufficient.
If you have AFSK reception/decode capability, any telemetry successfully decoded.
Reports from northern stations able to copy the start or end of the ascending node on time are also sought.
Please send reports to firstname.lastname@example.org
Thanks in advance from the AO-27 command team.

Jean Marc Momple, 3B8DU reports: “It seems to be confirmed that MIR-SAT 1 re-entered.
The last valid telemetry signals of MIR-SAT 1 (worldwide) was received in Mauritius with the UoM ground station by YOG-3B8 (Dr Yogesh Beeharry,
Lecturer of the Department of Electrical and Electronic Engineering, Faculty of Engineering of the University of Mauritius). Yogesh, member of this forum
led a team of UoM students who build their own ground station. This was at 01:36 Hrs local time this morning and JA0CAW (Tetsu, an experience Satellite
HAM) confirmed to me by mail that no signals was received from MIR-SAT 1 at 05:03 (MRU time). More many other regular reporting HAMs confirmed to me
that no signals received from our bird today.
This confirms that MIR-SAT 1 re-entered between 01:36 and 05:03 Hrs and probably burned up around 110Km in a blast of flame, unfortunately the
location is not known as mainly over oceans during the time window.
I also confirm that a few minutes before last observation from Yogesh that I received the TLM of MIR-SAT 1 and also made successful Digipeats through it
(see attached screenshot), the bird was at about 160km altitude at that time, this was my farewell to MO-112.
Congratulations to Yogesh to be the last recorded person on this planet to have successfully decoded our 3B8 bird.
RIP MIR-SAT 1, you have been a great tool for educational and HAM experiments.
One page turned and the next (better) opens, MIR-SAT 2 ??? why not?, just a question of vision, willingness, motivation and hard work.
73, Jean Marc, 3B8DU”

Thank you for the report that you sent to ARISS. In the attachment, I am sending you the official “ARISS SSTV Award”.
April 12th is the annual Cosmonautic Day to commemorate the first human flight in the Space by Jurij Gagarin in 1961. The images of this ARISS SSTV event series 20 are also honouring the “Women in Space”. Our ARISS award shows from the left to right: Linda Godwin – the first female astronaut to conduct ARISS school communications from the ISS; Peggy Whitson – the first female ISS commander; Valentina Tereshkova – the first woman in space.
The ARISS SSTV event was realized thanks to the commitment of Sergey Samburov RV3DR from ARISS Russia and Frank Bauer KA3HDO – ARISS International Chair, as well as many other people. The official ARISS awards are provided by the ARISS Ad-hoc Award Committee: Oliver DG6BCE (chair), Armand SP3QFE, Francesco IK0WGF, Bruce W6WW, Shizuo JE1MUI, Darin VE3OIJ, Ian VE9IM.
Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the International Space Station (ISS). The primary goal of ARISS is to promote exploration of science, technology, engineering, the arts, and mathematics topics. ARISS does this by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students. Before and during these radio contacts, students, educators, parents, and communities take part in hands-on learning activities tied to space, space technologies, and amateur radio.
Greetings – Slawek SQ3OOK, ARISS SSTV Award Manager
Toktar Ongarbayuly Aubakirov (born on 27 July 1946) is a retired Kazakh Air Force officer and a former cosmonaut. He is the first person from Kazakhstan to go to space. On 2 October 1991 he launched with Russian cosmonaut Alexander Volkov as flight commander, and the Austrian research cosmonaut Franz Viehböck in Soyuz TM-13 from the Baikonur Cosmodrome spaceport, and spent over eight days in space. Their mission was the last launched by the Soviet Union, which dissolved shortly thereafter, with Aubakirov becoming a citizen of the independent Republic of Kazakhstan. Since 1993, he has been the general director of the National Aerospace Agency of Republic of Kazakhstan. He was a member of the Kazakhstan parliament. Now he is a pensioner and consultant.

I think digital reception only makes sense if the data of several receivers can be stored together in a database and thus missing segments are filled automatically. The individual reception in this format seems rather unfavourable.
