Domanda brevissima! Ma quanti satelliti https://amzn.to/3AEQOc1 per uso radioamatoriale esistono?

[ExPirata]

Ciao iRadiato.
Non sono un appassionato di attività satellitare, pero cercando ho trovato questo sul sito dell'AMSAT, si tratta di una lista "non so quanto aggiornata" dei satelliti per uso radioamatoriale, prova a darci un'occhiata Ciao

SO-50 SAUDISAT-1C

Catalog number: 27607
Launch Date: December 20, 2002

Status: Operational.
Uplink:    145.850 MHz (67.0 Hz PL tone)
Downlink:    436.795 MHz

Reinhard, DJ1KM, reports:
SO-50 is in good health and it is easy to access the satellite. However, SO-50 needs to be opened by a control station before you can operate the Sat. There are (I believe) 3 control stations in UK and 2 in DL. I am one of these. If the satellite comes from a direction where no control station is it is most probably not switched on.

SO-50 carries several experiments, including a mode J FM amateur repeater experiment operating on 145.850 MHz uplink and 436.795 MHz downlink. The repeater is available to amateurs worldwide as power permits, using a 67.0 Hertz tone on the uplink, for on-demand activation.

UO-11 OSCAR-11

Catalog number: 14781
Launch Date: March 1, 1984

Status: Semi-operational.
Downlink:    145.826 MHz FM (1200-baud AFSK)
Mode-S Beacon:    2401.500 MHz

OSCAR-11 REPORT 22 May 2004

Once again I am indebted to Jeff KB2M and Ron VK5AKJ who provided telemetry during the period 20 April to 04 May, while I was on holiday. Many thanks for the files.

During the period 15 April to 22 May 2004 the 145.826 MHz beacon has been heard transmitting continuous ASCII telemetry from 23 to 29 April, and from 11 May to 21 May. During this period consistent signals have been received.

The beacon operates under control of the watchdog timer, approximately 10 days ON followed by 10 days OFF. Assuming that the 20 day cycle continues, the beacon should switch ON around 31 May.

The internal temperatures have decreased by 7.5C. They are now 4.6C, 1.6C and 8.0C for battery, telemetry electronics and command decoder, respectively. Solar eclipse predictions indicate that the temperatures will continue to decrease towards a trough in June/July and then increase until the end of September, when the satellite will encounter continuous sunlight for the remainder of the year. Higher temperatures and greater temperature changes are expected this year, compared to 2003.The battery voltage observed during daylight passes has decreased by 0.4volts. Observations have varied between 12.5 and 13.4 volts, with an average value of 13.0 volts.

Spin periods of approximately 690 to 2500 seconds have been measured from the magnetometer telemetry. The rotational speed has decreased since the last the reporting period, and at the current very low rates, is difficult to determine with any accuracy. The direction of rotation has reversed.

Users of OSCAR-11 should note that the date in the telemetry is now advanced by FOUR days. The time is advanced by 19.8 minutes, and this error is increasing by about one minute per year.

OSCAR-11 now operates in a default mode, controlled by the watch-dog timer. The satellite transmits continuous ASCII telemetry for about 10 days on 145.826 MHz, followed by about 10 days of silence. This regular sequence might be interrupted by ground control, at any time.

The mode-S beacon is ON continuously, even when the VHF beacon is OFF, nominally transmitting an unmodulated carrier on 2401.5 MHz. There is however a VERY low level of AFSK modulation, (now a constant audio tone), which has been detected on strong signals. Telemetry indicates that the beacon has partially failed, and is delivering half power. This beacon is a useful test source for those testing mode-S converters. However the signals are very weak, and there is a lot of Doppler. Users should also note that the polarisation of OSCAR-11 is LHC. Any reports of reception on 2401.5 MHz would be most welcome. Please e-mail g3cwv@amsat.org.

The 435.025 MHz beacon is normally OFF. It can only be heard on the very rare occassions when the satellite is being commanded by ground control, i.e., within range of Guildford, UK. When the 435 MHz beacon is transmitting, the 145 MHz beacon is normally OFF. The data transmitted is mainly binary.

Listeners to OSCAR-11 may be interested in visiting my web site.

The web site contains details about using a soundcard for data capture, and also details about using hardware demodulators. There is software for capturing data, and decoding ASCII telemetry. There is an archive of raw data for analysis, which is continually being expanded, as new data is captured. Originally this was for WOD, but it is now being expanded to include ASCII telemetry. At the present time the telemetry covers 1996 to April 2003. I will add other years as time permits. In parallel there is a news archive which provides an overview of the state of the satellite, at the times when the telemetry was captured.

If anyone out there can provide any data, particularly for the 1984 to 1993 years, this would be most appreciated. Please e-mail me with details. However please DO NOT SEND ANY FILES, before further discussion.

Also included are some audio files, examples of each type of data transmitted by OSCAR-11, each one plays for about ten seconds. There are also examples of mode-S reception. All the audio files are zipped, so that they can be played off-line. These should help listeners identify the various types of data, and give an indication of the signal quality required for successful decoding.

Everyone is welcome to use the digipeating/APRS features of Sapphire, callsign KE6QMD, as per the user service agreement located at http://web.usna.navy.mil/~bruninga/pcsat/contract.txt.

There will be occasional dropouts caused by the CW beacon, and users are advised to expect extra packet chatter during West Coast (USA) passes, as some schools are using Sapphire for operations training.

Student built Sapphire was launched through the U.S. Naval Academy Satellite program. Its primary missions are sensor experiments, a camera, and voice synthesizer. For more information, visit the Sapphire web site at http://students.cec.wustl.edu/~sapphire/sapphire_overview.html

Freeman, N5FPP, reports:
Tonight's passes of RS-15 started out with a strong beacon transmitting telemetry at 0400, by the 0605 pass over North America the beacon had degraded to a continuous carrier lasting upwards to 30 seconds. The frequency shifted up and down quite a bit as you listen to it. On the 0605 pass once RS-15 went into eclipse the beacon died altogether. It's hard listening this bird die.

ANS is looking for more confirmations of RS-15 coming back.

AO-49 AATiS OSCAR-49 (SAFIR-M)

Catalog number: 27605

Status: Semi-operational
Uplink:    435.275 1200-baud AFSK
Downlink:    145.825 9600-baud FSK
(optional voice message)
Broadcast callsign:    DP0AIS

AO-49 (SAFIR-M) is a German amateur radio payload onboard the small German scientific satellite "RUBIN-2".

AO-49 was built by the German amateur radio association "AATiS e.V." (German acronym for "Arbeitskreis Amateurfunk und Telekommunikation in der Schule", which means: 'working group for amateur radio and telecommunications in schools'). AO-49 is designed as a "store and broadcast" system for APRS based messages, dedicated for the use of schools in combination with the existing WX-Net and planned buoy experiments in Germany.

No transmissions detected since the 1st of February 2003! It appears AO-49 is not properly aligned to illuminate the solar panels. This should end soon. Due to its orbit, AO-49 will be in a phase without eclipses until 13Feb03.

Martin DG8UAU has written a small software program "SAFIR-M Decoder" to allow decoding of the received DATA0 frames. It is available at http://amend.gmxhome.de in the section Aktuelles.

Details on AO-49 (SAFIR-M) can be found at http://amend.gmxhome.de.
