iss....prossimi ascolti

[ale_nest]

Mannaggia non lo sapevo Silvio.
Ora resto con le orecchie dritte per le prossime orbite.

Comunque chi riceve i bollettini del progetto ARISS lo sa già, per il resto del mondo invece lo scrivo qui: con il vettore HTV-4 giapponese è stata appena portata a bordo tutta l'attrezzatura per trasmettere anche video, in banda S all'interno del progetto Ham Video.

Ecco il bollettino.

Ham Video transmitter onboard Columbus

How a DATV transmitter on S-band is being added to the ARISS equipment onboard the International Space Station has been related in an announcement recently circulated and available at www.ariss-eu.org/HamVideo.pdf

The ARISS Ham Video transmitter is presently onboard Columbus. The transmitter was delivered by Japanese cargo spacecraft HTV-4, which launched August 4 and docked 5 days later.

ESA astronaut Luca Parmitano IR0ISS reported that the bags are stored in Columbus. There are two bags: one for the transmitter, the other for the power, camera and antenna cables.

Installation will be done by US astronaut Michael Hopkins KF5LJG who has been trained for the commissioning of the Ham Video equipment.The commissioning is planned later in the year, possibly end October when there are favourable passes over Italy. Indeed, the tests transmissions for the commissioning of the onboard equipment will be received by the ground station of the "Centro di Geodesia Spaziale" of the Italian Space Agency, located in Matera, Southern Italy.

We will report in due time on the commissioning procedure which will involve a series of tests to be performed during 3 or 4 ISS passes.
Possibly, the Ham Video transmitter will transmit continuously between the commissioning steps offering amateur ground stations the opportunity to test and tune their receiving equipment. The transmissions will be performed in automatic mode, without requiring crew time. The camera, which runs on a battery, will not be used and the ground stations will receive a black image.

Meanwhile, commissioning is being prepared steadily. The kick-off meeting took place November 2012 at ESTEC, the European Space Research and Technology Centre, located in Noordwijk the Netherlands. Detailed procedures are examined and finalized during weekly ESA/ARISS teleconferences. A preliminary EST (Experiment Sequence Test) is planned 28-29 August. The test will involve the ARISS ground station IK1SLD, located in Casale Monferrato in Northern Italy.

IK1SLD, which is an ARISS telebridge station often used for educational ARISS school contacts on VHF, has been upgraded for S-band reception. Ham Video manufacturer Kayser Italia has delivered a 1.2 meter dish, a down converter and precision tracking motors, which are part of the ESA funded equipment. For the EST, the station will receive a DATV signal from a local low power S-band test transmitter. The decoded signal will be webstreamed to the BATC server. The British Amateur Television Club offers ARISS free access to their server. ESA examiners will connect to the BATC server and evaluate the reception. Test transmissions at IK1SLD will cover the different frequencies and symbol rates available on the Ham Video transmitter.

Web streaming will take advantage of the special software developed by Jean Pierre Courjaud, F6DZP. References are available in the HamVideo.pdf.

When the Ham Video transmitter will become operational, it will be used for ARISS educational school contacts. Video will be for downlink only. Uplink will be VHF FM audio. The Ericsson transceiver onboard Columbus will be used for reception onboard. This cross band and double mode operation is called Ham TV. Ham Video is the name of the DATV transmitter.

Chi ha o avrà tutta l'attrezzatura necessaria alla ricezione ora avrà ancora di più da divertirsi. Io personalmente mi accontenterò di andare da IK1SLD e sbirciare  :miiii: :miiii:

[TITANO]

Grazie r5000 per le info preziose,,,mi mettero' in ascolto e chissa ' ,puo' essere che qualcosa si becca.

[ale_nest]

Per me è appena terminato il passaggio con VX-6 e antenna SRH771 40cm

Resoconto:

- 143.625     Ascolto forte e chiaro con picchi a S9;
- 130.167     Stessa trasmissione che a 143.625 ma ascoltata al massimo a S5 (forse perché l'antenna non era giusta per la frequenza);
- 121.750     Nulla (forse perché l'antenna non era giusta per la frequenza);
- 121.500     Nulla (forse perché l'antenna non era giusta per la frequenza).


Comunque per la mia radio la sensibilità è:

- 1.5 μV tipico per 10 dB SN (108-137 MHz, AM)
- 0.2 μV per 12 dB SINAD (137-140 MHz, FM)
- 0.16 μV per 12 dB SINAD (140-150 MHz, FM)


Quindi non posso avere speranze sui 121 MHz senza super antenne dedicate, che non ho.
Già sui 130 MHz ascoltavo, forse perché escono "forte" e non con i mW.

[TITANO]

La prossima verso che ora passa ?

[ale_nest]

La prossima verso che ora passa ?

[...]
i prossimi passaggi utili (15:53, 17:30, 19:21, e forse anche alle 20:44)
[...]

[Alinghi]

Ma i prossimi passaggi passa un bel pò più lontano.
Alle 15:53 è passata ancora sopra L'Italia, ora il prossimo passaggio sarà nel Nord Europa, Praticamente sopra la Germania, e quello dopo  credo ancora più a nord.

Ma i prossimi passaggi passa un bel pò più lontano.

Quindi?
Si riceve bene uguale. Forse con una finestra di tempo ridotta per chi è nella zona periferica del footprint (tipo Marocco, Tunisia, Algeria, Libia e estremo nord di Finlandia e Svezia) ma comunque ascoltabilissima da tutta Europa.  :up: :up: abbraccino abbraccino

Idem per il passaggio delle 19:12  :dance:

[ale_nest]

Passaggio delle 17:30, stesse condizioni del precedente e stessi risultati del precedente. Identici.

Invece il passaggio del SO-50 mi è stato particolarmente negativo, anche in direttiva al massimo era S1. Boh.

[TITANO]

OK grazie.  :birra:

[diegooz]

Li sto ascoltando ora su 143625 con la QFH finita di costruire stamattina, riceve 9+20 alla grande, confronto i 7-9 della discone! (poi non so quanto sia preciso il s-meter ma comunque va meglio della discone anche se è in una posizione un po più bassina e un po coperta da un lato, per ora.

[TITANO]

Bravo diego,sempre attvo a sperimentare e a provare. Hai un ottimo spirito di radio.!  :birra:

[r5000]

73 a tutti, ottimo! vedo una bella antenna e Alessandro ha sentito pure la comunicazione dalla tuta, io ho ascoltato a pezzi ma è tutta colpa del posto dove ero, la rete dei pc irradia tanto da avere portanti sparse fino alle uhf e solo cercando col gommino ho sentito a tratti ma sono certo che il segnale arriva, il dubbio era la frequenza usata... se ho letto giusto sono meno di 0.5 watt per le tute e 5 watt per la ISS, 400km si fanno con i milliwatt in portata ottica...

[ale_nest]

Io ho lo schermo LCD del PC fisso che mi fa fondoscala a 430-450 MHz quando lo accendo.
Una pace indescrivibile quando spengo tutto. Addirittura il router WiFi fa casino sui 420 MHz.

Gli altri passaggi poi non li ho potuti più ascoltare, magari qualcun'altro sì.

Sul fatto che i mW bastano se c'è portata ottica concordo ma serve anche un'antenna almeno degna e se poi si cerca di ricevere con radio non dedicate la cosa si fa ardua.  marameo marameo

Urge un'antenna dedicata per fare ascolti come Dio comanda, maledetta pigrizia.

Ieri alle 17 circa sentita conversazione in russo.
Scusate ma come radioamatori è possibile tentare il contatto con la ISS o la frequenza 145.800 è riservata alle scuole?

Stamattina sono pronto con la quadrifilare montata ieri sera su una canna da pesca e alzata sopra al tetto, il vicino mi vede e mi chiede: "che devi fare...parlare con gli ufo?"
Risp:"beh quasi dai, devo ascoltare gli astronauti che domani mattina passaqui qui sopra..". ha fatto una faccia ahahah! poi gli ho spiegato per bene tutto per non farmi prendere per scemo hahaa.

[diegooz]

Questa volta ho ricevuto poco, poi penso abbiano avuto qualche problema con la trasmissione da terra, perchè ho sentito che dalla iss Luca Parmisano diceva di sentirli meglio dopo essersi spostati di frequenza credo.
Comunque con la verticale non ricevevo nulla e non si apriva nemmeno lo squelch, con la quadrifilare invece ricevevo abbastanza bene e non era proprio libera. La prossima volta proverò mettendomi in mezzo ai campi in modo di avere più orizzonte libero possibile.

[norge]

73 a tutti,
Ricevuta la trasmissione dalla ISS questa mattina ore 9:19 locali. Purtroppo il segnale era scarso,  tant'è che anche Luca Parmitano ha avuto difficoltà nel collegare la scuola in Svizzera. A breve vi invierò il link di YouTube dove guardare il video.

HamTV Bulletin 2
September 10, 2013

Ham Video - EST and Simulations

Ham Video Commissioning preparation is progressing. An EST (Experiment Sequence Test) has been performed 28-29 August and Simulations tests were done 5-6 September 2013.

The EST consisted of a series of tests, mainly of the ground segment. For the Commissioning, the VLBI (Very Long Baseline Interferometry) station of the Italian Space Agency (ASI), located near Matera, southern Italy, will be used for receiving the DATV signals from the ISS. For the EST, the IK1SLD ground station, situated at Casale Monferrato, northern Italy was used. IK1SLD is one of the ARISS telebridge stations, fully equiped for VHF and UHF. It was recently upgraded for S-band with a 1.2m dish, feed, downconverter and precision tracking motors.
For the EST, a very low power transmitter, installed in the shack, generated signals on the Ham Video frequencies, transmitting a DATV recording at 1.3 and 2.0 MS/s and FEC ½. The DATV signal was received and decoded by the IK1SLD station and webstreamed to the BATC server.

B.USOC (Belgian User Support and Operations Center – ESA) conducted operations. B.USOC and EAC (European Astronaut Center – Cologne, Germany) specialists operated from Livorno at Kayser Itallia's laboratory, where a Ham Video unit, the so-called EBB (Elegant BreadBox), is operational. Parties involved were interconnected per teleconference. At Casale Monferrato, Claudio Ariotti IK1SLD and Piero Tognolatti I0KPT produced, received and webstreamed the signals in the different configurations as requested by B.USOC. ESA and ARISS observers participated to the EST teleconference. After debriefing, the EST was declared successful.

Simulations were done differently. B.USOC supervised from their offices in Brussels and ARISS responsibles Piero Tognolatti I0KPT and Jean Pierre Courjaud F6DZP operated from home. The simulations were done in the Columbus mockup at EAC, where a non operational Ham Video model is installed. This box is used for astronaut training on Ham Video. A KuPS power supply was also used, as well as a camera similar to the one onboard Columbus in space. Ham Video transmissions were simulated in the different configurations (frequencies and symbol rates). A view of operations in the Columbus mockup was webstreamed to the participants. ARISS operators simulated reception as if thery were at the Matera ground station, taking into account expected timing between AOS and LOS. They signaled AOS and requested "crew" at EAC to transmit in different configurations, according a pre-determined scenario. At LOS, the test stopped and results were commented.
Four "passes" were simulated this way, using both ARISS antennas. An important goal of the simulations was to check the efficiency of communications between ground and "crew". Commands were initiated by ARISS operators (supposedly from Matera), received at B.USOC, relayed to the Columbus Control Center at Oberpfaffenhofen near Munich and uplinked to "crew" by EUROCOM. The European ISS Control Center is called Col-CC and its spacecraft communicator's call sign is EUROCOM. The Simulations were conducted successfully and lessons were learned for gaining time on transmitting commands. This is important considering the limited 8 minutes contact time during real Commissioning.

ARISS proposed to use our VHF uplink capabilities to "crew" for the Commissioning. This was not acceptable with regard to ESA's commissioning protocol.

Presently, ISS pass predictions for Matera are computed for several weeks starting mid October, The Matera VLBI activities are to be taken into account for determining usable passes. Four passes will be needed to fullfil the Commissioning requirements.
Ham Video Commissioning activities will be decided by ESA and NASA ISS Operations. Hopefully the Commissioning will be planned during Expedition 37. We will keep you informed.
