Non-Lyngsat satellites

Some information on ) Low-Rate Information Transmission (LRIT):

Edit: Ouch! Looks like these aren't hobby receivers. Seems like everything I found was in the $4,000 + range:

not sure if it's signal bleed or not...

but there are a couple of things that look like they are showing up on Goes 12 and 13. Think the channel that showed up was NewsLive1. I wouldn't try going after NOAA or other satellites that seem to have n/s movment, just the birds that stick around down by the equator.

Newsone Live is a feed on IA-8 (Formerly IA-6)

That's what I was afraid of. I guess the Goes are all the tps with the data only feeds.... oh well - it was worth a try.

It certainly was.

If you find out more on what equipment you need let us know.

http://rsd.gsfc.nasa.gov/goes/text/goesnew.html has a list of GOES long term planned launch dates, operation dates, and retirement dates. Dates go back to 1994 and up to 2040.

Interesting link http://en.wikipedia.org/wiki/GOES

hmmm...

wonder if the LIRT stuff is sort of like DVB-RCS?...

http://en.wikipedia.org/wiki/Satellite_Internet_access

If so, would it be possible to tune in a weather satellite and use some sort of modem to hook the incoming signal to the computer... really pointless even if possible since they put live satellite images online anyways...

There is mention of Anik E1 earlier in this thread. You will find AMC-16 there doing Circular in the KuFSS band for DiSH Network. 1 FTA clear channel on the entire satellite.

The analog image downlink from GOES is at something like 1690 MHz. The typical amateur setup is downconverter -> wideband receiver -> sound card. Typical downconverters output 137 MHz so as to be compatible with custom receivers used for the polar-orbiting satellites. (A common emergency-services scanner, even if it includes the 137 MHz band, doesn't have enough bandwidth to deliver a good image.)

I don't know what frequency the digital data, if any, is at, but I doubt it's Ku.

I know that this is starting to diverge from a FTA thread, but could I ask what sort of antenna and receiver would be needed for this? (Maybe this is still considered Free to Air?) If the 4000 dollar receiver is standard, I think that I might rapidly loose interest.

I'm not sure... as far as I can tell, the weather satellites send out free signals, as you don't pay a subscription to pick them up, and they are free unencrypted signals from satellites. Not sure it's really called "free to air" since it's data signals... they aren't encrypted, just not normal mpg2 signals so receivers can't read what's there even though they see the tps and some signal activity

I too am interested in what antenna/equipment you need. I'm guessing (just a big guess here) that you could use the fta boxes to find the birds (since there are tps that the fta boxes do pick up on these satellites) and somehow get the signals to come off of the dish in to a computer to read the data... but am clueless as to how you go about doing all of that.

Another post somewhere said something about using some special soundcard or something?

Maybe you could somehow get a video card in to the mix, pulling the signal in to the computer through a coax cable... read the data in the computer, change it to ntsc/pal video signals like what you see on weather channels on tv, and send that back to a tv through another (or the same) video card.

(I'm sort of in to moving signals from computer to tv because I'm sort of in to 3d animation and stuff and at one point wanted to get stuff sent to tv to record to vcr to put on demo tapes to send out with resume' to various potential employers... never got a real demo reel together yet, but still have the equipment at the moment)

I'm not sure what you'd do with the signal once you get it to the computer... I'm guessing there's some sort of program out there you can use to read the data from the satellite and actually convert it to an image. It looks like Goes and some of the others use ftp in the mix somehow...?

wonder what all you could pick up with one of those dishes:

LOL

 

[mastermesh]

http://www.uvm.edu/~swarley/wx.html indicates 137mhz antenna but I'm guessing that's just for audio??? XM???

http://froogle.google.com/froogle?hl=en&lr=&q=137+MHZ+ANTENNA&sa=N&tab=wf


I'm suspecting you might be able to use a dish instead since it can aim directly at the satellite... the trick would be getting the signal from the dish in to a format that humans can understand...

Froogle seems to indicate that the audio weather satellite receivers might work with xm and be cheaper than the visual ones... visual ones look pretty pricy.

master, in your research, have you researched this site? Did you see this thread?

it may be of some use for you.

[mastermesh]

didn't see that.

Thanks.

http://www.google.com/search?hl=en&q=Novra+S75&btnG=Google+Search brings up

http://www.unidata.ucar.edu/support/help/MailArchives/idd/msg03292.html which indicates that special receiver costed about 320.00 in 2004. May be cheaper nowadays?

random googling...
Installing and Configuring the DVB-S Receiver:

Google for NOAAPORT ingest Computer http://www.google.com/search?hl=en&lr=&q=NOAAPORT+ingest+computer&btnG=Search

Wouldn't it kick butt if some of the fta receiver makers somehow eventually managed to add all this conversion stuff inside of the receiver boxes, so that all you had to do was tune in just like you do for other satellites?

In March of 2005 the National Weather Service changed the transmission method for its NOAAPORT data stream to Digital Video Broadcast via Satellite (DVB-S). For SSEC NOAAPORT SDI customers there are significant hardware and software changes that are necessary in order to continue receiving and processing the NOAAPORT data stream. In a nutshell, these changes involve the purchase of a DVB-S receiver and a second network interface card for the ingestor computer, the installation of software to read and process the output of the DVB-S receiver, and the installation of the LDM software which will be used to make the data available remotely.

Wow, I'm really starting to get lost in all of this information. It seems like a lot of the links go into detail on this and then fizzle out before actually showing results(or maybe I'm just getting confused?). I was really interested in link about using c-band on amc 4 with a twinhan card....It got to the point where raw data was actually obtained and that ended the experiment!
I still think it would be cool to obtain real time weather transmissions.
Is there anyone actually doing this right now?

 

[mastermesh]

and more importantly, can you do it on a cheap budget? I noticed that the old drd420re satellite receiver sitting in my attic collecting dust has a "low speed data" jack. Wonder if can be used to get that incoming data from the pansat through the if loop and then be exported to a computer? Doubt it, but you never know.
