Where can I find a good tutorial on "how to" monitor/decode the many and ever increasing beep boxes up there. Then, what do you do with data? Also is there a place where the keps for these little gizzmos can be easily accessed and downloaded into Satpc-32 work them till they drop 73 Bob W7LRD
Hi Bob,
I don't think we have any "beep boxes" out there. If that is what you call cubesats, nano and picosats, I would highly discourage you to even look at them. Now having said that, let's assume you want to receive data from these satellites, there is NO one tutorial. On the other hand you could write one :-)
It is all about you doing your own homework, compiling information, learning along the way and using resources like Mike Rupprecht's beautiful website: http://www.dk3wn.info/satellites.shtml for more information.
What you do with the data is totally up to you. Many of us help these teams and forward telemetry information to them. Some teams have developed special software to decode the data and allow us to actively monitor the status of the satellite and any experiments.That's the beauty of this hobby that we can do some technical stuff, learning about the satellite etc. and are not reduced to mindless rag chewing with someone who could care less what my cats name is. Actually I only have a dog
Regarding the keps, maybe you should look up all the great stuff that comes out of Celestrack and look at: http://www.celestrak.com/NORAD/elements/cubesat.txt and that is just one source (Google here I come....)
Hope that helps,
Stefan VE4NSA

I'd love to get involved in that, and indeed I think a lot of the current thread was spawned by a discussion of tracking the F-1 sat. Unfortunately, there is only a Windows binary available of this software. I know amateur radio is a technical hobby, but I haven't the inclination to be a computer nerd as well, and I haven't the time, inclination or money to buy another computer and a copy of Windows and all the expensive training courses.
I do wonder if having the telemetry in an unpublished format counts as using a "secret code"?
Looks to me like the program will decode the packets right on the client software. Packets copied, decoded. Then, there's always the documentation on the web. Isn't this what you say isn't there?
What is so secret?

Not much help if there is no way to run the client software. It's Windows-only. I don't know anyone that uses Windows.

You're right, that one has it. Many of the other projects don't appear to publish their spec, though.
Well...

Hyperbole?

Hi
There are also telemetry decoders available for various satellites on the Carpcomm website. For example:
http://carpcomm.com/satellite/fspace1 http://carpcomm.com/satellite/swisscube http://carpcomm.com/satellite/csswe http://carpcomm.com/satellite/horyu2
Just click "Submit data", enter the morse characters or hex data frame that you've received, and it will be decoded and the latest telemetry values will be displayed on the page for everyone to see. We're continuously working on adding decoders for all the new satellites.
Regards, Timothy HB9FFH http://carpcomm.com/

Well, the modern ham does need some level of computer expertise, though not necessarily programming. You still have a few options. The software may run under WINE (which runs on Linux and OS X) - if this is the case, you're in luck, you don't need Windows, or there's a number of virtual machine options - both free and commercial that you could load a copy of Windows in. Virtualbox is a free option, VMware is a commercial one that is no cost for Linux (VMware Server), some cost for Macs. Parallels is another commercial Mac alternative. Of course, with this approach, you'd need a copy of Windows to install into the virtual machine.
Sadly, a lot of ham radio apps do require Windows. I have the same issues, but VMware Fusion (with Windows 7) on the Mac gets around that quite nicely.
