Free (As In Beer) Satellite Track Software – GPredict

So after ARISSat-1 was deployed, I have been trying to receive a signal from it. Specifically SSTV signals. I haven’t been very sucsessful. For one, I haven’t been able to be at the radio when it makes a pass because of work and family commitments. I’m hoping this week, I’ll have more time to sit down and be there to listen for. But the first thing is, I need to know where it is.

I took a look at some of the tracking software out there for my Mac and found that there is only really one program that I could find for the Mac natively, that was “fully” featured with all the bells and whistles. But it was pretty steeply priced for me at $98. I decided t see what else was out there for free. The only one I found that I liked, was Gpredict. It’s written for Linux, but there are ports for it for Windows and Mac, and it’s open source, so it’s free.

The only draw back was, it wasn’t native, so I had to install from source or use MacPorts, a project that ports open source Linux software to the Mac platform, since Mac OS X is based on FreeBSD. The install took me about an hour because of all the dependencies needed for GPredict. MacPort installed them all with no problem.

So after some false starts and finally reading some more info on it, I managed to get it running on my Macbook Pro. After I ran it for the first time, it saw that the info for the satellites was out of date and asked to do an update, giving me the option to do it online or through a file I downloaded.

Gpredict supports fast and accurate real-time satellite tracking using the NORAD SGP4/SDP4 algorithms, No software limit on the number of satellites or ground stations and Radio and antenna rotator control for autonomous tracking.

After uploading and doing a little more research, I was able to find ARISSat-1 on the list, under RadioSkaf-V. Once I found it, I was able to track it no problem. Now, it’s just a matter of having the time to do it. In the meantime, I encourage you to check out GPredict, and try it out. Since it’s free you’ve got nothing to lose.

But if you also have a suggestion for Mac satellite tracking software, please, share it in the comments, and share any experience you have with GPredict.

LHS Episode #021: OSCON 2009 Update 2

osconHere is the second and final installment of the special OSCON update for Linux in the HAM Shack. In this episode I examine the second half of my trip to San Jose, California, and the O’Reilly Open Source Convention. I talk about sessions I attended dealing with subjects as diverse as patents and legal issues, processor speed, cloud computing, users as Open Source advocates and, yes, evening programming in Klingon. I also take a trip through The Tech Museum of Innovation, an institution run entirely using Open Source. So sit back and enjoy this special report from OSCON and as always, thanks for being a loyal listener to the program.

Don’t forget to leave us voice feedback or questions. We’d love to put you on the air. And we know how ham radio operators often have the gift for gab. So let it out. Don’t be shy. Linux in the HAM shack wants YOU.

LHS Episode #019: OSCON 2009 Update 1

Hey, eosconveryone. I’m spending the week in San Jose, California at the O’Reilly OSCON conference. Since OSCON is an Open Source convention and has a lot of information about Linux and Open Source, I thought I would bring our listeners a couple of updates from the con. We’ll call these supplemental episodes of Linux in the HAM Shack. The second one will be along in a couple of days. Hopefully this will provide a little insight into the conference experience, and I’m going to share as much useful information as I pick up with our listeners. Thanks for downloading, and look for our next live podcast on Tuesday, 7/28 at 8:00pm CDT.
