I recommend using the LiftWin program rather than looking at sounding charts (the chart, I believe, assume a specific payload weight that probably won't match...
Thank you, Paul. That is a clear explanation. However, my initial question relates more to which size balloon I should purchase - i.e. a 1200, 1500, 2000 or...
If you're flying less than 12 lbs., you can't go wrong with a 1200g balloon - this will get you into the 80-95 kft range (closer to 80 at 12 lbs, you might get...

The new (smaller) stainless steel container is working like a champ. It allows trhe vacuum pump to draw a good vacuum and then it holds it well. Over this...
No - I just want to know which size balloon will hold enough gas to lift a given payload weight without overpurchasing a (too big) balloon for a typical...
Paul recommended Hank Riley's LiftWin, and so do I. There's link to download it on www.eoss.org - just hit the search for "liftwin". This handy little app...
The correct answer is to use LiftWin before you buy. You didn't mention your payload weigt, so Mark was guessing 5 - 10 lb. If it's really just 2 lb, then you...
Thanks, Mike, and all, I now see where our disconnect is in my questions. You all were answering me just in a way I didn't anticipate and I was missing your...

I just got word from Garmin that they don't do tours. So unless we have a Garmin emoployee on the list that can work something out, there won't be a Garmin...
You are going to find a lot of that in high tech industry. The US export control laws (EAR and ITAR) have gotten so strict that even showing a factory to a...
I don't think we're in Kansas anymore. Aside from Zaggle, what online t-shirt companies have worked well for people? I got 55 of the BalloonSat Mini PCBs and...
Attached are copies of the GPSL 2009 logo and first draft of the media announcement. I'd like to get the logo on the SuperLaunch website. Please look over the...
I don't think KU has said anythign yet, so I will. KU Aerospace engineering is planning a launch to test two tandum balloons. I'll donate a tracker, so one of...
Might mention how many balloon groups are expected and/or mention how many groups attended previous GPSL's. How long GPSLs have been taking place might be of...
We have a launch Saturday 3-7-2009. Flight Information Flight: STO29 Flight Number: 145 Origination: Depaul University Flight Locaction: Chicago IL. Flight...
The XBS group wants to launch a single payload on two side by side balloons. I'd encourage them to bypass that route and just launch a single larger balloon. ...
The weather isn't cooperating, so the XBS launch for this weekend has been cancelled. Right now the launch is planned for March 21st (I'll still be on spring...
I agree, unless they did like we did with the seperator bar. That was awesome while it lasted,, cool thing tho was the recovery for it came down on the single...
We had good luck using two 3000 g balloons when we tried for the altitude record on UX-3. They were very underinflated though, and only carried a 6lb payload....
The UAH Balloonsat flight is complete....payload landed near Fairmount, TN just north of Chattanooga, TN at: 35.2032 85.3085 .... it landed in the front...
Yeah, landing under a semi-filled balloon can be real neat - unless it's windy - in which case, you could log two launches when the bottom of the payload...
Dear friends, Has anyone used the smart beaconing function on the TinyTrak from Byonics to transmit more frequently when stationary and less frequently when...
Not that, but I'm experimeint with the MicroTrak 300 and the ability to switch between two configuration settings. I have the flight computer set a pin high...
Good evening Howard, This won't answer your question about the TinyTrak, but for future reference the OpenTracker+ from Argentdata.com is able to switch...
