Hi,
·
We are a group of students working on balloon satellite project.·Our goal is to build communication system that will transmit data from sensors and images taken·by the·payload of the balloon to the ground.·Estimated distance will be up to 80,000 feet. Could anyone help us to find out if·some transmitter/receiver·can be·suitable for our project and at the same time compatible with the Basic Stamp?
·
Thank you

    What level of students? 80,000 feet is rather high: 2/3 of geostationary satelite orbit.

    Anyway, in the customer applications section of the website, there is a download howto that will tell you everything that you need to know about High Altitude Balloons. You almost certainly won't be able to transmit the pictures, rather, you'll have to store them onboard and transmit the location, and recover the BS2.

    As SLRM said, 80,000 feet is high. But, it is apparently very do-able. Take a look at this 103,000+ success: http://www.parallax.com/tabid/569/Default.aspx

    Another site one might watch is the Parallax web site itself: http://www.parallax.com/tabid/565/Default.aspx

    These are incredibly interesting projects. I suspect (total wild guess) that they were expensive, as well.

    Good luck to you and your fellow students!

    You'll also need 1 or more cars with trackers so that you can recover the device, and be willing to file with the FAA.

    Er, either you're referring to something I don't know about or you misread something: geosynchronous orbit is 22,500 _miles_ in altitude. There are quite a few readily available balloons designed for amateurs to reach 80,000+ feet:
