30km高空,佳能家用DC A570配合破解的固件自动控制摄影,要注意保温,虽然低温对CCD工作有利,但是那个高度的气温足够干掉你的电池。我引用的这位用GPS和无线电连接,广播自己的位置,人不可能操纵气球的飞行,但是可以开车追踪下降的气球。
Whew,I do not have a write up on the process. While it isn't terriblycomplicated there is a lot to learn to make it happen. We used amateurradio connected to a GPS receiver to report the balloon's position(s). There are other methods using different radio devices but it is allbasically the same procedure.
In the U.S. you can fly an unmanned, untether balloon that weighs less than 6 lbs. without and formal permission.
This online book, Near space, by L. Paul Verhage is a good primer on how to do it. http://www.parallax.com/tabid/567/Default.aspx there are many other online resources as well.
Edge of Space sciences also has a lot of information on their program. http://www.eoss.org/index.html
Don'tlet an Amateur radio license keep you away from doing this. They areeasy to get and the test questions can be found online. http://www.arrl.org/
Using amateur radio you can get the flight's path to be placed live online using APRS. http://www.aprs.org/ The flight from where these photos were taken can be seen here: http://aprs.fi/?call=kc0gpb-11&dt=1258934400&mt=m&z=11&timerange=3600
CHDK comes in to play with an intervalometer (I grabbed a script off the EOSS web site linked above under hardware>camera).
There are a lot of challenges in a HAB flight but that just makes it more fun.
I hope this helps.
Pete
