openSPOT in space!

Post by K6TDM » Tue May 30, 2017 4:44 am

I don't know if this is has been done before.
Details below.

On June 10, 2017 at 9:00am, Arizona Near Space Research in conjunction with the Prescott Arizona hamfest will launch a high altitude balloon containing a high speed data link at 5.8 GHz and an OpenSpot. Hams in the surrounding area of Prescott and Phoenix are encouraged to tune their DMR radios to 439.00 MHz and try making contacts via the OpenSpot. The ground station in Prescott will primarily be listening on the Arizona talk group 3104. Hams in any part of the country are encouraged to try and reach the OpenSpot via the Arizona talk group as the OpenSpot on the payload will be connected to the internet via the 5.8GHz link. To help coordinate contacts the ground station in Prescott will be monitoring the Arizona talk ground via its own OpenSpot.

The 5.8GHz link will provide data connectivity to the ground that will be used to stream live video from the payload and connect the OpenSpot to the internet. The payload uses a Raspberry PI to collect raw video, and a GPS allowing coordinates to be posted directly to APRS.fi. The payload call sign will be WB9COY-11. Hams can look for WB9COY-11 on APRs.fi and click on the link in the info box
to view the payload video via their web browser. The direct link to the video is https://stream.live/az_ascend.

Despite some difficulties the launch was a success. The systems worked great, especially the openSPOT and the streaming video. Details to follow. Watch for a report on this thread coming soon.

Space beyond the atmosphere of the earth ? I think not.

Depends on the definition of space. At one time it was 50 miles high, I think it is now 100 miles.

Getting a balloon that high is very difficult, the balloon swells as it rises and eventually the skin splits and the payload falls again.

100 km
There is no firm boundary where space begins. However the Kármán line, at an altitude of 100 km (62 mi) above sea level, is conventionally used as the start of outer space in space treaties and for aerospace records keeping

53km is the max altitude record known for a special balloon, but usually 35km max for a AR balloon well under the space cap.

So openspot at high altitude or ' near space ' is more appropiate. the balloon always remains in our atmosphere, and not beyond where space begins officially at 100km.

However you never know if you can get on on the next satellite launch.

Looking for those details to follow :)
Curious how it actually went and what was learned etc.

Thanks!!
I feel more like I do now.

That's why the organization is called "Arizona NEAR-SPACE Research".
The highest balloon that I'VE seen go before burst was over 100,000 feet.
