Fantastic work Howard, and thanks for sharing the details.

Contratulations on your series of flights Howard.  
Watched the flight on APRS and knew you wanted to avoid trees-sorryEmoji
Hope your recovery goes well.

BASE 115 flew today.  Flight ascents were a little bit faster than predicted.  I am afraid that my students have adopted an overly conservative approach (they have heard about Mike Manes :)) and we gave the balloons a little too much gas.  We did have a nice separation of the tandem balloon, although it was 10 km instead of 15 km.

If you are following the flight on amateur.sondehub.org or aprs.fi, you are aware that the radios are still beaconing happily from the 30 m tree top behind a very nice home in Johnson County, Indiana. The property owner was at home and very agreeable.  Fortunately, he has an arborist and a tree service.  Recovery should be completed next week.

We are out of time, balloons, and gas for our summer flights.

Thanks again for your support,

BASE 114 Successful- BASE 115 tomorrow

B_._
BASE 114 showed a successful cutaway at the predicted altitude of 15 km.  Easy recovery in a soybean field adjacent to the property owner's home.  He was amazed that we had tracked the descent  into his field and my students walked directly to the payload.

BASE 115 will fly on Saturday, July 30 from the roof of the Julian Science and Mathematics Center at DePauw.  It will be a tandem 600 gram set of Kaymont balloons using hydrogen.  Initial ascent will be around 5 m/s (1000 ft/min) with a transition at 15 km (50,000 feet) to a rate between 1.5 and 2 m/s (300-400 ft/min) to burst around 30 km (98,000 feet).  

Ascent rate may be tweaked in the morning before launch to increase the likelihood of avoiding heavily wooded areas.

Thanks for the support,
Howard

BASE 114 and 115

BASE_DePauw
 

We will be wrapping up our summer flights on the next two days.

Friday, July 29 at 8:00 AM EDT (1200UTC) we will do a test flight on the reprogrammed balloon cutdown device.  The intention is to cut the balloon off at 15 km (50 kft).  The 350 gram balloon will be helium filled and the call signs should be W9YJ-14 and W9YJ-13.

Saturday, July 30 at 8:00 AM EDT (1200 UTC) we will do a flight of the Geiger array with a slow ascent from 15 km until burst.  If the Friday flight is successful we will climb to 15 km at 5 m/s (1000 ft/min) then climb at 2 m/s (400 ft/min( until burst around 30 km (98 kft).  If Friday's cutdown is not successful, then it will be a slow climb from the surface at 2 m/s (400 ft/min)  Call signs on Saturday should be W9YJ-11 and W9YJ-13.  

Both launches will be from the roof of the Julian Science and Mathematics Center on the DePauw University campus in Greencastle, Indiana.

Thanks for your support,
Howard

The datasheet shows -20c as it’s minimum operating temp and 25km as it’s max height without a firmware update for space operations. I would expect the button battery as mentioned above!

Hi

An interesting thing happened on our SABRE-31 flight yesterday.  Our VE5AA-12 tracker gps failed at or near 39986 feet.  The tracker is using a GT320FW(AS) that's been flown before and worked fine.  Has anyone else seen this behaviour with this GPS?

Mark,

Yes, I changed back to feet for APRS reporting.

The altitude cutoff device shut down before reaching 15 km.  The change at 26 km occurred when the first balloon burst.  Not quite the plan, but still an interesting flight.  We brought back both balloon necks to the ground.

Thanks for the grafana dashboard.  It is wonderful.
