Spaceblimp-5 Launched: July 9, 2011

Summary

This time we were going for altitude. By using a larger balloon, hopefully it will burst at a higher altitude, 120k feet predicted. (117k actual. Within 3%. Not too shabby!!)


The launch site was: Strasburg VA, in a open area near the town on Rt 11, near the I-81. Lat: 38.9968 N Lon: 78.3508W

Or follow along at home! There are two radios on board the blimp that transmit out the GPS data:

  • The primary radio is tied to the GPS and transmits out to a network of amateur radio enthusiasts who then pass the location information on to get mapped here: APRS.fi. We also are running some custom software that passes this data on to a Twitter account (once per minute!) which you can follow on your phone: DC Spaceblimp Primary Twitter Feed. (Click the link in the Twitter to pull up a map!)
  • The secondary radio is actually a GSM cell phone module, and will broadcast its data when in range of a cell tower. It will be broadcasting both GPS data for tracking, and a lot of the sensor data for science. You can follow that Twitter feed through Society Of Robots Twitter Feed.
