Balloon Experiments with Amateur Radio

Curvature

Several amateur radio operators came together and started launching high altitude balloons with experimental amateur radio payloads. They nicknamed these balloon experiments with amateur radio as BEAR. A balloon carrying the payload along with an APRS tracker is released and reaches a height of 117,000 feet. At that altitude, the earth’s horizon is 460 miles compared to 2-3 miles at ground level.

On February 11, 2012, they launched BEAR-9 carrying a 4×5 camera as the payload. This large format camera resulted in spectacular pictures from the edge of Earth’s atmosphere. Check out the BEAR web site for more information.

  1. I’ve been watching these high altitude balloons for a year or so and this one take the cake. I love the fact that it toted up a 4×5 film camera. Is a 8×10 next?
