Next weekend, if everything goes well, a 15x30cm carbon deck will fly onboard HAPS-1 -http://www.pegasushabproject.org.uk/wiki/doku.php/missions:haps:haps-1
One end of the deck will be the flight radio, the other is my responsibility, a single camera (Powershot A560 ), stand alone GPS logger (to 18km), and a small wide angle mirror so the camera can see the payload, the chute and the envelope above. Still working on a hacked firmware for the A560 - but the intention is every minute will include 15s of video, and then 5-10 stills in fairly quick succession - with the hope that the rotation of the balloon will give us some mosaics out of each section. More details, some photos etc, later in the week. |

Well this goes back to all those sims I did back in the old UMSFB thread. With one camera I think as is was about perfect. If I got to add a second camera then for sure it needs to point downish. Thinking back to my sims, I would suggest having it in 'portrait' orientation with the lower edge close but not quite nadir (centre of image about -50 degrees elevation (FOV is ~53 degrees, so this would capture ~-24 to -76 degrees elevation in level flight)
Maybe it's time to break out that sim code again now we have more data on how the balloon really behaves. -------------------- |
