Trying to do an "Energy Budget" with my low-power research background. Please help with the balloon angle.
.1 - 1W Balloon height adjustments
.1 - .5W Flight tracking, control and management
.5 - 2W RF power and conversions (balloon-to-ground)
.5 - 2W RF power and conversions (balloon-to-baloon)
1 - 2W Packet routing, processing and baseband processing
Essential missing insight: how to they lower/rise the balloons and deflate/inflate them? With 100days service time you cannot simply vent gas. So a pump and compressor is needed?
- 7952 13y agoIf you just have a radio repeater you could ditch the packet routing.
- mtdewcmu 13y agoDid it say somewhere that they last 100 days? That number sounds familiar, but I couldn't find it just now when I went back to the site. I wonder how far the balloons would travel during those 100 days. As you can tell from the video, they're going to spend most of their lives drifting over the ocean. Edit: there are more details here: https://news.ycombinator.com/item?id=5887330 https://news.ycombinator.com/item?id=5887330 Apparently they circle the Earth every 14 days.
