Exploring ideas to speed up SSDV using the notion of ‘known images’.
First off this is just an idea I had while messing with the Raspberry Pi and SSDV and wanted to put it somewhere to start a discussion.
Although everyone's live SSDV pictures are different, at the same time they are equally similar over a certain altitude - One person's image of the earth at 80,000ft isn’t that different to the next. Sure the angle might be different, but generally they are similar. Could we use this fact to our advantage?
Could we create a set of ‘known images’, (categorised by altitude?), in order to have a reference point before each transmission. These images would be preloaded on the Pi before launch and also be on the central Habhub server. A general process could be:
