Hello
Kitesurfers spend a lot of many for devices that can measure their jump heights (for example https://usshop.woosports.com/ , https://store.xensr.com/products/s/ ). These devices have accelerometers and gyros on board to measure the jump heights (and airtime, distance, gforce of landings and more). There are leaderboards to compare your jumps with others on the internet : https://leaderboards.woosports.com/ . It would be superb to have an app for the garmin watches (fenix 5, vivoactive 3 and more) that can do the same - xensr just made an app for the apple watch. The math behind it is not very simple!
I think a much easier way to measure the jump height, would be to use the barometer (ambient local pressure) difference at the beginning of a jump and at the highest point (for kitesurfer on more or less flat water anyway). I don't know how frequently the barometer (ambient local pressure) can be read and how accurate it is, ten times a second (10 Hz) should be enough I think and if you jump 1 meter high of the sea then the pressure should be 13 Pa (Pascals) lower, for 10 meters 130 Pa which is 1.3 hPa lower.
Is anybody able to program something like that?
If not I might try it myself. Might need some help - the last simple programs I wrote on a Commodore VIC 20 in BASIC and saved on compact cassettes ...:eek:
