Thanks for the links. The sparton is quality. If you really want to do things right, spend the money on a good INS. As for project ariadna…i question anyone making big claims and offering no technical specifics. Also, the website seems to be owned and run through UAE, which not a red flag on it’s own, but a finland based company with a site owned by the UAE…seems fishy, lol. anyway. awesome if it’s legit…but, awfully over produced videos.
now as far as dead reckoning with the pixhawk…i wouldn’t. you are double integrating inducing horrible drift…the ekf isn’t going to do much for you without another sensor giving you position estimates. dvl, vision, something, lol. second everything Jacob wrote.
