  • I would suspect they already do some of this as even with the "Drunk man" or some of the crazy tracks we've seen, the distance isn't nearly as off as the plot would suggest.
  • Can‘t tell details because it‘s related to my work but look for kalman filter for example.


    It will probably behave a little like in car navigation systems and how they keep track in tunnels and such. They use the pitch and yaw sensors in the car combined with steering angle and vehicle speed to estimate the position of the car compared to the last GPS location. The watch could use the accelerometer to achieve something similar. That is what it does in Ultratrac mode isn't it? So basically it could use those routines combined with a fast GPS update rate to determine the location.

    No you can't because music player features are more important than you "special" customers over there :) :) :)

  • Following on from the APAC Question above, I have the Marathon this weekend and would like to see if I can deploy the GPS Update only on the APAC Version (as discussed in the other post)

    No restart on my watch neither.
  • it is sad to see how apple gains ground with each step in software and hardware towards health and fitness. garmin seems losing its ground more and more. i don't like the look of the apple watch and prefer android to ios but i have to admit: the abilites from the apple watch with respect to health and fitness is ahead my fenix 5s plus

    I do not believe this is the case. The Apple watch is designed for the mass consumer, does not support ANT+ devices and has no Firstbest analysis capabilities. It cannot even estimate VO2 max or track sleep (as most people charge it whilst they sleep). Depending on the Garmin watch you buy I believe they are focused on different sports and tasks and provide more "health and fitness" capabilities than most on the market today.
