Altitude wrong

6957586 over 4 years ago

I am a helicopter pilot and fly at different altitudes.

Since 10 days my FR945 seems to miss my landings. The altitude goes up (roughly correct) but not down again.

Anyone experiencing the same?

Hi, there were likely some related changes in 6.20. In my case after update watch barometer auto mode doesn't work like before. While driving to slightly elevated place (say 250->700m) watch doesn't recognize…

Something is going on. I don't know if you use meters or feet for elevation, but there shouldn't be an instantaneous change from -541 to 93 on your elevation graph either way and the same with the barometer…

At a certain point of the uphill journey it also changes by 20 millibars and then remains stable, but so on arrival I find myself with an incorrect altitude (and pressure)

I'm not sure I'm following you and I need more information. If you travel uphill the barometer should drop. Is the barometer only changing for part of the ascend? When you arrive, how is the elevation and pressure incorrect? Is the elevation to high or low? Is the pressure increasing?

Altitude measurement during activities is just fine for me. The only thing I can see is v6.2 not detecting elevation change outside of activities described earlier in this thread. I'd guess something changed around barometer "watch mode auto", like less frequent sampling when there is no activity. Might not be necessarily timed activity as per my last observation (like steps above x being enough to have watch doing more frequent sampling). Speculation - battery saving measure.
