Altitude incorrect while hiking

[Łukasz Szmigiel]

@Egika what about sudden pressure drop due to storm happening i.e. 1+ hours after the start of activity? Won’t FusedAlti try to correct it after the initial calibration?

@Łukasz-Szmigiel fusedalti works during the whole activity.

[Sergei Ladeishchikov]

@isazi what can block the work of FusedAlti? or could it be a glitch? Does it make sense in such a case to send logs to check the work of FusedAlti?

[isazi]

@Sergei-Ladeishchikov not sure, maybe related to you using good and then switching to best GPS mode. Logs make sense if you can send them after the activity, it may be too late now.

[Sergei Ladeishchikov]

@isazi well, when i go camping, i will deliberately not calibrate the height myself, let the alti work.

[isazi]

@Sergei-Ladeishchikov I never use manual calibration, and my Vertical is usually very precise, or at most 5-6 meters different from the “real” altitude.

@Sergei-Ladeishchikov
Do you have an Android phone?
If yes, you may have a look at the raw data file of this activity and check GPS altitude registered vs fusedalti corrected one.
If yes, I will search for posts which explains how to do (too old now )

[Sergei Ladeishchikov]

@Mff73 that’s interesting, never heard of it! Yes, I have an android. What should I do for analysis?

[Egika]

@Sergei-Ladeishchikov you can download the json file of the activity and check for “FusedAlti” string etc.

@Sergei-Ladeishchikov
As Egika said,
Search for this kind of files
/storage/emulated/0/Android/data/com.stt.android.suunto/files/smlzip/entry__.zip
There are two json files in this zip, samples is containing your activity data with lots more information than displayed in SA

@Mff73 Thank you, I have already reached this point). Thanks to Egika, I saw that FusedAltiUsed:true. Also, about halfway through the hike, I saw that the Altitude and GPSaltitude were very different, 3265m and 3349m respectively. I am in touch with Egika.

@Sergei-Ladeishchikov hello, what was the conclusion here? have you figured out what was the problem?

Thank you.

Hola. Mi Vertical muestra la altitud con una gran precisión.
Sin embargo, cuando realizo una actividad, tanto los metros de ascenso como los de descenso, me muestran el doble aproximadamente.
Es decir, siguiendo una ruta que se tiene 800 m de desnivel total, el vertical me dice que he hecho 1600.

A alguien le ha sucedido esto?
