Or my form is linked to GNSS quality on that particular day
Clearly you, in particular, need to watch out for those times when Galileo is in conjunction with Beidou while GPS is in retrograde. Have your geo-location read. It’s a side biz for the nerdier astrologers.
-
@Fenr1r will have to keep that in mind, good point. Right after I check my tarot before my next run that is!
-
@Łukasz-Szmigiel without wanting to mitigate an issue an advice I give to all my running friends:
Do your self a favor and buy a stryd. Suunto, Garmin, COROS , that will help you with the pace no matter what brand name you are using.
-
@Dimitrios-Kanellopoulos hehe, that’s funny as recently I was considering buying a Styd for my runs, just to rule out occasional distance problems due bad GPS signal.

Best advice ever and deep a bit into the knowledge of running with power. If you run into a tunnel you will get instapace… Stryd is very reliable.

@Dimitrios-Kanellopoulos I run for fun, good health and mood (and mud too, when weather permits, if you know what I mean). The pace is not an issue for me nor does it distract me in any way. Especially now when I’m still struggling with marathon-related injuries and I have no need for speed.
Just curious if there’s any significant relationship between what watch gets from GNSS and the pace it computes. That’s it
Stryd is interesting (numbers, numbers, hehe) but I’d rather get a new pair of shoes when the need arises (or a new backpack, etc.). I find it quite pricey for what it does for 100% amateur use.

@Łukasz-Szmigiel roger
-
@Dimitrios-Kanellopoulos the gain in autonomy (duration) is known? it concerns other systems but not GPS?
the gain is not canceled by more frequent points registration? -
There are 2 things for you to consider.
- Sampling rate aka how often you ask for GNSS updates (your location)
- Recording rate aka how often you record those GNSS points.
The recording rate changed, the sampling rate was always 1s
-
@Dimitrios-Kanellopoulos OK. the recording frequency rate does not affect the autonomy.
“the sampling rate was always 1s”: it makes sense but then how do you gain autonomy ? (simple curiosity
)or is the improvement more about precision?
or both? -
Best: 1s Sampling rate
Endurance: 1 minute sampling rate
Ultra: 5 minute sampling rate -
@Dimitrios-Kanellopoulos I know.
I was talking about the gain announced a few comments above? (New GPS firmware from sony that improves many things including power consumption for other GNSS systems than GPS) -
@Rob33 I suppose the maths that the chip does are simplified and other techniques. Complicated subject. Includes SNR etc.
-
@Dimitrios-Kanellopoulos you mentioned that new GPS firmware improves power consumption with other GNSS than GPS. Shouldn’t it be reflected in estimation on activity start screen? Or simply those gains in power are reflected in better accuracy? Or are they internal and not reported by battery time estimation?
Having my watch at 85% I get 20h estimated time with GPS only and GPS plus Beidou and 14h with GLONASS and Galileo which is identical as with previous firmware.
-
@Łukasz-Szmigiel true, I just tried the same, full battery 24h best performance on GPS only, 18h best performance GPS +Galileo
-
@Łukasz-Szmigiel @markytarky When I test the battery life, I typically do this on a run or ski that is at least 4-6h, longer if I can. The watch will provide an estimate but it is just an estimate. Moreover, if you are needing sufficient battery for long endurance events does it really matter which satellite system is used? Or how precise your track is? Under long events Endurance mode will only get a GPS fix every minute and FusedTrack will fill in the details so why not use GPS only? There are improvements with power consumption but what you are asking simply does not make that much sense.
-
@Brad_Olwin The idea is, I believe, to be able to do ultra trail (up to 24 -26 hours) while still using the Best 1s mode
-
@Brad_Olwin thanks, I got your point. I think we both were referring to this sentence: New GPS firmware from sony that improves many things including power consumption for other GNSS systems than GPS. So kind of common sense is telling us most probably it will increase the estimate while using the GPS with another system. Thank you again.
-
We didn’t bump up those numbers as the improvement might be 1-2h (or more).
Changing the estimates can create complexity , from people who read the specs but still don’t have the update etc.
Better be on the safe side.
-
the best autonomy remains in GPS alone?
