It would be interesting to find out the distance on a professional, flat track, running straight in center for a few rounds to see which device is more accurateRandM, such difference is ok. I am surprised by negative elevation. Is Houston below sea level?
As you can see on the map (i assume it Casio) it shows short cut through some house. That usually how it happen. It calculates within blank list of data without link to actual map or actual world and these deviations from actual route are these errors.
On Timex i had some issues when it kinda loosing it and stops calculation (no signal lost) and later catches on. I mean running something like 320m on 400 circuit is extreme example of this behavior.
so it jumps to next point it find itself in and calculates distance as if you really jumped from last to current by short cut.
Another issue is if watch goes into automatic exercise pause and it takes some time to regain it's position so you see these "short cuts".
In my case it was Garmin Forerunner110. I already did it. Neighborhood in the Iphone vs Casio vs apple watch should be as flat as track for testing purposes...It would be interesting to find out the distance on a professional, flat track, running straight in center for a few rounds to see which device is more accurate
probably cos your phone uses cell towers as well for greater accuracy
AS WELL. as per spiels from phone manufacturers and app developers, they use the cell towers in conjunction with gps for greater accuracy.Cell towers are less precise than GPS by huge margin. like 700 time difference for civil applications and for actual it's 3500 time the difference.
Not sure if all are used at the same time, or whether watches manufactured for different regions use different satellite systems.In addition to GPS, the watch acquires data from GLONASS and Michibiki (QZSS) satellite systems.
Most of navigation modules can use at lest 2 but many 3 systems. It's not like system is different it's key to decipher signal and frequency.Just reading on the official G-Shock page (https://world.g-shock.com/asia-mea/en/products/g-squad/gbd-h1000/) that

Thanks for the detailed comment. Yeah, with my Garmin Instinct, I was able to select which to use. I believe the options were (1) GPS, (2) GPS+GLONASS, (3) Galileo. Like you said, I'd be curious if the GBD-H1000 uses all of them at once, 1 of the 3, or a combination of them.Most of navigation modules can use at lest 2 but many 3 systems. It's not like system is different it's key to decipher signal and frequency.
Here you can see how using both technologies (not sure about 3) can yield better results in urban setting (compared to 1).
Most phones use GPS/GLONASS and can clearly use both at same time in order to compensate for obscured satellites and gain almost immediate lock.
Same can be said about smartwatch like my Samsung. Immediate lock outside and pretty consistent navigation.
I am intentionally not talking about 3d system. Apart from Australian based Tetsu it's rather useless for most of us.
I did not mention Casio because i am not sure how Casio arranged it and whatever it using. Long satellite locking times are usually typical for single (GPS/Glonass/china/Europe Galileo) use.
Don't take it as statement. Apart from Casio designers nobody knows it for sure. So i am not saying what exactly going on just pointing toward how it works in general.
Updates are rising....I've been holding off on a fitness watch for years already after owning a Fitbit once that didn't even last a year. I vowed not to get another until G-Shock put one out that I could trust would last.
Now that it's finally a thing I'm disappointed that it's only a running watch - I bike, I hike... I don't run. From what I've read so far it's not really at it's full potential when recording activities other than running.
However, I've read some reviews of the GBD-H1000 that mention upgrades/improvements to the software and I'm curious if there's any solid info about this. Is it a sure thing? Is there a timeline for these improvements?
People who had ever enjoyed smartwatches and fitness trackers look will look at it with pity. Any top 3 out 4 manufacturers and #5 (Apple, Samsung, fitbit, amazfit while Garmin is #5) come with updates and improvements.Personally, I doubt that Casio will add extra features that go beyond running on this particular model. Likely, they will come up with a new model in a couple of years that can do that. I mean, there's a reason why they labeled the button as "RUN" button on the watch. G-Shocks have always been relatively specialized (Rangeman for hiking; Frogman for diving, etc.). I predict that there will either be a more multi-functional fitness watch or a dedicated biking watch. I don't see them making a hiking watch because that's kind of what the Rangeman is already for.
Most, if not all running GPS watches are made for triathlons as well. They usually have at the minimum biking and swimming tracking unless you are talking about the most basic models.It's different target audiences. As someone who owned an Apple Watch (2018, returned) and a Garmin Instinct (earlier this year, returned), I got interested in the GBD-H1000 because it is a watch with some running and fitness features (whereas the others are fitness watches with some watch features). I can't stand the battery life of Apple or wearOS watches; I don't want yet another device where I have to constantly check the battery and bring yet another charger on trips. If they ever make a watch that I can wear everyday without worrying about battery, I may revisit.
I agree though that it would be nice to add these features, and it may increase the target audience for this particular watch. But interface-wise, it's already crammed. It would require a revamp, and it would probably make runners, who bought the watch for this exact reason, upset.
Not non smart GPS watches. These often are runners and that's it. You can track your time and distance but by any means there is 0 adjustments for different sports. Garmin (i am citing use Forerunner 110) went for better flexibility within their web service. So you do can choose activity but nothing on the watch itself.Most, if not all running GPS watches are made for triathlons as well.
