tl;dr: arm swing is noise compared to accuracy of GPS
Is there a GPS watch that somehow accounts for this to produce more accurate data?
No, there is not.
The reason is among others that to get that level of accuracy for GPS requires significantly more than the GPS locator can provide.
The U.S. government is committed to providing GPS to the civilian ...
I just came across a great hybrid (depending on the exact use case): The Automatic Pro plugs into a vehicle's OBD-II port, transmits location updates every 20 seconds when the vehicle is in motion, and draws its power from the car.
Yes, it's an "active" tracker, but the $130 purchase price includes "at least" 5 years of 3G data service.
So it's not exactly ...
You can achieve this using an SDR (software-defined radio). It's essentially a device that can be programmed to transmit any radio signal you want:
These SDR boards are known to be able to produce GPS signals:
bladeRF (pictured above)
(To configure one of those to send out GPS signals, you could use for example gps-sdr-sim, an open source ...
The Globalsat ND100 seems to be what you're looking for.
It's a bit bulky, but it seems to do everything you need it to do.
It's only $35USD
Has a thumb-drive-like form factor (Besides it being a bit bulkier than a thumb-drive)
It states to have "Very low power consumption"
According to this article, any GPS receiver that advertises NMEA-0183 compliance ...
I don't know if there are any devices that can be charged while in the pouring rain or wet at all for that matter. But if you just need GPS signal while biking then I suggest looking at the Xperia XZ compact line up. My wife and I have had Xperia phones and they do great even with full water submersion. Just turn on glove mode and they won't interact with ...

Make your own using Raspberry Pi with GSM module, battery and additional software to track it. This is the hard way.
"Car" trackers can be actually used for other purposes. This $199 device looks good
but there's also a way cheaper alternatives that costs only $24.95
3. Two Phones method. Basically all you need to do is just to turn on GPS on the ...
I have personally used an Arduino with a GPS module an SD Card module to plot GPS coordinates. This is a bit of a DIY project and requires some programming, but given your StackOverflow reputation this should not be an issue for you at all and has the added benefit of being customisable to your exact needs.
The Arduino can be powered using a powerbank which, ...
Your existing cell phone
save to phone/sd card
extra USB battery packs to keep cell phone charged.
Cell phones use different GPS chipsets, therefore I can't say you will get reception or how good it will be. Your cellphone's GPS may or may not be accurate and enough for you. Also get an app that logs in the background so screen can be off.
$14.95 will get you this:
It has a plug & play Grove connector, so you can easily add on GPS for a further $12.
If you can live without GPS, or can solder, then I also recommend LilyGo.
They have a slim wristband, like an activity tracker for about $20:
and a wristwatch with a larger screen for about $25:
All three of these are ESP32 based, so have ...
I have years of experience with GSM GPS trackers.
I work at daily basis with GPS trackers and reception servers.
There are few things that affect the devices you would need.
So place let me know answers to these few questions.
First you should decide what kind of protocol you would like to have ?
Most basic GPS trackers support TCP and UDP, but there is ...
Just came across another option: TrackR are little sub-$30 transponders with a one-year battery life, though apparently they depend on a device running their app to come within 100 feet of the transponder to update its location.
