gpstest VS open-location-code

If you really want to see all the gps-like services out there and have android, you must play with the open-source GPStest

https://github.com/barbeau/gpstest

I've been fascinated for years how badly GPS does altitude (mean-sea-level)

in the USA they had to build an augmentation system for airplanes for altitude (WAAS)

Use https://github.com/barbeau/gpstest (Android only). It give the most real time data on GPS and accuracy.

GPSTest (version 3.10.0): An app for testing GPS and GNSS capabilities of a device

I'm the developer of the GPSTest app, and I built a crowd-sourced database of device GPS/GNSS capabilities.

It is possible on quite a few modern Android phones to access raw receiver data and do post-processing using a rinet file to get mm-level accuracy. It's a little over my head since this isn't my industry. One of Google's more obscure Android apps to be used with it: https://play.google.com/store/apps/details?id=com.google.and...

GPSTest also carries some logging functionality to do the same: https://github.com/barbeau/gpstest

If you did not install GApps try outdoor with an unobstructed view of the sky for 10 minutes to get the first fix with apps like GPSTest by barbeau or SatStat for example.

I hope more people can contribute with GPSTest app.

For a visual of what speed accuracy figures one might expect, I suggest trying GPSTest (not to be confused with similarly named apps). It'll display accuracy values along with many other values.

If you install this app, you'll see exactly what GPS data your phone is picking up.

I can see GPS, Galileo, Chinese, Russian, and Japanese ones.

Pluscode is a trademark. The actual standard is called "open location code" and is unrestricted - https://github.com/google/open-location-code/

Yeah, that seems like a bad design choice. If you look at the spec [0], you can see that they only use "23456789CFGHJMPQRVWX" in the codes. They apparently scored the letters based on how well they can spell 10000 words in 30 languages, without thinking about character similarity. If they had involved actual humans instead of counting letter frequency, they might have noticed that the letter W looks similar to VV, and that its English name is "double U". And tried a letter like N or Y, which would be much harder to confuse.

Lots of thoughts from the founders incl comparison with other systems here: https://github.com/google/open-location-code/wiki/Evaluation-of-Location-Encoding-Systems

I wish https://plus.codes/ took off. The benefit compared to what 3 words is that you can use the closest city to give directions and cells next to each other share the bigger cell name.

And an additional shoutout for https://plus.codes/ from Google.

New to this so sorry if this is stupid. I've been trying to use https://plus.codes to try to check an address for availability at starlink. Whatever code I put in, it simply tells me afterwards "please enter an address or a plus code". That website seems to give me either a shorter or a longer plus code. Neither of them seems to make the starlink website happy. When I try putting in the address, it doesn't like that either. Confused on where to go from here.
