gpstest VS tailscale

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.

Tailscale - Built on WireGuard. Easy to use. Control server is closed source. Client code available with a BSD3 license + separate patents file.

Tailscale

I'm using the GitHub version of tailscaled on one of my Macs as a background daemon launched at boot. To upgrade to the latest version, try the following:

Tailscale is a VPN service that makes the devices and applications you own accessible anywhere in the world, securely and effortlessly. It enables encrypted point-to-point connections using the open source WireGuard® protocol, which means only devices on your private network can communicate with each other.

Might be possible to do using a VPN as long as you can get broadcast/multicast packets forwarded.

Tailscale unfortunately doesn't support it...yet?

Tailscale - Make depaware output patch compatible

Tailscale is another way of doing it. I'm using it to access my Pi's Samba shares from my phone but it works from Windows as well.
