I just learned that Switzerland has a nationwide RTK network for cm level positional accuracy using GPS, Galileo, GALILEO, and/or Beidou, GNSS systems. And they have a nice map of all the station locations[0].

It's a bit of shame that the pricing seems to be rather steep for frivolous use, but it seems to be rather new.

It would be interesting to see what possibilities a totally free nationwide RTK system would open up.

Swisstopo is a government organization that already provides many services like highly accurate maps for free.

In Portugal there are 2 already, one free and one paid. The free one was implemented almost 20 years ago.

It amazes me that a country like Switzlerland only now implemented such a service, and quite expensive, nonetheless.

Finland has a free nationwide RTK network. It’s nominally only for testing and R&D use, tho, and you have to renew your account every three months.

However, you can easily setup your own RTK base station for a few hundred bucks. Very convenient to use the free service to determine the static coordinates of your base station.

The pricing norms for RTK correction networks were set 20 years ago, when operating your own base station meant buying a second $20,000 dual frequency receiver, and taking an extra guy any time you go out to do a survey, whose job is just to guard the base station.

This made a $2000 a year network correction service seem like great value for money!

Some networks offer more affordable options these days - such as weekly and hourly licenses for drone pilots.

Many US states also have their own (free) CORS networks, primarily from transportation departments. NOAA helps keep track of them all. Not many of these are realtime unfortunately.

Luxembourg's RTK system is completely free to use: https://act.public.lu/fr/gps-reseaux/spslux1.html

Real-Time Kinematic - Differential GNSS updates broadcasted by radio or other means that aid accuracy while moving. It was a Trimble (GPS) marketing term around 2000 just prior to SA that was able to defeat it and offer 10mm horizontal error and 1m vertical error.

Disclaimer: I worked on firmware on RTK radio gear.

This should be another crowdsourced sensor fabric network, like air quality sensors, AIS, ADS-B, distributed SDR, etc.
