Hi, I would like to buy F9P-based board to use it as GNSS-receiver in my car. I have a couple questions:
1) What is expected accuracy (vertical and lateral) in standalone mode with a cheap antenna at open field?
2) Can you explain in details what kind of 3G module do I need to receive SSR/RTK corrections in order to get +/-3 centimeter precision and how to connect it to your board? Will it work everywhere in Europe? As far as I understand, it will receive corrections from mobile operators cellular network stations.
1) WIth a multiband antenna you will achieve around 1-2 meters accuracy. With a cheap classic 5$ GPS antenna you will get the same as with other GPS, around 2-3 meters.
2) You need to connect to an online correction service like in this example: https://www.ardusimple.com/simplertk2b-performance-in-standalone-mode-and-ntrip-corrections/ Currently there are national services, european service are mostly at a fee.
