Hello,

I am looking to identify what device(s) to procure for the following application:

Looking for NTRIP based RTK solutions which can give us \<3cm accuracy. We would like to place this device on a ground and aerial robot. We would also like to be able to fetch the data from a linux machine.

Thank you

Our RTK products achieve ~1.4cm accuracy [https://www.sparkfun.com/search/results?term=rtk](https://www.sparkfun.com/search/results?term=rtk)

Something like [https://www.sparkfun.com/products/19984](https://www.sparkfun.com/products/19984) for the base and this [https://www.sparkfun.com/products/22693](https://www.sparkfun.com/products/22693) for the bot

We also just started selling this [https://www.sparkfun.com/products/23088](https://www.sparkfun.com/products/23088) which is even more accurate!

Hi, Thank you for your response. Any product I can use without a base station? Perhaps I get corrections from NTRIP?

Also, how far can the base station be for the above recommended configuration?
