I belive they were enhancing it with terrestrial base stations (Loran-C was mentioned in the discussion, which was 10+ years ago). John Deere has proprietary secret sauce and if I recall correctly, they can get sub 1" accuracy.

Some states, such as Iowa, run a network of these stations and provide free access to the public [1]. 0 - https://www.sparkfun.com/products/15136 https://www.sparkfun.com/products/15136 1 - https://iowadot.gov/rtn/IaRTN-resources/About-the-IaRTN https://iowadot.gov/rtn/IaRTN-resources/About-the-IaRTN
