Abstract: A method for disseminating corrections can include receiving a set of satellite observations at a GNSS receiver; transmitting the corrections to the GNSS receiver, wherein the corrections; and determining a position of the GNSS receiver, wherein the set of satellite observations are corrected using the corrections. A system for disseminating corrections can include a positioning engine operating on a computing system collocated with a GNSS antenna; and a corrections generator operating on a computing system remote from the GNSS antenna, wherein the corrections generator is configured to transmit corrections to the positioning engine, wherein the positioning engine is configured to determine a high accuracy position of the GNSS antenna using the corrections, wherein the corrections are rebroadcast to the positioning engine with a time period less than an update time period for changing the corrections.
