1. A system for disseminating GNSS corrections information comprising:
a GNSS receiver coupled to a GNSS antenna wherein the GNSS antenna receives observations from a plurality of in-view satellites;
a positioning engine operating on a computing system collocated with the GNSS antenna; and
a corrections generator operating on a computing system remote from the GNSS antenna,
wherein the corrections generator is configured to transmit antenna phase center corrections to the positioning engine,
wherein the positioning engine is configured to determine a set of corrected satellite observations based on the antenna phase center corrections and determine a high accuracy position of the GNSS antenna based on the set of corrected satellite observations,
wherein the antenna phase center corrections are rebroadcast to the positioning engine with a time period less than an update time period for changing the antenna phase center corrections.
