Abstract
A locally enhanced GNSS wide-area augmentation system is provided. The system includes a global reference processing center and a wide-area reference network formed of wide-area reference stations and GNSS satellites. The global reference processing center is in communication with the wide-area reference network in order to receive global network data and form global correction data. The system also includes a local reference processing center and a local reference network having reference stations and a rover receiver that communicate with GNSS satellites. The local reference processing center is in communication with the local reference network in order to receive local network data and form local enhancement data.
