Abstract
A precise positioning method and system is disclosed wherein at least one ground transmitter is used for transmitting a ranging signal with code modulation. The at least one ground transmitter is configured to receive a signal from at least one satellite and a second ground transmitter. The at least one ground transmitter measures a code phase of the received signals. The measured code phase information is communicated to a rover that is associated with a user. The rover can determine the user's precise position based on the measured code and/or carrier phase information and a clock correction model.
