Abstract
In one embodiment, a method comprising, receiving at a moving vehicle first global navigation satellite systems (GNSS) information broadcasted from a base station and second GNSS information provided by one or more satellites; determining by a processor residing in the vehicle a position of the vehicle based on the first and second GNSS information; and re-broadcasting the first GNSS information to a receiver located remotely from the moving vehicle.
Claims15
A system, comprising:
- a base station comprising a global navigation satellite systems (GNSS) receiver and transmitter circuitry, the transmitter circuitry configured to wirelessly transmit first GNSS information;
- a first vehicle comprising a GNSS receiver, and receiver circuitry and transmitter circuitry configured to receive and wirelessly transmit, respectively, the first GNSS information, and further configured to transmit an indicator of reliability including a number of times the first GNSS information has been repeated;
- and
- a second vehicle comprising a GNSS receiver, and receiver circuitry configured to receive the first GNSS information and the indicator of reliability from the first vehicle, the receiver circuitry configured to select the first GNSS information only if the number of times the first GNSS information has been repeated is below a predetermined threshold,
- wherein the GNSS receivers of the base station, the first vehicle, and the second vehicle are each configured to receive second GNSS information from a satellite network,
- wherein the first vehicle and the second vehicle each comprises a respective processor configured to process the second GNSS information based on the first GNSS information and use the processed second GNSS information to determine a respective position of the first and second vehicle,
- wherein the first vehicle and the second vehicle each comprises an auto steering mechanism that operates according to the processed second GNSS information.

A system, comprising:
- a base station comprising a global navigation satellite systems (GNSS) receiver, and a transmitter configured to broadcast real time kinematics (RTK) correction information according to a first communications range;
- a first vehicle located within the first communications range and within a range of validity of the RTK correction information, the first vehicle comprising a GNSS receiver and transmitter and receiver circuitry, the receiver circuitry configured to receive the RTK correction information from the base station, the transmitter circuitry configured to rebroadcast the RTK correction information according to a second communications range that partially overlaps the first communications range, the transmitter circuitry further configured to transmit an indicator of reliability including a number of times the first GNSS information has been repeated;
- and
- a second vehicle located outside of the first communications range and within the second communications range and within the range of validity, the second vehicle comprising a processor, a GNSS receiver configured to receive satellite signals, and receiver circuitry, the receiver circuitry configured to receive the RTK correction information and the indicator of reliability from the transmitter circuitry of the first vehicle, the processor configured to determine a position of the second vehicle based on the satellite signals and the RTK correction information only if the number of times the first GNSS information has been repeated is below a predetermined threshold,
- wherein the second vehicle further comprises a navigational guidance system that autonomously guides movement of the second vehicle based on the determined position.
