Abstract: A system includes a base station that includes an RTK base unit and a static RTK rover unit, the RTK base unit and the static RTK rover unit being at a same fixed location; a GPS antenna corresponding to the base station and being at a first position; and a management center in communication with the base station. The RTK base unit includes a first GPS receiver coupled to the GPS antenna, the static RTK rover unit includes a second GPS receiver coupled to the GPS antenna, the static RTK rover unit is configured to determine its position as a second position according to GPS information received via the GPS antenna and RTK correction information received from the RTK base unit, and the management center is configured to determine whether the RTK correction information is valid.

Abstract: A signal aspect enforcement method for a rail vehicle includes determining, by an on-board controller on the rail vehicle, a position of the rail vehicle; determining, by the on-board controller, whether a first signal aspect for a signal matches a second signal aspect for the signal; and determining, by the on-board controller, at least one of a route of the rail vehicle or a speed limit of the rail vehicle when the first signal aspect matches the second signal aspect. The first signal aspect is determined from first data from first system on the rail vehicle, and the second signal aspect is determined from second data from a second system on the rail vehicle, which system is different from the first system used to determine the first signal aspect.
