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.
