Abstract
An apparatus provides independent precise positioning for a reference station including a GNSS antenna and a GNSS receiver. The GNSS receiver generates GNSS data based on a plurality of GNSS signals received at the GNSS antenna, including GNSS signals having augmentation information. The apparatus includes a positioning processor, a signal processor, and a signal transmitter. The positioning processor calculates a current position of the reference station based on GNSS observation data and GNSS augmentation data obtained from the augmentation information included in the received GNSS signals, without using position information of another reference station, whereby the reference station is independently installed at a desirable location without surveying or measuring the desirable location. The signal processor generates error correction information including the current position of the reference station in a predetermined data format such as RTCM or CMR, based on the GNSS augmentation data.
