測位差を利用した精密位置補正装置およびその方法

Japanese Patent JP6976640

B2

According to an embodiment, an apparatus for precise position correction using a positioning difference comprises a first distribution information obtaining unit gathering first distribution information from an external terminal, a global navigation satellite system (GNSS) receiver obtaining a GNSS positioning value of the apparatus based on a GNSS, and a positioning correcting unit obtain a corrected location of the apparatus by correcting the GNSS positioning value using the gathered first distribution information. The first distribution information includes a GNSS positioning value of the external terminal, a GNSS positioning time, a precise positioning value, and a positioning difference between the GNSS positioning value and the precise positioning value.
