Abstract
A time-differenced carrier phase (TDCP) measurement value-based navigation system according to one embodiment of the present disclosure comprises: a satellite navigation system information reception unit for acquiring satellite navigation system information including a carrier phase measurement value; an initial position determination unit for determining an initial position of a target on the basis of the satellite navigation system information; a TDCP acquisition unit for acquiring a TDCP measurement value; a relative position determination unit for determining a relative position of the target on the basis of the TDCP measurement value; and an absolute position determination unit for determining an absolute position of the target by accumulating relative positions according to time of the initial position of the target. Therefore, time and expenses required for determining integer ambiguity can be reduced, and precise position of a cm-level error can be measured by using a low-cost satellite navigation system information receiver.
