Abstract: PURPOSE: A location positioning system and a method are provided to guarantee location positioning stability and reliability while improving location positioning precision, by using a dual mode and thereby changing the positioning mode according to the environment. CONSTITUTION: A location positioning system includes a phase positioning part(321), a code positioning part(322), and a positioning engine(323). Each of the phase positioning part and code positioning part include a monitoring part and a determination part. If the number of GNSS(Global Navigation Satellite System) satellites is at least four and there is no cycle slip, the phase positioning part performs location positioning by using carrier phases. If the number of GNSS satellites is less than four or there is a cycle slip, the code positioning part performs location positioning by using a code. The positioning engine includes an integer ambiguity calculation part and a vision system, and calculates integer ambiguity based on received location information data after the location positioning of the code positioning part.
