All Geodetic Control Surveys shall be conducted in which reference system?

The Philippine Reference System 1992 is the official national frame for geodetic control surveys. It provides a single, uniform coordinate system across the country, ensuring that data from different surveys and agencies line up correctly. PRS92 is designed to work with GPS measurements and is tied to the WGS84 framework, but it is defined specifically for the Philippines to support precise and consistent control networks. This makes it the current standard, superseding older local datums like Luzon Datum 1911. The Philippine Geoid Model, while important for converting between ellipsoidal and orthometric heights, is a separate component and does not define the horizontal reference system.
