The main idea is that surveying tools must be validated against official measurement standards before they are used. In this regulation, the proper authority to calibrate and register conventional survey instruments, GNSS receivers, and smart stations is the Land Management Bureau and its Land Measurement Standards unit. They are the bodies charged with land surveying oversight, maintaining the official measurement standards, and keeping the instrument registration so that surveys meet the required accuracy and legal traceability.

NAMRIA is the national mapping authority, and while it plays a crucial role in geospatial data and standards, the regulation assigns instrument calibration and registration to the LMB/LMS. DENR is the parent department, and LGUs manage local administration, but neither is the designated body for calibrating and registering surveying instruments under this rule. Ensuring calibration and registration with LMB/LMS guarantees that all surveys conducted under the regulation rely on validated equipment and documented accountability.
