Calibration and registration before use are required for electronic positioning equipment because these devices directly affect the accuracy and traceability of survey results. GNSS receivers and smart stations rely on precise timing, firmware, antenna characteristics, and external correction data. Calibrating them corrects biases such as antenna phase center variations and receiver time drifts, ensuring reliable position solutions. Registration creates a traceable record of the equipment with the regulating authority, including ownership, calibration certificates, and maintenance history, so surveys can be audited and comply with standards. Traditional mechanical-optical tools like tapes, compasses, alidades, prisms, levels, and transits are maintained and checked through standard procedures, but the regulation specifically targets calibration and registration for GNSS devices to safeguard positional integrity and accountability.
