Frequently Asked Questions
What should a GPS calibration checklist include?
A GPS calibration checklist should cover: comparison of position output against known survey control points with documented residuals; horizontal and vertical accuracy verification against applicable standard (e.g., FGDC Part 2/3 or project specifications); PDOP (Position Dilution of Precision) monitoring and acceptance threshold documentation; satellite constellation quality and minimum satellite count verification; multipath assessment at intended deployment locations; antenna calibration certificate currency; baseline solution quality indicators (fixed vs. float ambiguity resolution for RTK systems); equipment firmware version and update log; and calibration record traceability to NOAA NGS control monuments or equivalent national standard.
How often should GPS calibration be conducted?
Survey-grade GPS receivers should be checked against established control benchmarks at the start of each project and after any equipment servicing, firmware update, or physical damage. FMCSA ELD GPS components are verified through the device certification process - operators must ensure they use certified devices per 49 CFR 395 Appendix A. Aviation GPS avionics must be maintained per the manufacturer's CMM, with inspection intervals specified in the aircraft's maintenance program. ISO/IEC 17025 accreditation requires calibration intervals to be set based on stability data, typically annually for survey GPS instruments.
What regulations govern GPS calibration?
GPS calibration standards vary by application: FGDC Geospatial Positioning Accuracy Standards (Parts 2 and 3) govern survey GPS accuracy requirements for federal land records. FMCSA 49 CFR Part 395 and Appendix A govern ELD GPS position accuracy for HOS compliance. FAA AC 20-138D governs GPS avionics certification and maintenance. ISO/IEC 17025:2017 governs calibration laboratories providing GPS calibration services. NOAA NGS provides the national geodetic reference framework used to verify GPS accuracy, including the National Spatial Reference System (NSRS).
Who is qualified to perform GPS calibration?
Survey GPS calibration should be conducted by a licensed Professional Land Surveyor (PLS) or a GPS instrument technician trained and authorized by the manufacturer. For aviation avionics, calibration must be performed by an FAA-certificated Avionics Technician (A&P or Avionics rating) per 14 CFR Part 65. ELD GPS verification is a device-certification process handled by manufacturers, not field calibration. For ISO 17025 accredited calibration services, the laboratory's qualified technical staff perform GPS receiver calibrations under accredited scope.
What are the consequences of using uncalibrated GPS equipment?
Use of uncalibrated GPS in land survey applications can result in boundary dispute liability, incorrect as-built documentation, and rejection of survey plats by recording authorities. FMCSA ELD GPS errors that result in inaccurate HOS records create log falsification violations under 49 CFR 395, with civil penalties up to $15,846 per violation (49 CFR 386 App. B, 2025). Aviation GPS errors in approach procedures can cause controlled flight into terrain (CFIT) accidents. In legal proceedings, position data from uncalibrated GPS instruments may be rejected as evidence. ISO 17025 laboratory accreditation can be suspended for use of out-of-calibration measurement equipment.
