GPS/GNSS Calibration Services from CTPM


Accurate positioning has become essential infrastructure for modern construction, surveying, marine navigation, oil and gas operations, and automotive testing. Commercial GPS and GNSS systems must deliver precise, verifiable positional accuracy to support project layout, quality control, and regulatory documentation across increasingly demanding applications. When GPS/GNSS equipment falls out of calibration, the consequences can include inaccurate positioning data, costly rework, project delays, and compliance failures in industries where precision directly affects safety and project outcomes.

Cal Tec Process Management, backed by the trusted Accredited Labs network, provides ISO/IEC 17025 accredited GPS/GNSS calibration services that deliver the traceable positional accuracy your operations require.

What is GPS/GNSS Calibration?


GPS/GNSS calibration is the process of verifying and documenting the positional accuracy of commercial GPS and GNSS systems against known reference positions and traceable standards. This service produces detailed positional accuracy data reported in SI units with NIST traceability, providing the documentation needed to meet the quality standards of heavy civil construction, marine, oil and gas, and nuclear plant construction industries.

Calibration covers complete RTK (Real-Time Kinematic) system components, including the base station, rover, data collector, and radios, ensuring that every element of the positioning system contributes to accurate, reliable results. For automotive testing and proving ground applications, precise speed and distance calibrations are also available, along with GPS Time Standard calibration.

Why GPS/GNSS Calibration is Essential for Your Operations


Project Accuracy and Quality Control
Construction layout, grading, and surveying all depend on accurate positioning data. Calibrated GPS/GNSS systems ensure that positional measurements translate into accurate fieldwork, reducing costly rework and layout errors on job sites.

Regulatory Compliance and Industry Standards
Heavy civil, marine, oil and gas, and nuclear construction industries increasingly require documented, traceable positioning accuracy as part of quality management systems. ISO/IEC 17025 accredited calibration with NIST-traceable, SI-unit data provides the documentation these industries demand.

Complete System Verification
Because positioning accuracy depends on every component of an RTK system working together, calibrating the base, rover, data collector, and radios as a complete system provides more meaningful assurance than testing components in isolation.

Automotive Testing and Proving Ground Precision
Speed and distance measurements used in vehicle testing and proving ground applications require precise, calibrated GPS data to ensure valid test results and repeatable performance benchmarking.
