Transmitter Placement & Initialization

Calibration begins by strategically placing iGPS laser transmitters around the measurement volume. Their positions must be stable and provide overlapping coverage of the workspace.

Reference Sensor Setup

A reference sensor or calibrated object (such as a known artifact or fixture) is used to establish a baseline. This helps define the coordinate system and ensures consistency across the network

System Self-Calibration

iGPS systems often support self-calibration with monuments, where the system uses known distances and angles between transmitters and sensors to automatically refine their positions and orientations. This step ensures that all transmitters are correctly aligned within a unified coordinate frame.

Sensor Validation

Sensors (e.g., on an iProbe or tool) are verified against known reference points to ensure their readings match expected values. Any deviations are corrected through software compensation or re-alignment.

Environmental Compensation

The system may apply corrections for temperature, humidity, or air turbulence, which can affect laser propagation and measurement accuracy.

Verification & Repeatability Testing

After calibration, the system is tested by measuring known points or performing repeatability checks to confirm accuracy and stability.
