Gyroscopic Mapping using Inertial Navigation Technology is rapidly becoming a widely accepted method for obtaining accurate XYZ data of subsurface utility infrastructure. Gyro-mapping has a number of advantages over traditional mapping that make it the more suitable and/or desirable technology in existing networks as well. One such aspect is the sampling frequency of 100Hz, or 100 samples per second. High frequency data enables accurate and highly detailed calculations of bend radius and grade measurement. Another key benefit is that gyro-mapping is not affected by electromagnetic noise, so it can be used right next to typical sources of interference such as high-voltage cables, rail tracks and sheet piling.

This presentation will introduce the audience to the concept, operational method, and data output of gyro-mapping technology, including:

1. How does an inertial navigation probe work?
2. Comparing Gyro-mapping to traditional mapping technologies: the pros and cons.
3. How can high frequency mapping enrich the knowledge of underground infrastructure?
