Motion, Timing & Reference

Target group

This module deals with the basic working principles of motion and attitude sensors used in survey operations. It gives good insights of the techniques that are available and used for different types of survey work.  The second part Timing deals with the importance of time and timing of for survey systems. It gives an overview of timing techniques that are available and used for different types of survey work. 

Preliminary training

Using / knowledge of Attitude systems in actual practice or the Introduction to Hydrography course.
