This course guides field personnel performing GPS surveys for typical construction and civil works projects. The primary emphasis is on performing static and kinematic carrier phase differential GPS measurements. Absolute/autonomous and differential code phase GPS positioning and mapping techniques are also covered. Detailed field instructions for specific GPS receivers are typically contained in the operating or reference manuals provided by the manufacturer.

Given the wide variety of GPS receivers, coupled with the different types of data collection, logging, processing, and adjustment techniques that can be performed in the field, this course provides a brief overview of representative systems and highlights observing criteria common to all types of GPS equipment.
