GEOG 352:

GNSS In the Geosciences

Surveying Bonfire Memorial on Texas A&M Campus using feature layers (Click link for the full interactive map!).

Course Description

This course introduces students to the theory and operation of Global Navigation Satellite Systems (GNSS) and Global Positioning Systems (GPS), and the application of GNSS for solving research problems common in the Geosciences. Geodesy will be covered in depth. GPS technology is introduced through a review of the fundamental concepts of coordinate systems and geodesy, followed by an in-depth discussion of signal propagation, signal processing, and the limitations of both handheld and differential GPS units. This is followed by a discussion about measurement strategies and an overview of how GPS is used in Geosciences.

Course Learning Outcomes:

Describe and calculate Geodetic Coordinate Systems, Datums, Conversions, and Transformation.
Name, describe and compare traditional georeferencing, mapping, tracking, navigation, and survey techniques.
Describe the technology used in Global Navigation Satellite Systems (GNSS), explain how a GNSS system works, and what the limitations are for handheld and differential GPS units.
Apply GNSS technology and appropriate measurement strategies to design, collect, and analyze research problems common in Geosciences.

Investigating Horizontal Datums and applying conversion and transformation methods, analyzing industry error, and map coordinate locations on a map.
