This material was developed and reviewed through the GETSI curricular materials development process. This rigorous, structured process includes:

team-based development to ensure materials are appropriate across multiple educational settings.
multiple iterative reviews and feedback cycles through the course of material development with input to the authoring team from both project editors and an external assessment team.
real in-class or field camp/course testing of materials in multiple courses with external review of student assessment data.
multiple reviews to ensure the materials meet the GETSI materials rubric which codifies best practices in curricular development, student assessment and pedagogic techniques.

Summary

Part of GETSI Field Collection: In this module, students will learn the fundamentals of global navigation satellite systems (GNSS, a more universal term than GPS) and how to apply these techniques beyond answering, "Where am I?" This module teaches how high-precision positioning enables geoscientists to track changes in the surface of the earth that would otherwise be imperceptible. Through brief classroom lectures, demonstrations, and field exercises, students learn both kinematic and static positioning techniques. This module is field-focused, minimizing lectures and computer work and maximizing student time spent designing and implementing surveys as well as analyzing the new data. Most units require half to a full day to execute, although some waiting time may be required for post-processing satellite data. Some prepared data sets are available for courses unable to collect data directly. Instructors can request support for equipment loans and some types of technical assistance from EarthScope Consortium, which runs the NSF's Geodetic Facility.

Strengths of the Module

This field-focused module balances brief, technical skill-building exercises against more in-depth assignments that require students to use higher order thinking to solve issues regarding technique appropriateness, trouble-shooting, and data interpretation.
Units are written broadly so they can be applied in a variety of geologic settings and research questions. Most exercises can also be extracted from the module and used independently.
Students must apply aspects of the analysis to societal challenges, leading to greater engagement and understanding of why these types of studies are undertaken.
Quantitative skills are featured in the survey design - something often lacking in geoscience field courses.
Teaching resources include a variety tips for successfully implementing the module in real field environments, including ideas for picking field sites and keeping student occupied once in the field.
The skills learned regarding the collection and interpretation of GNSS data are practical in nature and can be valuable to both industry and research applications.
Can be easily used in a summer field camp or in an academic year course with field components. Alternatively, Prepared data sets allow classroom courses to conduct similar analyses, even if they are unable to go into the field.
