Unit 3: Glaciers, GPS, and Sea Level Rise part of Measuring the Earth with GPS
GPS data can measure bedrock elevation change in response to the changing mass of glaciers. In this module, students will learn how to read GPS data to interpret how the mass of glaciers in Alaska and Greenland is ...

Unit 1: Collecting GPS Data part of Measuring the Earth with GPS
GPS data can measure vertical and horizontal bedrock motion caused by a variety of geologic processes, such as plate movement and the changing amount of water and ice on Earth's surface. In this unit, students ...

Measuring the Earth with GPS: Plate Motion and Changing Ice-Water part of Measuring the Earth with GPS
Although GPS's first widespread use by geoscientists was to track plate motions, geoscientists have found that GPS can also be used to measure local movement due to changes in the amount of water, snow, and ...

Unit 2: Earthquakes, GPS, and Plate Movement part of Measuring the Earth with GPS
GPS data can measure bedrock motion in response to deformation of the ground near plate boundaries because of plate tectonics. In this module, students will learn how to read GPS data to interpret how the bedrock ...

Unit 4: Groundwater, GPS, and Water Resources part of Measuring the Earth with GPS
GPS data can measure ground elevation change in response to the changing amount of groundwater in valleys and snow cover in mountains. In this module, students will learn how to read GPS data to interpret how the ...

Unit 3: Static GPS/GNSS Methods part of High Precision Positioning with Static and Kinematic GPS
The application of Global Navigation Satellite Systems (GNSS) in the earth sciences has become commonplace. GNSS data can produce high-accuracy, high-resolution measurements in common reference frames. Static GNSS ...

Unit 2: Kinematic GPS/GNSS Methods part of High Precision Positioning with Static and Kinematic GPS
The application of Global Navigation Satellite Systems (GNSS) in the earth sciences has become commonplace. GNSS data can be collected rapidly and compared in common reference frames. Real-time kinematic (RTK) GNSS ...

Unit 2.1: Measuring Topography with Kinematic GPS/GNSS part of High Precision Positioning with Static and Kinematic GPS
Kinematic GNSS surveys can provide a rapid means of collecting widely distributed, high-precision topographic data. The advantages of this technique over optical instruments such as a total station are that it only ...

Unit 2.2: Change Detection with Kinematic GPS/GNSS part of High Precision Positioning with Static and Kinematic GPS
Though it may be difficult to perceive, landscapes are constantly changing form and position. High-precision GNSS is one of a handful of techniques capable of quantifying these changes and is a key component of ...

Unit 1: GPS/GNSS Fundamentals part of High Precision Positioning with Static and Kinematic GPS
The constellations of satellites orbiting our planet enable high-precision positioning not just for consumer or survey applications but also for geoscience research such as detecting plate motions, landslide ...
