GPS Positioning and Accuracy
Explanation of the Positioning and Accuracy of GPS and GNSS. This two-video series explains how GPS/GNSS receivers determine a position. The videos also include what factors determine the position's accuracy. The series also describes improving accuracy by "augmenting" the GPS position. The series also consists of a refresher on Latitude and Longitude. These videos are also included in the more comprehensive series Hydrographer's Toolbox.
