Abstract
We describe the application of Epoch-by-Epoch positioning to dam deformation monitoring at Metropolitan Water District’s Diamond Valley Lake, the largest water reservoir in southern California. Epoch-by-Epoch positioning is a new methodology whereby precise GPS positions can be estimated instantaneously with only a single epoch of dual-frequency phase and code data collected by two or more receivers over distances of several tens of km.
