Overview Edit

The NGA has developed the Estimation and Prediction of Orbits and Clocks to High Accuracy (EPOCHA) real-time software for GPS orbit/clock estimates, which enables the capability for potentially higher accuracy GPS positioning for many platforms. Using the NGA EPOCHA products could provide more current, higher rate information to improve position estimates. The concept has been demonstrated in post-processing, and the results confirm the improved accuracy; decisions regarding incorporating it within existing or future systems have yet to be made.[1]
