NGS Releases CORS Positioning Upgrade for User Review and Testing

NGS released a significant upgrade to its Continuously Operating Reference Stations (CORS) for user review and testing. CORS provides GPS data to support very accurate 3D positioning, meteorology, space weather, and geophysical applications in the U.S. The upgrade provides improved positional coordinates and velocities. In a few weeks, NGS will replace its current geoid model with one that has improved height data. The geoid is a model of global mean sea level that is used to measure precise surface elevations. Combined with the CORS upgrade, this model will improve understanding of the effects of tectonic movement on local geographic coordinates.
