OPUS provides the user the means to obtain accurate coordinates while operating a single GPS receiver. A popular utility, OPUS is now processing over 20,000 user-submitted data sets per month. OPUS is designed to handle long baselines but requires relatively long (at least 2 h) tracking sessions to produce coordinates to within an

The National Geoodetic Survey provides the framework for all positioning activities in the Nation. NGS's authoritative spatial data, models, and tools are vital for the protection and management of natural and manmade resources and support the economic prosperity and environmental health of …
