Real Time GNSS Positioning Pt III

Real time GNSS networks (RTN) are the current high precision tool for many geospatial professionals for their cost savings and ease of use. This course will present information on using RTN, their advantages to traditional single base real time methods, and NGS goals to support their alignment to the National Spatial Reference System (NSRS).  NGS guidelines for RTN will be summarized, in particular how the RTN should obtain coordinates for their reference stations, and concerns for the RTN administrator and RTN user.  A brief discussion will be presented on the emerging precise point positioning (ppp) high precision methodology that will perhaps displace the role of the RTN in a decade or so.
