Hybrid Survey Networks : Combining Real-time and Static GNSS Observations for Optimizing Height Modernization

Creator:

Weaver, Brian Jerald

Abstract:

To derive ellipsoid heights on passive marks with cm-level accuracy, many current specifications require the collection and adjustment of long-duration, static Global Navigation Satellite System (GNSS) sessions. To increase efficiency, a survey procedure that includes real-time kinematic vectors from a real-time GNSS network (RTN) was evaluated. Thirty different “hybrid” networks...

Height Modernization from Static GPS Networks in Oregon: Evaluating NGS Guidelines and OPUS-Projects

Creator:

Kerr, Darren J.

Abstract:

Determining accurate elevations is important for many engineering and scientific applications, and finding these heights via GNSS increases efficiency and significantly reduces the costs as compared to precise geodetic leveling. The National Geodetic Survey (NGS) has published guidelines for determining both ellipsoidal and orthometric heights with GPS to within 2...
