RISComparative Analysis of Online Static GNSS Postprocessing Services
Publisher: American Society of Civil Engineers
Abstract: Several precise point positioning or relative positioning services are available online for postprocessing static global navigation satellite system (GNSS) data collected on a single mark. The accuracy of five services ...
Hybrid Survey Networks: Combining Real-Time and Static GNSS Observations for Optimizing Height Modernization
Publisher: American Society of Civil Engineers
Abstract: To derive ellipsoid heights on passive marks with centimeter-level accuracy, many current specifications require the collection and adjustment of long-duration, static, postprocessed global navigation satellite system ...
Improving TRANS4D’s Crustal Velocity Model for the Southeastern United States
Publisher: American Society of Civil Engineers
Abstract: AbstractThis paper introduces a new crustal velocity model for the southeastern United States.
This model supplements other velocity models currently residing in the TRANS4D software.
This new velocity model reveals ...
Tale of Two RTNs: Rigorous Evaluation of Real-Time Network GNSS Observations
Publisher: American Society of Civil Engineers
Abstract: Real-time networks (RTNs) have become popular for global navigation satellite system (GNSS) surveys because highly accurate positions can be derived in seconds to a few minutes compared with the many minutes and hours ...
