Below is a collection of NGS publicly-given presentations that have been collected for viewing by the public. You can also view a list of upcoming presentations by visiting the Upcoming and Recent Presentations Calendar. For more information contact ngs. NSRS Modernization has, and continues to be a significant undertaking. In addition to new paradigms related to datum definitions, it has also required NGS to rethink how we collect, process, store, manipulate, and deliver data. In this session, we will review the need, and status of the major projects associated with NSRS Modernization. Changes in technology and a better understanding of the dynamic earth have made it necessary to improve the NSRS to be of better use for modern applications.

There isn't currently a PDF version of the manual. We'd like to make it an option in the future, but we haven't got to that yet, and need to look into the best way to do it with the new wiki-based documentation system. The links at the top-right of the forum still point to the Opus 12 manual, but we'll be updating them. Maybe this could be considered: When user boots dopus first time a "Welcome to Directory Opus" dialog appears.

This requirement was instituted due primarily to the complexity of the application and the lack of user resource documents. If one or more of the topics sparks interest, the presentation will guide the user to the resources needed. However, noisier data can be accounted for using least squares collocation - missing signal due to gaps cannot be easily overcome. I end with a discussion of using atomic clocks for geodesy in the future. These will be surveys designed to independently measure the geoid to provide a check against both the data and theory used to create the final gravimetric geoid which will be used in the geopotential reference system. NGS also began investigating a new approach to defining the vertical datum through a high accuracy gravimetric geoid. The national shoreline provides critical baseline data for updating nautical charts; managing coastal resources; and defining U. Are there guidelines to follow to help us with our procedures? This talk covers hydraulic correctors, dynamic heights, orthometric heights, and instrumentation that is used in datum definition and access. This presentation is a short tale of two feet. An entirely new State Plane Coordinate System is also being developed. This course will describe the steps involved in processing the data using the various flavors of OPUS, will explain the output so that users can interpret and have confidence in the results and will provide some demonstrations on using OPUS.

What pitfalls should we avoid? Among the activities highlighted in this presentation are: improved coordinates for the CORS and a large subset of the passive mark networks NAD 83 and NA ; the related work to define a new hybrid geoid model providing improved consistency with these new coordinates and velocities GEOID12 ; the Gravity for the Redefinition of the American Vertical Datum GRAV-D mission to create a snapshot of gravity across the United States in unparalleled detail; the Online Positioning User Service OPUS providing virtually hands-off, high-accuracy GNSS data processing; and the creation of guidelines to help real-time network providers more rigorously tie their networks to the global and national datums. To focus on the dynamical aspects of the problem, nearly ideal conditions have been adopted by using IGS Rapid orbits as observations and known Earth orientation parameters EOPs. Since the datum value has already been agreed upon, the effort here will be to assess the implied MODT at the tide gauges to differentiate between local and global MSL. These models are verified against dense GNSS bedrock velocity measurements and tide gauge records. The results suggest that a 1 arc-minute grid size is sufficient for the 1-cm geoid, even for areas with very rough topography and high gravity variations. Global Navigation Satellite System GNSS data processing requires many different numerical models to describe the physical processes affecting the positions of the satellites and points on the ground as well as the propagation of the GNSS signals from the satellites to the user. Because the geoid changes in time, this model must account for geoid change signals of more than 1 cm on the timescale of a decade to maintain its accuracy. Future plans will be to increase the accuracy of the modeling, reduce the latency of the models and formalize the model as an official NOAA product.
