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.

Urban Geography. All eight final-product ACs are participating, together with three other related groups. This talk will introduce the basics of GPS and satellites while focusing on: 1 How NGS determines where satellites are in orbit and how they move.

Lyrics to as time goes by

From recent knowledge of the parameters of the best fitting global ellipsoid, we know that the G96SSS geoid contains undulations biased from the non-tidal system by How do we achieve confidence with our Real Time RT work? Geoid change in Alaska is rapid and challenging to model. Su, X. Top, E. Currently, NGS is in the process of modernizing the NSRS, updating the existing horizontal datums with a suite of geometric reference frames and the vertical datums with a gravimetrically-derived geopotential datum. It will be superseded by the international foot definition i. Encoding and Querying Historic Map Content. We also show examples of antenna calibrations from the NGS facility. Adjusting all 9 SRPs offsets plus once-per-rev sines and cosines in each D,Y,B component for each satellite shows smaller mean subdaily, scale, and origin translation differences. It will end a dilemma that has persisted for over 60 years. The geoid over the US Rocky Mountains is computed using two different procedures. A distortion design criterion envelope is established for each zone, and it includes specific percentages of population, city and town locations, and total zone area. Although zone definitions will be available in , its official rollout will occur later along with the rest of NSRS Modernization.

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.

Urban Geography. Since the locations of the original could not be accurately located, a GPS-controlled survey was completed to develop a grid that spanned the same geographical region. This presentation discusses what that statement means, why it is done, and how it is achieved. The use of the VT network by positioning professionals has been steadily increasing, and it is anticipated that its use will begin to grow exponentially over the next couple of years. The presentation discusses the rational for modernizing as discussed in the year plan. The list includes: add GLONASS as well as GPS observations; adopt a new reference frame based on ITRF; update the IGS antenna calibrations based on the first reprocessing results and other sources; use the new EGM geopotential model with perhaps revised time-varying coefficients; implement a model for previously neglected higher-order ionospheric effects; consider the satellite dynamical effects of Earth albedo reflection and re-radiated thermal emissions; apply various refinements in modeling tropospheric delays; include station displacements due the S1 and S2 atmospheric pressure tides; use a new model for the subdaily EOP tidal variations, if available; reconsider the handling of EOP constraints and a prioris by ACs; incorporate all high-order relativistic effects; and revisit the treatment of all analysis constraints to remove as many as possible and to understand better the effects of those that remain. We therefore face a non-linear situation to maintain full consistency between all IGS products and the ITRF scale: each IGS frame contribution to ITRF based on one set of antenna calibrations must be used, together with frames from other techniques, to determine an updated ITRF and new antenna calibrations, which are then no longer strictly consistent with the starting IGS frame. Grounding Geographic Information. These use cases are intended to facilitate stakeholder feedback about necessary products or training, and serve as a starting point for those interested in pursuing detailed data-driven cases studies in the future. An airborne survey based out of Anchorage, AK covered an area x km over Cook Inlet and Kachemak Bay in 24 flights and about flight hours. Kiefer, P.
