Applications of satellite and marine geodesy to operations in the ocean environment [PDF]

open access: yes
The requirements for marine and satellite geodesy technology are assessed with emphasis on the development of marine geodesy. Various programs and missions for identification of the satellite geodesy technology applicable to marine geodesy are analyzed ...

A Java Program Generating Barycentric Observer Velocities from JPL Ephemerides

open access: yes, 2022
This works presents a program which computes velocities of an Earth-bound observatory in the reference frame of the barycenter of the solar system. It feeds from ephemerides files of the Jet Propulsion Laboratory to extract the velocity of the geocenter,

GeoDisFusion: Multitrack InSAR Fusion for Urban Geometric and Displacement Datum Integration

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
This article presents GeoDisFusion, a novel postprocessing framework for multitrack InSAR point cloud fusion. The method addresses two challenges: first, geometric height reference inconsistencies and, second, temporal displacement datum mismatches.

Developing an acceptance test for non-hydrographic airborne bathymetric lidar data application to NOAA charts in shallow waters [PDF]

open access: yes, 2013
Hydrographic data of the National Oceanic and Atmospheric Administration are typically acquired using sonar systems, with a small percent acquired via airborne lidar bathymetry for nearshore areas.

Global detailed geoid computation and model analysis [PDF]

open access: yes
Comparisons and analyses were carried out through the use of detailed gravimetric geoids which we have computed by combining models with a set of 26,000 1 deg x 1 deg mean free air gravity anomalies.

ALB Evaluation for NOAA charting requirements [PDF]

open access: yes, 2013
The National Oceanic and Atmospheric Administration (NOAA) acquires hydrographic data around the coasts of the US and its territories using in-house surveys and contracting resources. Hydrographic data are primarily collected using sonar systems, while a
