Journal ArticleDOI
Plate Motion of India and Interseismic Strain in the Nepal Himalaya from GPS and DORIS Measurements
Pierre Bettinelli,Jean Philippe Avouac,Mireille Flouzat,François Jouanne,Laurent Bollinger,Pascal Willis,Pascal Willis,Gyani Raja Chitrakar +7 more
TL;DR: In this article, the authors analyzed geodetically estimated deformation across the Nepal Himalaya in order to determine the geodetic rate of shortening between Southern Tibet and India, and determined the pole of rotation of the Indian tectonic plate to be located in ITRF2000 at 51.409±1.556°E, with an angular velocity of 0.483±0.015°.
Journal ArticleDOI
The angular velocities of the plates and the velocity of Earth's centre from space geodesy
Donald F. Argus,Richard G. Gordon,Michael Heflin,Chopo Ma,Richard J. Eanes,Pascal Willis,Pascal Willis,W. Richard Peltier,Susan Owen +8 more
TL;DR: In this article, a set of relative plate angular velocities, called GEODVEL (for GEODesy VELocity) is presented, which is based on the estimation of the position of the Earth's center and the assignment of sites to plates.
Journal ArticleDOI
GPS precise tracking of TOPEX/POSEIDON: Results and implications
Willy Bertiger,Yoaz Bar-Sever,E. J. Christensen,E. S. Davis,Joseph R. Guinn,Bruce J. Haines,R. W. Ibanez-Meier,J. R. Jee,S. M. Lichten,William G. Melbourne,Ronald J. Muellerschoen,Timothy N. Munson,Yvonne Vigue,S. C. Wu,T. P. Yunck,Bob E. Schutz,P. A. M. Abusali,Hyung-Jin Rim,Michael M. Watkins,Pascal Willis +19 more
TL;DR: A reduced dynamic filtering strategy that exploits the unique geometric strength of the Global Positioning System to minimize the effects of force model errors has yielded orbit solutions for TOPEX/POSEIDON which appear accurate to better than 3 cm (1 σ) in the radial component.
Journal ArticleDOI
First assessment of GPS-based reduced dynamic orbit determination on TOPEX/Poseidon
T. P. Yunck,Willy Bertiger,S. C. Wu,Yoaz Bar-Sever,E. J. Christensen,Bruce J. Haines,S. M. Lichten,Ronald J. Muellerschoen,Yvonne Vigue,Pascal Willis +9 more
TL;DR: The reduced dynamic Global Positioning System (GPS) tracking technique has been applied for the first time as part of the GPS experiment on TOPEX/Poseidon as mentioned in this paper.
Journal ArticleDOI
One-Centimeter Orbit Determination for Jason-1: New GPS-Based Strategies
TL;DR: The U.S. and French Jason-1 satellite is carrying a state-of-the-art GPS receiver to support precise orbit determination (POD) requirements as discussed by the authors.
