The coseismic geodetic signature of the 1999 Hector Mine earthquake
K. J. Hurst,Donald F. Argus,Andrea Donnellan,Michael Heflin,David C. Jefferson,Gregory A. Lyzenga,Jay Parker,Mark V. Smith,Frank Webb,James F. Zumberge +9 more
TL;DR: The M = 7.1 Hector Mine earthquake ruptured the Lavic Lake fault near Twentynine Palms, CA at 09:46 UTC October 16, 1999.
Journal ArticleDOI
Examining the C1-P1 pseudorange bias
TL;DR: In this article, a set of satellite-specific compensatory pseudorange offsets is calculated, and each is applied to a wee of daily global network analyses in which satlellite, receiver, atmospheric, and Earth rotation parameters are estimated.
Journal ArticleDOI
Rate change observed at JPLM after the Northridge Earthquake
Michael Heflin,Danan Dong,Andrea Donnellan,Ken Hurst,David C. Jefferson,Michael M. Watkins,Frank Webb,James F. Zumberge,Deborah Dauger,Gregory A. Lyzenga +9 more
TL;DR: In this article, the authors show that the geodetic rate of a permanent site in Pasadena, California (JPLM) changed significantly after the 17 January 1994 Northridge California earthquake, and that the direction and size of post-seismic displacements at JPLM are not consistent with additional slip on the fault which ruptured.

TL;DR: The MSL OD team developed spin signature removal tool and successfully used the tool during cruise, a novel approach was used for the MSL solar radiation pressure model and resulted in a very accurate model during the approach phase, the change in velocity for Attitude Control System (ACS) turns was successfully calibrated and with appropriate scale factor resulted in an improved velocity prediction for future turns, All Trajectory Correction Maneuvers were successfully reconstructed and execution errors were well below the assumed pre-fight execution errors, The official OD solutions were statistically consistent throughout cruise and for OD solutions with different
