GGM02 - An Improved Earth Gravity Field Model from GRACE
Byron D. Tapley,John C Ries,Srinivas Bettadpur,Don P. Chambers,Minkang Cheng,Francis Condi,Brian Gunter,Zhigui Kang,Peter Nagel,R. Pastor,T. Pekker,S. R. Poole,Furun Wang +12 more
TL;DR: A new generation of Earth gravity field models called GGM02 are derived using approximately 14 months of data spanning from April 2002 to December 2003 from the Gravity Recovery And Climate Experiment (GRACE) as discussed by the authors.

Journal ArticleDOI
Precise orbit determination for the GRACE mission using only GPS data
TL;DR: In this paper, the authors investigate how well the orbits of the GRACE satellites (about 470 kilometres in altitude) can currently be determined using only GPS data and based on the current models and methods.
Journal ArticleDOI
Precise orbit determination for GRACE
Zhigui Kang,Peter Nagel,R Pastor +2 more
TL;DR: In this paper, the authors describe the use of the data collected by the GPS receiver, high precision accelerometer observations and precise attitude data from star trackers in the application of the GRACE Precise Orbit Determination (POD).
Journal ArticleDOI
Precise orbit determination for GRACE using accelerometer data
TL;DR: In this article, the authors investigate how well the GRACE satellite orbits can be determined using improved accelerometer data and to assess the differences between the use of accelerometers data and the use a priori models for the surface forces.
