TL;DR: Evaluation of the intrinsic quality of the new DORIS Terrestrial Reference Frame shows that the addition of data from the new missions equipped with the latest generation of DORis receiver results in an internal position consistency of 10 mm or better after mid-2008.

TL;DR: In this article, a data set of DORIS station coordinates defined for specific time intervals called DPOD2005 is computed for precise orbit determination of altimetry missions, which is an extension of ITRF2005.

TL;DR: In this paper, the authors analyzed the available radio tracking data of previous NASA lunar orbiters and solved for the coefficients of a spherical harmonics expansion of the lunar gravity potential up to degree and order 150.

TL;DR: The Earth Gravitational Model 1996 (EGM96) as discussed by the authors was developed by the NASA Goddard Space Flight Center (GSFC), the National Imagery and Mapping Agency (NIMA), and The Ohio State University.

TL;DR: In this article, the authors used range rate and range measurements from X-band and, when available, Ka-band tracking systems of the Mars Reconnaissance Orbiter (MRO) spacecraft to improve knowledge of the static structure and characterize the temporal variability of the Martian gravitational field relevant to the planet's internal dynamics, the structure and dynamics of the atmosphere and the orbital evolution of spacecraft at Mars.
