A new functional model is proposed for gravity field modeling on the basis of KBR data from the GRACE satellite mission. This functional model explicitly connects a linear combination of gravitational potential gradients with a linear combination of range-rate measurements at several successive epochs. The system of observation equations is solved in the least-squares sense by means of the pre-...

In this paper we explore the possibility of suitably combining the nodes Ω of the existing geodetic LAGEOS, LAGEOS II and Ajisai SLR satellites and of the radar altimeter Jason–1 satellite in order to increase, hopefully, the accuracy in testing the general relativistic gravitomagnetic Lense–Thirring effect in the gravitational field of the Earth. The proposal of introducing Jason–1 in such a c...

In this paper we show that by suitably combining the nodes Ω of the existing geodetic LAGEOS, LAGEOS II and Ajisai SLR satellites and of the radar altimeter Jason–1 satellite it would be possible to measure the general relativistic gravitomagnetic Lense–Thirring effect in the gravitational field of the Earth with a high accuracy and reliability. The proposal of introducing Jason–1 in such a com...

The choice of global geopotential model used in remove-restore technique for determination of regional quasigeoid from gravity data may affect the solution, in particular when the accuracy is supposed to reach a centimetre level. Global geopotential model plays also an important role in validating height anomalies at GPS/levelling sites that are used for the estimation of the external accuracy ...
