Modelling of the ring current in Saturn's magnetosphere
Abstract. The existence of a ring current inside Saturn's magnetosphere was first suggested by Smith et al. (1980) and Ness et al. (1981, 1982), in order to explain various features in the magneticExpand

A regular period for Saturn's magnetic field that may track its internal rotation
The rotation rate of a planet is one of its fundamental properties. Saturn's rotation, however, is difficult to determine because there is no solid surface from which to time it, and the alternativeExpand

Cassini Magnetometer Observations During Saturn Orbit Insertion
Cassini's successful orbit insertion has provided the first examination of Saturn's magnetosphere in 23 years, revealing a dynamic plasma and magnetic environment on short and long time scales. ThereExpand

Rotation rate of Saturn's interior from magnetic field observations
[1] Analysis of magnetic field data from the Pioneer 11, Voyager 1 and Voyager 2 spacecraft produced the first models of Saturn's internal field. One striking feature of these models is the lack ofExpand

Doppler Measurements of the Quadrupole Moments of Titan
Abstract Measurements of the Doppler frequency change in a microwave beam sent to and transponded back from an interplanetary spacecraft are very sensitive to the quadrupole gravitational field of aExpand

Modelling of magnetic field measurements at Mercury
Abstract Mapping Mercury's internal magnetic field with a magnetometer in closed orbit around the planet will provide valuable information about its internal structure. By measuring magnetic fieldExpand

Cassini observations of planetary‐period magnetic field oscillations in Saturn's magnetosphere: Doppler shifts and phase motion
[1] Cassini magnetic field observations show that few-nT oscillations near the planetary rotation period, first observed in Pioneer-11 and Voyager-1 and -2 fly-by data, are essentially ubiquitous inExpand

Estimating Mercury's 88-day libration amplitude from orbit
In this paper it is derived that the libration of Mercury can be described by � = � 0 sin M + � 0=K sin 2M where � 0 is the unknown libration amplitude, M is Mercury’s mean anomaly and K = −9:483. �Expand

Measurement of the PPN Parameter (gamma) with radio signals from the Cassini Spacecraft at X- and Ka-Bands
Radio Doppler data from the Cassini spacecraft during its solar conjunction in June 2002 can be used to measure the bending of light by solar gravitation. In terms of the standard post-NewtonianExpand
