Analysis of POGS Satellite Magnetic Data
Exploration Geophysics, 1993Results of a preliminary analysis of POGS satellite magnetic data to degree and order 10 are given, assuming a field of internal origin only. POGS data were made available in 19 files, each containing approximately ten days of observations made every ten seconds.

Magnetic attitude control for synchronous satellites
IEEE Transactions on Automatic Control, 1968Techniques using active magnetic coils have been studied for the attitude control of long-life vehicles in synchronous equatorial orbits, Analysis and computer simulation were followed by laboratory tests to investigate various control laws and methods of damping.

Magnetic Fields of the Satellites of Jupiter and Saturn
Space Science Reviews, 2009This paper reviews the present state of knowledge about the magnetic fields and the plasma interactions associated with the major satellites of Jupiter and Saturn. As revealed by the data from a number of spacecraft in the two planetary systems, the magnetic properties of the Jovian and Saturnian satellites are extremely diverse.

Magnetic satellite detumbling: The b-dot algorithm revisited
2015 American Control Conference (ACC), 2015The first task a spacecraft attitude control system must perform after separation from the launcher is to detumble the spacecraft, i.e., to bring it to a final condition with a sufficiently small angular momentum. Magnetic control has been used for decades to fulfill this task, typically using the socalled b-dot control law (in all its variants ...

Magnetic field experiment on the SUNSAT satellite
Journal of Geodynamics, 2002Abstract On Tuesday 23 February 1999, at 10:29 UTC, SUNSAT was launched into an 857×655 km, 96.47° polar orbit on a Boeing-Delta II rocket from Vandenberg Air Force Base in California, USA. Both SUNSAT and Orsted were NASA-sponsored secondary payloads accompanying the USA Air Force Argos satellite.

Interpretation of satellite elevation magnetic anomalies
Journal of Geophysical Research: Solid Earth, 1986The magnetic field satellite Magsat obtained total field data over almost the whole of the earth. We have studied these data in two different ways. The first way was to use spherical harmonic coefficients. It is often believed that these coefficients can be separated into those originating within the core of the earth and those from the crust at about ...

Satellite Studies of the Earth’s Magnetic Tail
1968One consequence of the interaction between the solar wind and the geomagnetic field is a deformation of the magnetosphere such as to produce a magnetospheric tail that extends away from the sun. The existence of the Earth’s magnetic tail was anticipated theoretically by Piddington (1960) and by Dungey (1961, 1963).
