Magnetic Petrology Database for Interpretation Satellite Magnetic Anomalies

2005
A Global Magnetic Petrology Database (MPDB) is now being compiled at NASA/Goddard Space Flight Center and consists of many thousands of records. The prototype database is located at http://core2.gsfc.nasa.gov/research/terr_mag/php/MPDB/frames.html.

Magnetic satellite detumbling: The b-dot algorithm revisited

2015 American Control Conference (ACC), 2015
The 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 Fields of the Satellites of Jupiter and Saturn

Space Science Reviews, 2009
This 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.

Satellite Magnetic Map and Tectonic Correlation

Journal Geological Society of India, 1986
Abstract The satellite magnetic data (MAGSAT) over India is analysed with reference to the major tectonic elements of the country. The recorded magnetic anomaly varies from +6 gamma over the eastern part of the Indian shield to -9 gamma over the Himalayas. Deccan Trap is characterized by 'nosing' of the magnetic contours.

Interpretation of satellite elevation magnetic anomalies

Journal of Geophysical Research: Solid Earth, 1986
The 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

1968
One 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).

The Magnetic Torque Acting on Artificial Satellites

1963
The prediction and control of an artificial satellite’s orientation around its center of mass has become more and more important in the last few years for both manned and unmanned scientific space probes. Intensive studies of the torques acting on a satellite in orbit close to the earth have been made for the purpose of predicting, and sometimes for ...

Magnetic attitude actuation for passive satellites

IEEE Transactions on Magnetics, 1966
The orientation of a passive communications satellite with respect to the earth can be adjusted by using an electromagnetic actuator which is rigidly mounted on the structure of the satellite. The actuator consists of three mutually-orthogonal air-cored coils on the skin of the satellite.
