Download or read book Fluxgate Magnetometers for Space Research written by Günter Musmann and published by BoD – Books on Demand. This book was released on 2010 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: All fluxgate magnetometers are based on the theory of H.Aschenbrenner and G.Goubau developed in 1936 and the first fluxgates developed by F.Förster.Already the early satellites like putnik 3(Dolginov-Russia,1958), Mariner 4 (NASA/USA,1964), the first German satellite AZUR (Musmann, 1969) studying the magnetic fields of the Earth, Moon, Venus, Mars and other planets were using fluxgate magnetometers up to the latest NASA/ESA investigations on CASSINI (1998), and ESA's Rosetta(2004) and the first Ion Engine spacecraft\, NASA-DEEP-SPACE-ONE(Musmann/Kuhnke,1998), (see cover.) Very precise Earth magnetic field measurements in space have been made using fluxgate magnetometers in combination with scalar magnetometers (MAGSAT-Acuna,1979;OERSTED -Primdahl,1999;CHAMP-Lühr,2000) Only a few detailed descriptions about the theory and how to design and calibrate space fluxgate magnetometers and how to get reliable accurate magnetic field component measurements in space have been published.Therefore the worldwide small space fluxgate magnetometer community decided to document and save all their relevant know-how on space fluxgate magnetometers in this book before retirement.

Available in PDF, EPUB and Kindle. Book excerpt: This completely updated second edition of an Artech House classic covers industrial applications and space and biomedical applications of magnetic sensors and magnetometers. With the advancement of smart grids, renewable energy resources, and electric vehicles, the importance of electric current sensors increased, and the book has been updated to reflect these changes. Integrated fluxgate single-chip magnetometers are presented. GMR sensors in the automotive market, especially for end-of-shaft angular sensors, are included, as well as Linear TMR sensors. Vertical Hall sensors and sensors with integrated ferromagnetic concentrators are two competing technologies, which both brought 3-axial single-chip Hall ICs, are considered. Digital fluxgate magnetometers for both satellite and ground-based applications are discussed. All-optical resonant magnetometes, based on the Coherent Population Trapping effect, has reached approval in space, and is covered in this new edition of the book. Whether you're an expert or new to the field, this unique resource offers you a thorough overview of the principles and design of magnetic sensors and magnetometers, as well as guidance in applying specific devices in the real world. The book covers both multi-channel and gradiometric magnetometer systems, special problems such as cross-talk and crossfield sensitivity, and comparisons between different sensors and magnetometers with respect to various application areas. Miniaturization and the use of new materials in magnetic sensors are also discussed. A comprehensive list of references to journal articles, books, proceedings and webpages helps you find additional information quickly.

This book was released on 1986 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: A software package has been designed to simulate the operation of the fluxgate magnetometer to be flown on the Combined Release and Radiation Effects Satellite (CRRES). Algorithms are presented to create a one-second averaged data base from a simulated data stream from a spinning satellite in a realistic earth's magnetic field. Methods are devised to perform on-orbit calibration, to despin the data and to use a model field for calibration. Expressions are presented for both the signals and errors in signals introduced by inaccurate calibration parameters. The time requirement for processing are estimated. Keywords: Spacecraft Magnetometer; Simulation software; Magnetometer calibration; Data processing; Satellite instrumentation.

Available in PDF, EPUB and Kindle. Book excerpt: J.L. Burch·V. Angelopoulos Originally published in the journal Space Science Reviews, Volume 141, Nos 1–4, 1–3. DOI: 10.1007/s11214-008-9474-5 © Springer Science+Business Media B.V. 2008 The Earth, like all the other planets, is continuously bombarded by the solar wind, which is variable on many time scales owing to its connection to the activity of the Sun. But the Earth is unique among planets because its atmosphere, magnetic eld, and rotation rates are each signi cant, though not dominant, players in the formation of its magnetosphere and its reaction to solar-wind inputs. An intriguing fact is that no matter what the time scale of solar-wind variations, the Earth’s response has a de nite pattern lasting a few hours. Known as a magnetospheric substorm, the response involves a build-up, a crash, and a recovery. The build-up (known as the growth phase) occurs because of an interlinking of the geom- netic eld and the solar-wind magnetic eld known as magnetic reconnection, which leads to storage of increasing amounts of magnetic energy and stress in the tail of the mag- tosphere and lasts about a half hour. The crash (known as the expansion phase) occurs when the increased magnetic energy and stresses are impulsively relieved, the current system that supports the stretched out magnetic tail is diverted into the ionosphere, and bright, dynamic displays of the aurora appear in the upper atmosphere. The expansion and subsequent rec- ery phases result from a second magnetic reconnection event that decouples the solar-wind and geomagnetic elds.
Download or read book Simulation and Optimization of Micromachined Magnetic Fluxgate Sensors written by Sukirti Gupta and published by . This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluxgate sensors are one of the most versatile magnetic field sensors, offering very reliable field measurement from mT to sub uT region, with very high resolution. Vector magnetic field measurements of better sensitivity are only possible with quantum affects based magnetometer SQIUD' (super conducting quantum interference device). These sensors require superconductive material for the field detection, which can be maintained only at extremely low temperature ( -1980 C). Hence SQUID, based systems are very fragile, bulky and costly in operation. The above-mentioned shortcomings of SQUID sensors leave fluxgate as the best choice for the applications, where available space and power is limited (ex. satellite, submarines). The objective of this research is to analyze and optimize these micro-machined magnetic fluxgate sensors for high sensitivity and directionality at low excitation current. For advanced applications, fluxgate sensor should offer high magnetic field sensitivity as well as directionality. There has been a large demand for the integrated fluxgate sensors containing sensor and the supporting circuit on the same chip. Since CMOS circuits have driving current limitations, main motivation of this research is to optimize sensor core geometry to achieve high sensitivity and directionality at low operating current In this work, first, fluxgate sensors have been simulated by help of finite element analysis. Complete sensor response can be obtained by these simulations and hence different sensor designs can be analyzed before fabrication. In this work by changing the core shape, excitation current of the sensor has been reduced multiple times, which results in drastic reduction in overall power consumption. Different core geometries are also analyzed for directionality optimization. After finite element analysis, fluxgate sensors have been simulated and analyzed by the help of an innovative SPICE model. By simulating the sensor in SPICE, an integrated sensor response can be analyzed before fabrication and complete system optimization can be achieved. An innovative SPICE model for ring-core type fluxgate sensor has been developed, which includes saturation and hysteresis phenomenon of magnetic core. The presented model has been successfully applied to fabricated ring-type fluxgate sensors and very good matching has been observed between the simulated and measured values.
