Book Description
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.

Pages : 62
Book Description
The magnetometer used in the payload of the DASA Project 6.27 Blue Goose Rocket is described. The instrument, a triaxial logarithmic second harmonic (flux-gate) magnetometer, measures three orthogonal components of magnetic fields in the range from 100 to 100,000 gamma. Included herein are the theory of the measurement, a description of the sensor and electronics, and the calibration of the instrumentation before integration into the payload. The details of the integration of this instrument into the rocket and the data recorded during the test flight will appear in future reports. (Author).
Hall-effect Magnetometers in Scientific Rocket Payloads

ISBN:
Category : Magnetometers
Languages : en
Pages : 32
Book Description
Two Hall effect magnetometers suitable for use in small rocket payloads have been designed and built. One of these is capable of measuring the components of the earth's magnetic field with resolution of a few tens of gammas. The other is a very simple instrument suitable for use as a rocket aspect sensor. Design considerations are discussed, the magnetometers developed are described, and the results of laboratory tests are given.

A System for Measuring Vector Magnetic Fields from Sounding Rockets
Author: P. G. ForsythPublisher:
ISBN:
Category : Geomagnetism
Languages : en
Pages : 20
Book Description
Tests of a newly designed operational system show that the earth's vector magnetic field can be measured from a sounding-rocket nose cone by (a) determining the attitude of a rocket nose cone by means of an electromagnetic attitude-sensor using antenna-array signal-strength patterns; (b) making vector magnetic measurements within the rocket nose cone by means of switched bias coils and a cesium vapor magnetometer; (c) encoding and telemetering the resulting information in a format compatible with the existing facilities; and (d) developing computational techniques for reducing the data obtained from the system.

First-Generation Jet Propulsion Laboratory "hockey-Puck" Free-Flying Magnetometers for Distributed In-Situ Multiprobe Measurement of Current Density Filamentation in the Northern Auroral Zone

Book Description
The sub-orbital rocket mission was a collaborative project between the University of New Hampshire, Cornell University, and the Jet Propulsion Laboratory (JPL) to study filamentation phenomena in the northern Auroral zone. The Enstrophy mission test flies the JPL Free-Flying Magnetometer (FFM) concept. The FFM technology development task has been funded by NASA develop miniaturized, low-power, integrated "sensorcrafts". JPL's role was to design, integrate, test, and deliver four FFMs for deployment from the sounding rocket, allowing a unique determination of curl-B. This provides a direct measurement of magnetic-field-aligned current density along the rocket trajectory. A miniaturized three-axis fluxgate magnetometer was integrated with a 4-channel 22-bit sigma-delta Analog to Digital Converter (ADC), four temperature sensors, digital control electronics, seven (Li-SOCl2) batteries, two (4 deg x 170 deg field of view) sun-sensors, a fan-shaped-beam laser diode beacon, a (16 MHz) stable Temperature Compensated Crystal Oscillator (TCXO) clock, Radio Frequency (RF) communication subsystem, and an antenna for approximately 15 minutes of operation where data was collected continuously and transmitted in three (3) bursts (approximately 26 seconds each) to ground station antennas at Poker Flat, Alaska. FFMs were stowed within two trays onboard the rocket during the rocket launch and were released simultaneously using the spinning action of the rocket at approximately 300 km altitude (approximately 100 sec. into the flight). FFMs were deployed with spin rate of approximately 17 Hz and approximately 3 m/sec linear velocity with respect to the rocket. For testing purposes while the rocket was in the launch pad and during flight prior to release of FFMs from the rocket, commands (such as "power on", "test", "flight", "power off', and clock "Reset" signal) were transmitted via a infrared Light Emitting Diode to an infrared

Book Description
This book gathers, for the first time, an overview of nearly all of the magnetic sensors that exist today. The book is offering the readers a thorough and comprehensive knowledge from basics to state-of-the-art and is therefore suitable for both beginners and experts. From the more common and popular AMR magnetometers and up to the recently developed NV center magnetometers, each chapter is describing a specific type of sensor and providing all the information that is necessary to understand the magnetometer behavior including theoretical background, noise model, materials, electronics, design and fabrication techniques, etc.
