Demonstrating the space flight capability of the next generation of precise, reliable magnetic field instruments is important for enabling future space science missions that will further our understanding of the connection between earth’s magnetic field and the sun. Here, we present a new magnetic field instrument design called Tesseract, the results from its successful first space flight demonstration aboard a rocket, and its measurements of magnetic fields associated with the aurora.

We present an experiment intended to enable extremely low-noise magnetic field measurements. We manufactured fluxgate magnetometer cores using two metal alloys, two geometries, two foil thicknesses, and six different heat treatments and compared the resulting material properties, power consumption, and magnetic noise. Our results suggest that thinner foils, potentially using a new copper alloy, manufactured into continuous racetrack washers may provide excellent performance in fluxgate sensors.

Magnetic field measurements in space can be contaminated by stray magnetic fields from their host satellite. We present an automated tool for measuring the magnetic field generated by potential satellite and instrument components to identify those that may degrade the measurements taken on orbit. This tool is designed for use by the Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites (TRACERS) Small Explorers mission and is currently being used for mission design activities.

Spaceflight magnetic field measurements are often contaminated by interference from the host spacecraft. We present a new dataset to enable development and testing of interference mitigation schemes for spaceflight magnetic fields data. Over 100 hours of data, including laboratory-generated proxies for magnetic interference and geophysical signals, has been produced. A ground truth for the underlying interference is also provided, enabling rigorous quantification of data cleaning techniques.

The Swarm-Echo Satellite carries two magnetometers that allow us to obtain two independent measurements of the changes that occur in the Earth's magnetic field during events such as aurora. Magnetometers must be independently calibrated to ensure they remain accurate. If no magnetic reference is available, a model magnetic field must be used. This paper discusses the method used to calibrate the magnetometers on Swarm-Echo and shows the improvements the calibration has made to the data product.

Fluxgate magnetometers provide magnetic field measurements for geophysics and space physics. A low-noise ferromagnetic ring core typically determines the noise performance of the instrument. Much of the basic research into producing low-noise fluxgate sensors was completed in the 1960s for military purposes and was never publicly released. We present a manufacturing approach that can consistently produce fluxgate ring cores with a noise performance comparable to the legacy ring cores used today.

Measurements from the magnetic field instrument on the Cassiope spacecraft were found to be degraded by an artifact of how the instrument tracks the changing magnetic field as the spacecraft orbits the Earth. We present a process to characterize this effect on orbit and compensate for it in the post–processing of the data. This work allows the instrument to accurately track rapidly changing local fields without loss of measurement fidelity and improves the high–frequency noise of the data.

We present a proof-of-concept space-flight instrument that can simultaneously make measurements of both the low- and high-frequency local magnetic field. Previously, this would have required two separate instruments that would normally have had to be mounted separately on long deployable booms to keep them from interfering. This new hybrid instrument is expected to be particularly useful on extremely small spacecraft, such as CubeSats, which can only accommodate a few instruments.

Fluxgate magnetometers are an important geophysical tool but are typically sensitive to changes in sensor temperature. We used a novel, low-cost calibration procedure to compare six matched sensors in which the material used as the mechanical support is varied and found that 30 % glass-filled PEEK engineering plastic is a good candidate for sensors. It is more economical, easier to machine, lighter, and more robust than historically used machinable ceramic.

Geomagnetic observatories are dedicated to the long-term monitoring of the Earth's magnetic field. Their time series contain information mainly about the Earth's core and the near-Earth space environment. MOSFiT accesses a global database with the most recent observatory data and allows us to separate the information about the Earth's core. At the same time, it allows for an efficient check of the data quality. We present the code, validate it and explain its usage.

AERO and VISTA spacecraft will use commercial magnetometers to measure space weather events near Earth’s aurora. The small size of AERO and VISTA necessitate the use of magnetometers with small size, weight, and power. The magnetometers selected exhibit good precision, but additional calibration is needed to achieve good accuracy. This work evaluates a method for calibration by regression which has reduced the magnetic observed error by a factor of ca. 50, meeting mission requirements.

The design, characteristics, and performance of a CubeSat magnetometer board (Quad-Mag) equipped with four PNI RM3100 magnetometers is presented. The inclusion of four sensors allows a potential factor of 2 reduction in the noise floor established for an individual sensor via oversampling with multiple sensors. The Quad-Mag is shown to enable 1 nT magnetic field measurements at 1 Hz and 5.345 nT at 65 Hz using commercial off-the-shelf sensors for space applications.

The commercial off-the-shelf (COTS) PNI RM3100 magnetometer was tested for single-event latchup (SEL) at Lawrence Berkeley National Laboratory's heavy-ion beam and did not experience any single-event effects at a linear energy transfer >75 MeV cm2 mg−1. Coupled with previous total ionizing dose (TID) testing at the University of Michigan and NASA Goddard Space Flight Center that showed no degradation in performance up to 150 kRad(SI), the COTS PNI RM3100 is extremely radiation tolerant.

The Low Orbit Pearl Satellites measure magnetic field with high spatial coverage. Although there is no magnetic cleanliness to the satellites, the triple sensor configuration enables removal of interference. Results show they can capture the Earth’s internal as well as external fields from the magnetosphere–ionosphere current system. This study implies that a large number of small low-cost satellites without magnetic cleanliness could be the future for space magnetic exploration.

The systematic error of calibrated fluxgate magnetometer data is studied for a spinning spacecraft. The major error comes from the offset uncertainty when the ambient magnetic field is low, while the error represents the combination of non-orthogonality, misalignment to spacecraft reference direction, and gain when the ambient field is high. The results are useful in developing future high-precision magnetometers and an error estimate in scientific studies using magnetometer data.

One of the four Galilean moons of Jupiter, Europa, is one of the most promising places in the solar system to find life outside Earth. For this reason, the space science community is currently focused on exploring it. One of the main difficulties of such a task is the harsh radiation environment caused by the radiation belts of Jupiter. In this paper, we present results for a magnetic field sensor being exposed to radiation levels similar to those expected at the surface of Europa.

We propose a gradiometer-based technique for cleaning multi-sensor magnetic field data acquired on board spacecraft. The technique takes advantage on the fact that the maximum-variance direction of many AC disturbances on board spacecraft does not change over time. We apply the proposed technique to the SOSMAG instrument on board GeoKompsat-2A. We analyse the performance and limitations of the technique and discuss in detail how various disturbances are removed.

Measuring the magnetic field onboard spacecraft requires regular in-flight calibration activities. Among those, determining the output of magnetometers under vanishing ambient magnetic fields, the so-called magnetometer offsets, is essential. Typically, characteristic rotations in solar wind magnetic fields are used to obtain these offsets. This paper addresses the question of how many solar wind data are needed to reach certain accuracy levels in offset determination.

Our knowledge of the Earth's magnetic field arises from magnetic signals stored in lavas. In rugged volcanic terrain, however, the magnetization of the underlying flows may influence the magnetic field as recorded by newly formed flows on top. To measure these local magnetic anomalies, we developed a low-cost field magnetometer with superior accuracy and user-friendliness. The first measurements on Mt. Etna show local magnetic variations that are much larger than expected.

We highlight the development of a low-cost portable sensor array to study magnetic fields in urban areas. Recent advancements in urban science have demonstrated significant utility in characterizing a city based on physical measurements. Magnetic fields of cities are characterized by significant noise; in the case of the San Francisco Bay Area, this noise is dominated by the BART train system. We demonstrate an ability to identify and extract BART noise from the urban magnetic environment.

Raw output of spacecraft magnetometers has to be converted into meaningful units and coordinate systems before it is usable for scientific applications. This conversion is defined by 12 calibration parameters, 8 of which are more easily determined in flight if the spacecraft is spinning. We present theory and advanced algorithms to determine these eight parameters.

We present a proof-of-concept space-flight instrument that can simultaneously make measurements of both the low- and high-frequency local magnetic field. Previously, this would have required two separate instruments that would normally have had to be mounted separately on long deployable booms to keep them from interfering. This new hybrid instrument is expected to be particularly useful on extremely small spacecraft, such as CubeSats, which can only accommodate a few instruments.

The presence of magnetic fields in space dominate the way planets interact with different types of plasmas. Thus, measuring them is extremely important when studying space. We present an instrument capable of measuring magnetic fields at a fraction of the cost, power and size of traditional magnetometers. With this technology, a science-grade magnetometer for small satellites can be achieved, enabling the study of the space environment with large clusters of sensors in future missions.

The long-term drift of magnetometers at geomagnetic observatories is calibrated by a non-magnetic theodolite. We propose a numerical method to evaluate such absolute measurements in a new, more general manner. It is more flexible and helps to identify and correct or discard erroneous measurements. We derive this method and give examples showing how it improves the quality and reliability of the calibrations parameters (the so-called baseline values) of an observatory magnetometer.

In magnetic observatory data, according to the INTERMAGNET definitive 1 s data standard, the fluxgate magnetometer self noise usually covers the natural signal for frequencies higher than about 30 mHz. We present a numerical method how to merge the data with induction coil data in order to drastically reduce noise and to fill the entire possible bandwidth with information on the earth magnetic field. In spectrograms we visualize interesting phenomena revealed with the method.

Fluxgate magnetometers are an important geophysical tool but are typically sensitive to changes in sensor temperature. We used a novel, low-cost calibration procedure to compare six matched sensors in which the material used as the mechanical support is varied and found that 30 % glass-filled PEEK engineering plastic is a good candidate for sensors. It is more economical, easier to machine, lighter, and more robust than historically used machinable ceramic.

In geophysics exploration, measuring earth's magnetic field using magnetometers is a necessity to resolve earth's subsurface structure. In this paper we offer an open-schematic fluxgate magnetometer (Magnetogama) that will help people build their own magnetometer. We focus on how to assemble and record earth's magnetic response. Several sensitivity tests were performed to make sure that Magnetogama has the capability to be used in exploration.

The authors developed and built a digital non-magnetic declination–inclination magnetometer which gives all measurement data in digital form. Use of this instrument significantly decreases the possibility of observation errors and minimises handwork. We showed that this device is suitable for absolute magnetic control measurements, and it is more convenient, user friendly and effective than the traditional ones.

Commercial solutions for an automated DI-flux are practically reduced to the AutoDIF and the GyroDIF. We analyze the pros and cons of both in terms of suitability at the Livingston Island geomagnetic observatory, Antarctica. We conclude that the GyroDIF is more suitable for harsh conditions due to its simpler infrastructure. We also show the instrument housing design and its control electronics. Our experiences can benefit the geomagnetic community, which often faces similar challenges.

The present manuscript is written as the result of an exhaustive field work with MOURA instrument on relevant sites on Earth. MOURA magnetometer was developed for Mars MetNet precursor mission to Mars. In this work we have demonstrated the capabilities of the instrument in terrestrial analogues of Mars, which cover a huge variability range in the magnetic anomalies intensities. Apart from its suitability for prospections, we insist on its advanced performance regarding paleomagnetic information.

In situ magnetometry is key for planetary mineralogy. However, since magnetic instrumentation is considered secondary in Mars and Moon landers and rovers, magnetometers have often very restricted envelopes of mass, volume and power, and consequently limited functionality.
In this work, it is presented the capability of MOURA small magnetometer and gradiometer to open a wide and novel scientific research on Mars mineralogy and paleomagnetism through the very complex calibration process.

Short summary
The ability to make reliable magnetic measurements in space is very important for a broad range of applications in space science. Here, we present the design and performance of a new magnetometer that looks very promising for making stable reliable magnetic measurements in space. We show that Tesseract performs better than the traditional ring-core design in metrics that are associated with stability.
