Abstract In situ magnetic field measurements are critical to our understanding of a variety space physics phenomena including field‐aligned currents and plasma waves. Unfortunately, high‐fidelity magnetometer often degraded by stray fields from the host spacecraft, its subsystems, other instruments. One dominant source interference on many missions reaction wheels—spinning platters varying rates used control spacecraft attitude. This manuscript presents novel approach mitigation wheel aboard...
Abstract. CASSIOPE/e-POP, now known as Swarm-Echo, was launched in 2013 to study polar plasma outflow, neutral escape, and the effects of auroral currents on radio propagation ionosphere. The e-POP suite contains an array eight instruments, including two fluxgate magnetometers a shared boom. Until now, relied set preflight calibrations, which limited accuracy magnetic field product magnetometers' utility for some applications. Here we present results situ calibration performed data from 3...
Abstract. Ongoing innovation in next generation fluxgate magnetometry is important for enabling future investigations of space plasma, especially multi-spacecraft experimental studies energy transport the magnetosphere and solar wind. Demonstrating spaceflight capability novel designs an step instrument development process; however, large-scale satellite missions are often unwilling to accept risks without flight heritage. The Tesseract – a magnetometer sensor design-had opportunity...
Abstract. Magnetometer measurements are one of the critical components necessary to improve our understanding intricate physical processes coupling mass, momentum, and energy within near-Earth space throughout solar system. However, these often contaminated by stray magnetic fields from spacecraft hosting field sensors, data requires application interference mitigation algorithms prior scientific use. Rigorous numerical validation techniques can be challenging when they applied in-situ...
