Designing a miniaturized fluxgate magnetometer
Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
SMILE (Small Magnetometer In Low-mass Experiment) is a digital fluxgate magnetometer designed with miniaturization as a goal. The instrument is intended asa payload for the Microlink (previously Nanospace) satellite. SMILE operates onsimilar principles as the magnetometer onboard Astrid-2 satellite. The magnetic fieldcomponents are extracted from the pick-up signal by means of digital correlation witha set of reference coefficients. An important difference from the Astrid-2magnetometer is that the digital signal processing previously done in threeprocessors (one for each axis) has been replaced with a single FPGA to achieve asmaller circuit board area. A new miniaturized fluxgate sensor with volumecompensation produced by the Lviv Center of Institute of Space Research is used inthe design. A prototype board was designed and built at the Royal Institute of Technology.Gateware suitable for calibration has been completed. Gateware for the operationalinstrument is still in its final stage of development.
