• compact low-cost fluxgate 3 axis-magnetometer
• excitation of fluxgates: generation
of excitation
waveforms and synchronisation signals (DAC, DDS..)
• effects of phase noise in sync. signal while using synchronous detection
• (dis)advantages of digital synchronous detection
• sampling techniques of measurement of magnetic materials properties

Some recently finished projects at our laboratory:
• MIMOSA satellite magnetometer
• DIMADS magnetometer - bomb locator
• patented „racetrack“ fluxgate sensor
Current projects :
• Fluxgate magnetometer using gated integrator
• Navigational tool for drilling (using above)
• Sinewave current excitation unit for fluxgates
