• 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

6th Summer School on “ADC & DAC Metrology”

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
