New-Sense will often use multiple base stations during flight operation for redundancy and confirmation of measurements. The GEM Systems GSM-19 system is an all in one unit with a ground magnetometer absolute accuracy of +/- 0.1 nT.

Base station location is either inside or near the survey flight area, in an area of low magnetic gradient and free from cultural electric and magnetic noise sources. This is to ensure accurate removal of diurnal noise from flight data. New-Sense synchronizes it’s base station data using a GPS clock.
