Tau GeoSystems have spent several years developing intellectual property relating to the data processing of drone magnetic data that separates Tau GeoSystems TotalMag solution from competitors.
Most competitors don’t remove for manoeuvre noise due to many complicated factors. Tau GeoSystems has solved for these problems and can correct for the manoeuvre noise down to 0.1nT amplitude as shown in the figure below.
The effect of removing the manoeuvre noise is seen in this image. One flight in the middle has not had the data compensated. This is the difference in data quality between Tau GeoSystems and competitors. Clients are willing to pay a premium to receive a lower noise, higher quality magnetic map, as it directly affects their likelihood of discovering a mineral deposit.
The magnetometer bird is slung 20 to 40m under the drone. The magnetometer doesn’t see any electromagnetic noise from the drone producing a higher quality magnetic map.
