Abitibi Geophysics together with GEM Systems announced about creation of the partnership AeroVision™ for using UAV magnetic system which explores two potassium sensors. The system is going to be available since June, 1. Sampling interval is promised 2 meters and resolution of .0001 nT, absolute accuracy +- 0.05 nT. Laser-altimeter, GPS and auto-pilot are included.
The UAV mag surveys cost is going to be over 50% of the present ground geophysics pricing.
Ivan Hrvoic, President of GEM, explains REQUIREMENTS FOR OBTAINING HIGH ACCURACY WIТН PROTON MAGNEТOMERS.
Absolute accuracy of а measurement is the difference between measured and true values. Obviously, nobody knows the true value, so we end up defining the limits we know the true value must be within. Absolute accuracy of а measurement is the difference between measured and true values.Obviously, nobody knows the true value, so we end up defining the limits we know the true value must be within. There are numerous difficulties and conditions that must be fulfilled to obtain that kind of absolute accuracy. Proton magnetometers, although theoretically of higher absolute accuracy, require tender care if the highest accuracy is ever to be achieved. The highest absolute accuracy of the magnetic field measurement has a metrological importance, but very little beyond this.
