Product overview
The GTK (Shenzhen) Technology Co., Ltd. Multi-rotor UAV magnetic amplifier system combines magnetic measurement with ultra-low-altitude terrestrial gamma spectroscopy for uranium, thorium and potassium isotope detection. Its acquisition architecture integrates magnetic and playback data acquisition, shares one acquisition system with aeromagnetic acquisition, and supports DJI eport v2 data collection. The system incorporates a 670ML crystal and a data collector with ADC accuracy of greater than 24 bits. Energy resolution is better than 10% at the Cs137-662KeV peak.
Magnetic measurement covers 1000nT-100000nT with reading resolution of ≤0.0001nT and gradient tolerance of greater than 100nT/cm. Ground static noise is ≤0.01nT, while dynamic noise after compensation is ≤0.08nT. Fluxgate sensitivity is ≤0.02nT/√Hz in the 0.1- 100Hz frequency band using the power spectrum, and fluxgate frequency domain noise is ≤ 10pT rms/√Hz. The total weight of the magnetic discharge system is 4900g.
