GTK-M13 aeromagnetic detection system
Aeromagnetic detection system based on Bartington Mag13 fluxgate probe
----------------------------------------------
1.system has that advantage
l The system is extremely light, and the system weighs only0.5kg(excluding installation connection components and batteries)
l Aeromagnetic measurement data is wirelessly transmitted back to the ground station in real time for real-time display
l The magnetometer and the drone are hard-connected, using a retractable carbon fiber rod
l The patented compensation algorithm greatly improves the accuracy of the three-axis vector high-precision magnetometer and greatly reduces system noise.
two。Patent compensation technology
fluxgate magnetometer12parameter numbercompensation算法，GetAxial interference,Scale factor, orthogonality errorAnd12 modified parameters for Soft Iron Effects,The total field output by the fluxgate magnetometer is compensated in real time.
3.Technical index
number of flux gate axes | 3 (right-hand XYZ coordinate system) | Measuring range | ±100μT |
Internal noise: low noise | At 1Hz, ≤10pTrms/√Hz | preheating time | 15 minutes |
offset error | ±5nT in zero field | linear error | 0.0015%(least squares fit) |
Temperature coefficient of offset error | ±0.3nT/℃ | quadrature error | The axle error is less than±1° |
Digital output static noise level | <0.06 nT/1Hz | Dynamic flight compensation effect | 1-2nT(5Hz, typical) |
digital sampling rate | 10Hz-1Hz | Fluxgate aeromagnetic measurement system weight | 500g |
GPS accuracy | 2.5m/0.02m(RTK) | Wireless data transmission distance (through vision) | Maximum 20km |
