Recently, GTK was invited to bring a new generation of drone aeromagnetic measurement systems to a Kuangqu in the north to complete a live application demonstration of the multi-rotor drone aeromagnetic system. The actual measurement results show that the aeromagnetic acquisition data of the GTK drone is highly consistent with the existing ground magnetic measurement data in the area. At the same time, the comprehensive performance of the company's self-developed rubidium atomic optical pump magnetometer is significantly better than that of imported similar equipment. With excellent technical strength, customers are highly recognized.


This on-site demonstration lasted three days. The Jiatoco technical team successfully completed the collection of high-precision magnetic field data in the designated measurement area relying on the company's independently developed rubidium optical pump drone aeromagnetic system. The team cross-compared and analyzed the measured data of the two types of optically pumped aeromagnetic systems with the ground magnetic survey results carried out by customers in the early stage. The results showed that the abnormal shapes, amplitude characteristics and geological structure feedback of the two were highly consistent, and the data complied with the industry's general standards.
This actual measurement fully verified the operating stability and data reliability of the GTK drone aeromagnetic system in complex terrain environments of the Kuangqu. Compared with traditional ground magnetic survey methods, the system has higher operating efficiency and lower comprehensive cost., providing high-quality and efficient domestically produced technical solutions for the subsequent refined geological exploration work in the Kuangqu.


The core highlights of this demonstration are outstanding. In order to intuitively compare the performance differences of equipment, the technical team adopted a same-aircraft mounted test mode. On the same drone platform, they were equipped with imported well-known brands rubidium atomic optical pump magnetometer and Jiateco's self-developed rubidium atomic optical pump magnetometer. Synchronized flight operation to achieve real performance comparison under the same environment and same working conditions.
Through the comparative analysis of the raw data of the survey line section and the plane equivalent results, it is known that the data consistency of the two devices is excellent. More core advantages are that many key performance indicators of the self-developed rubidium atomic optical pump magnetometer comprehensively exceed imported mainstream equipment: the equipment noise level is as low as ≤0.005nT, which is 4 times higher than the performance of imported products; the probe 360-degree horizontal rotation direction error ≤0.9nT, the accuracy is increased by 3 times; the dynamic noise level is as low as 0.006nT, which is increased by 10 times. The overall signal acquisition accuracy and stability are far ahead of imported similar products.


The actual measurement results fully confirm GTK's independent research and development and technological innovation capabilities in the field of core sensors of atomic optical pump magnetometers. The company's mass-produced version of the atomic magnetometer successfully broke through technical barriers and supply constraints of imported equipment, completely solved the "stuck neck" problem of core components in the industry, and provided a solid technical foundation for the full-process localization and full-chain autonomy in the field of aeromagnetic exploration of atomic optical pump magnetometer drones. The implementation of controllable solutions has laid a solid technical foundation.
The complete success of this on-site demonstration in a Kuangqu mining area in the north marks that the aeromagnetic technology of GTK's fully self-developed drone has matured and has officially entered a new stage of large-scale and commercial application. In the future, the company will continue to deepen the field of aerogophysical exploration, continue to iteratively optimize core technologies and intelligent equipment, and use high-precision and high-stability localized geophysical exploration technology and high-quality services to help the high-quality development of the domestic mineral exploration industry and promote my country's aerospace geophysical exploration equipment localization and upgrading process.
