Abstract
This paper expounds the advances in the development of a novel prototype UAV aero magnetic and radiometric integrated survey system developed by IGGE. The magnetometer consists of a CS-VL cesium vapour sensor and an AARC-510 real-time compensator and data logger. The gamma-ray spectrometer has 5 NaI(TI) crystal detectors. All the instruments were set up onboard a middle size UAV which can take off and land autonomously and fly for 10 hours with a 145kg payload at 180 km/h. A field trail survey of 3000 line-km was carried out at a exploration altitude of 120m AGL in 5 days to test the exploration performance of the system. Four flights were accomplished during the night. The survey data quality are competitive over traditional airborne survey system and meets the CGS survey specifications. However, some more optimization research will be required to improve the reliability and safety, simplify the operation, lower the costs, and make it a commercially usable system.
