Y12 aviation physical exploration comprehensive measurement system consists of HDY-402 tri-frequency aviation electromagnetic instrument, GB-4A aviation helium light pump magnetometer, GR-820 multi-channel gamma energy spectrometer, including digital inclusion monitoring, radio altitude, barometric altitude, temperature and other auxiliary measurement equipment. The system is based on the Y12 aircraft platform, which is suitable for ultra-low altitude operation. The average flight altitude in plain area is generally less than 50 meters, and the flight altitude in hilly area is generally less than 70 meters, and the average measurement efficiency is about 120 km/hour. The Beidou clock ensures strict time-frequency unification under high dynamics of each collector, which improves the system efficiency and collection accuracy.
