摘要: For a variety of applications, magnetic data is collected from airborne platforms. Normally, this with sensors that measure the total field or amplitude vector data. New generations optically pumped are extremely sensitive their sensitivity quoted often in picoteslas. At present, some new instrumentation also attempting to high accuracy Despite modern and acquisition systems, noise flying platform still one limiting factors obtaining highly accurate The aircraft helicopter itself emanates signals. These signals due number including induced fields magnetically susceptible materials permanent on platforms as well both electromagnetic generated either by electrical systems moving parts such rotors. This subject paper problems techniques related removing effects attempts study use simulated
