Abstract
This article is dedicated to analysis of multi-level magnetic survey’s data conducted on one of the test areas of gas pipeline network. The main task of the research is development of optimal technique and evaluate the practical possibility of low-altitude aerial magnetic survey with UAV when solving the problems of searching and localization of various types of iron-containing technogenic linear objects. Two types of measurements were performed: ground magnetic survey at a height of 2 meters (the height of the sensor) above the ground and aeromagnetic survey using a quadrocopter carrier at heights of 5 meters and 20 meters. Aeromagnetic survey was carried out according to the new technology of low-altitude surveys using the GEOSCAN 401 aeromagnetic complex, based on a quadrocopter and a quantum magnetometer. According to the research results, all existing underground communications (pipelines, wells) were identified, their depth was determined, and optimal parameters of magnetic survey were developed for searching of underground industrial object.
