| 内容記述 | We have begun the development of a three-axis aeromagnetic survey instrument for use on board helicopters and multicopters. It consists of sensors, loggers, and communication devices. In the present paper, we describe its components in detail. Tests were performed to measure the altitude difference between a barometric sensor to be placed on board a helicopter or multicopter and a sensor to be placed on the ground during the survey to determine the sensor accuracy. The accuracy of the horizontal coordinates was also evaluated using GPS devices attached to barometric sensors. The tests were performed under two conditions: two pairs of barometric and temperature sensors were fixed at almost the same position where a strong GPS signal was received, and the two pairs were separated by a known altitude difference with one pair set at a position where the GPS signal was weak. The results showed that regardless of the GPS signal strength, the altitude difference estimated using the barometric and temperature sensors exhibited an error of up to about 2.4 m while for the GPS device the error was 6.5 m for a strong signal and about 59 m for a weak signal. In addition, the error in the horizontal coordinates was about 3 m for a strong GPS signal. The results of the present study therefore indicate that the use of barometric and temperature sensors is effective for accurately determining the altitude of a magnetic sensor for aeromagnetic surveys, particularly when three-axis magnetic sensors are used. |
