摘要
为了适应高采样率、高分辨率、高精度的新型地磁仪器对磁偏角和磁倾角观测的需要,应用GPS测定了改造后的兰州地磁台的7个观测墩(一个临时观测墩)至2个方位标志的方位角,共取得了13个方位角参数,使兰州地磁台在地磁偏角测量或仪器验收比测中可供6套仪器同时观测,并可做到全天候观测。
In order to adapt to observational requirement of magnetic declination and magnetic inclination with the high sampling rate, high - resolution, high - precision. The azimuths of seven measurement pillars （ a temporary measurement pillar） and two azimuth marks are precisely measured by GPS in reconstructed Lanzhou station. 13 azimuth parameters are gained. After the measurements,6 sets of instruments can be used at the same time in all - weather in the magnetic declination measurements or acceptance testing of instruments.
