摘要
航空重力仪是以飞机为载体探测区域和局部重力场的重力测量设备,航空重力测量是实现区域范围内高精度、高分辨率重力场信息获取的有效方法.为实现国产航空重力仪的完全自主可控,自主研制了新型全国产化航空重力仪(VGS系列),主要介绍了新型国产化航空重力仪的系统组成、工作原理及技术指标,并简述了机载重力测量试验系统集成和航空重力测量数据处理方法.经实际机载航空重力测量试验验证,新型国产化航空重力仪水平调整后的重复线内符合精度可达到0.4 mGal@0.01 Hz,比肩国际先进仪器精度水平,满足工程应用需求.
Abstract
Airborne gravimeter is a gravity measurement equipment that detects the area and local gravity field with the aircraft as the carrier, and airborne gravimetry is an effective method to achieve high-precision and high-resolution grav-ity field information acquisition in the region. In order to achieve the complete autonomy and controllability of domestic air-borne gravimeters, a new domestic airborne gravimeter( VGS series) is independently developed. The system composition, working principle and technical indicators of the new domestic airborne gravimeter are mainly introduced, and the integra-tion of airborne gravimetry test system and the data processing method of airborne gravimetry are briefly describes. The ac-tual airborne gravimetry test verifies that the accuracy of the repeating line after the level adjustment of the new domestic airborne gravimeter is 0. 4 mGal@0. 01 Hz, which is comparable to the international advanced instrument accuracy level and meets the needs of engineering applications.
