| 摘 要： | 目前，成熟应用的航空重力测量系统主要为两轴阻尼平台，例如LaCoste&Romberg海空重力仪，以及三轴惯导平台，例如GT-1A航空重力仪和AirGrav航空重力仪。虽然捷联式航空重力仪研制及应用尚未成熟，但通过本文对自主研制的激光捷联式与速率方位平台式航空重力仪进行的车载重力测量试验表明，两种类型重力仪样机获得的自由空间重力异常精度相当。

| Abstract: | To date, operational airborne gravimetry systems use either a damped two-axis stable platform system sucn as LaCoste and Romberg sea-air gravimeter, or three-axis platform inertial navigation system such as GT-1A and AirGrav airborne gravimeter. Although the development and application of the airbore gravimeter based on the strapdown inertial navigation system is not well done now, the prototype developed based on the laser strapdown inertial navigation system have shown comparable accuracies of the free-air gravity anomaly with the prototype based on the rate azimuth platform through the ground-vehicle tests. |
