| 摘 要： | 首先推导了当采用相位时序差分法时利用双差观测量确定载体加速度的数学模型，理论上分析了加速度的确定精度。然后应用CHAGS的试验数据，分析出静态测量和动态测量时加速度矢量的确定精度可以达到亚毫伽级，与理论上的分析一致。可见，完全能够满足航空矢量重力测量的精度要求。 |

| Abstract: | Firstly the mathematical model of acceleration vector by double-difference is established using the phase difference method, and the accuracy is analyzed in theory. Then the precision of the determination of the acceleration vector under stable and kinetic conditions is analyzed respectively based on CHAGS observation, and the accuracy is second mGal, which is the same as the precision in theory and absolutely satisfies the demand of the airborne vector gravimetry. |
| Keywords: | airborne vector gravimetry phase difference method acceleration vector double-difference |
