针对国内对于高精度海空重力仪的迫切需求，自主研制了GIPS-1AM高精度惯性稳定平台式海空重力仪样机。突破了高精度重力敏感器设计、高精密温度控制、总体设计和自标定等关键技术问题，完成了样机的设计、调试和试验测试。试验测试结果表明，样机温控精度优于001℃，静态长时间工作稳定性、不同楼层重力测试精度均优于1mGal（1σ）。可满足大地测量学、地球物理学、地球动力学、海洋科学、资源勘探、空间科学以及现代军事等基础前沿领域的重力测量需求。

Abstract:

To meet the urgent needs of high-precision airborne/marine gravimeter in our country, the GIPS-1AM airborne/marine gravimeter based on the high precision inertial stabilized platform is developed independently. Many key technologies are breakthrough, such as the high accuracy gravity sensor designing, high precision temperature controlling, overall designing and self-aligning and so on. The prototype is designed, produced and tested. The experiment results show that the precision of the temperature is 001℃. Furthermore, the long duration static stability, the different floors’ gravity measurement accuracy are both better than 1mGal（1σ）. The product can meet the demand of the forefront academic such as geodesy, geophysics, geodynamics, ocean science, resource exploration, space science and modern military.
