靜電加速度計對重力衛(wèi)星平臺的要求分析

Key requirements for electrostatic accelerometer on gravity satellite platform

  • 摘要: 靜電加速度計是重力衛(wèi)星的核心有效載荷，其非保守力測量精度是地球重力場反演任務(wù)成功執(zhí)行的有效保證。文章分析了靜電加速度計的測量信號以及對重力衛(wèi)星平臺的指標(biāo)要求，重點指出滿足這些要求應(yīng)解決的關(guān)鍵技術(shù)，最后建議我國開展重力衛(wèi)星研究。

     

    Abstract: Electrostatic accelerometer is a key payload for gravity satellite, used for measuring the non-gravitational acceleration. Its detection accuracy eventually determines the success of the Earth’s gravity recovery mission. This paper discusses the observation signal of electrostatic accelerometer and its requirements on gravity satellite platform. Related key technologies are addressed. The significance of gravity satellite for our country is analyzed.
