Abstract

Satellite platform microvibration is a common phenomenon in earth observation satellite orbits that directly affects the imaging quality and accuracy of surveying and mapping. With the continuous improvement in the spatial resolution, the influence of satellite platform microvibration on image geometric accuracy is becoming increasingly significant. High-precision microvibration detection and compensation are key technologies for eliminating image distortion and location deviation caused by satellite platform microvibration. In this paper, the microvibration detection methods of different satellite platforms are summarized, and the verification and analysis are performed on the data downloaded from the Resource-3 satellite (ZY-3) platform, to provide technical support for subsequent refined processing of satellite attitude.

摘要

卫星平台微振动是地球观测卫星轨道中的一种常见现象，直接影响测绘的成像质量和精度。随着空间分辨率的不断提高，卫星平台微振动对图像几何精度的影响越来越显著。高精度微振动检测和补偿是消除卫星平台微振动引起的图像变形和位置偏差的关键技术。本文总结了不同卫星平台的微振动检测方法，并对资源三号卫星（ZY-3）平台下载的数据进行了验证和分析，为后续卫星姿态的精细处理提供技术支持。
