中文摘要 | 福爾摩沙衛星五號(以下簡稱福衛五號)搭載一個黑白2 米,彩色4 米的遙測影像儀,是我國第一顆完全自主發展的高解析度遙測衛星。為了提升福衛五號取像的效率,增加一個所謂「靈活取像」(Smart Agility Imaging Mode)的非同步取像模式,使得福衛五號能沿地面特定方向以「邊轉邊照」方式取像。為了驗證「靈活取像」的可行性,太空中心依據遙測衛星取像程序完成系統的驗證,首先是非同步取像衛星姿態演算法的發展,接著是非同步取像衛星姿控演算法的開發,最後則是非同步取像模擬影像的展示。本文主要目的是介紹太空中心在非同步取像衛星姿態計算及其衛星影像模擬製作的發展。 |
英文摘要 | Scheduled to be launched in 2015, FORMOSAT-5, equipped with 2 m panchromatic and 4 m multi-spectral imaging sensor, is the Taiwan first self-reliant remote sensing satellite. To increase the efficiency for FORMOSAT-5 to acquire images on the ground, a function, so called “smart agility” or asynchronous imaging, is designed in FORMOSAT-5. With the function of asynchronous imaging, FORMOSAT-5 can rotate its body when it acquires images along a given specific direction on the ground. To verify the feasibility of smart agility mode for FORMOSAT-5, NSPO conducts a series of verification processes based on the sequence of satellite imaging. Firstly, the satellite attitude algorithm for asynchronous imaging mode was derived. Secondly, satellite on-board AOCS algorithm was developed. Lastly, simulated image was demonstrated. The aim of this article is to introduce some research results for asynchronous imaging in NSPO, including algorithms to calculate satellite attitude in asynchronous imaging mode, and asynchronous images simulation. |
