Space-borne infrared remote sensing specifically for the detection and characterization of fires has a long history in the DLR Institute of Optical Sensor Systems. In the year 2001, the first DLR experimental satellite, Bi-spectral Infrared Detection (BIRD), was launched after an intensive test period with cooled IR sensor systems on airborne systems. The main basis for the development of the FireBIRD mission with the two satellites, Technology Erprobungsträger No 1 (TET-1) and Bi-spectral-Infrared Optical System (BIROS), was the already space-proven sensor and satellite technology with successfully tested algorithms for fire detection and quantification in the form of the so-called fire radiation power (FRP). This paper summarizes the development principles for the IR sensor system of FireBIRD and the most critical design elements of the TET-1 and BIROS satellites, especially concerning the attitude control system-all very essential tools for high-resolution infrared fire monitoring. Key innovative tools necessary to increase the agility of small IR satellites are discussed.
在德国航空航天中心光学传感器系统研究所，专门用于火灾探测与特征分析的星载红外遥感技术有着悠久的历史。2001年，经过在机载系统上对冷却红外传感器系统的密集测试期后，德国航空航天中心的第一颗实验卫星——双光谱红外探测卫星（BIRD）发射升空。搭载两颗卫星——技术试验载体1号（TET - 1）和双光谱红外光学系统（BIROS）的火鸟任务（FireBIRD）的发展主要基于已在太空得到验证的传感器和卫星技术，以及已成功测试的用于火灾探测和以所谓的火灾辐射功率（FRP）形式进行量化的算法。本文总结了火鸟任务红外传感器系统的发展原则以及TET - 1和BIROS卫星最关键的设计要素，特别是关于姿态控制系统——这些都是高分辨率红外火灾监测非常重要的工具。文中还讨论了提高小型红外卫星敏捷性所需的关键创新工具。
