Paper Abstract

The Platform for the Observation of the Earth and for in-orbit Technology Experiments (POETE) mission concept has been developed to help overcome the scientific and socio-economic issues associated with forest fires. The proposed mission is based on a series of two highly autonomous and agile microsatellites, allowing for 3 to 7 visits per day. Each satellite payload includs a VIS-NIR instrument and a MWIR-TIR instrument. The two instruments combined provide for 6 spectral channels spanning from the visible to the thermal infrared for fire monitoring, retrieval of quantitative fire parameters (such as effective fire temperature, area and radiative energy release), and land surface temperature measurement. The MWIR-TIR instrument concept is a pushbroom scanner filter radiometer with on-board radiometric calibration capabilities. Its all-reflective three-mirror input optics delivers a 400-m GSD at an altitude of 700 km, relaying the scene signal to detectors based on INO's microbolometer technology for detection in four spectral channels centered at 3.8 μm, 8.8 μm, 10.5 μm and 12.0 μm. This paper presents an overview of the key mission requirements and derived sensor level requirements. A description of the conceptual design of the MWIR-TIR payload of POETE is given along with estimates of key performance parameters.
