In 2006 the Italian and the Canadian Space Agencies started a collaboration to evaluate the feasibility of the Joint Hyperspectral Mission (JHM), a new mission for Earth Observation devoted to environmental applications. JHM was designed to operate with a 30 m resolution hyperspectral sensor able to collect 210 narrow spectral bands in the range of 400-2500 nm. This paper presents a study carried on for the Italian Space Agency during Phase A, aimed to suggest an optimal spectral setup for the land-cover key application. Just referring to the mapping of forest species, results on simulated JHM data suggested that an optimal configuration can be obtained using a 50 nm bandwidth

“…2: Sample Mission application for TIR EO micro-satellite constellations [12] The THEMA study provides a good starting point because it represents a recent and thorough analysis of user requirements and the general acceptance by the TIR data users. Of special interest is forest fire detection, which, if used in conjunction with on-board detection algorithms and autonomous ground user data transfer, would fill an important niche in the global fire detection community.…”

A new class of thermal infrared (TIR) Earth Observation (EO) data will become available with the flight of miniature TIR EO instruments in a multiple micro-satellite constellation. This data set will provide a unique service for those wishing to analyse trends or rapidly detect anomalous changes in the TIR characteristics of the Earth's surface or atmosphere (e.g. fire detection). Following a preliminary study of potential mission applications, uncooled commercialoff-the-shelf (COTS) technology was selected to form the basis of a low-cost, compact instrument capable of complementing existing visible and near IR EO capabilities on a sub-100kg Surrey micro-satellite. The preliminary 2-3 kg instrument concept has been designed to yield a 325 m ground sample distance over a 200 km swath width from a constellation altitude of 700 km. The radiometric performance, enhanced with time-delayed integration (TDI), is expected to yield a NETD less than 0.5 K for a 300 K ground scene. Fabrication and characterization of a space-ready instrument is planned for late 2004.
