First aircraft test results of a compact, low cost hyperspectral imager for earth observation from space
2017
In recent years TNO has investigated and developed different innovative opto-mechanical designs to
realize advanced spectrometers for space applications in a more compact and cost-effective manner.
This offers multiple advantages: a compact instrument can be flown on a much smaller platform or as
add-on on a larger platform; a low-cost instrument opens up the possibility to fly multiple instruments
in a satellite constellation, improving both global coverage and temporal sampling (e.g. multiple
overpasses per day to study diurnal processes); in this way a constellation of low-cost instruments
may provide added value to the larger scientific and operational satellite missions (e.g. the
Copernicus Sentinel missions); a small, lightweight spectrometer can easily be mounted on a small
aircraft or high-altitude UAV (offering high spatial resolution).
