van Brug, H. (author), Visser, H. (author)This paper describes one of the issues that are facing the remote sensing community in the not so far future; scientists ask for certain requirement that cannot be fulfilled either due to cost issues or technological issues. The paper starts with giving a short and quick historical overview of the development of spectrometer based remote sensing...conference paper 2016

van der Wal, L.F. (author), de Goeij, B.T.G. (author), Jansen, R. (author), Oosterling, J.A.J. (author), Snijders, B. (author)The market for nano-and microsatellites is developing rapidly. There is a strong focus on 2D imaging of the Earth's surface, with limited possibilities to obtain spectral information. More demanding applications, such as monitoring trace gases, aerosols or water quality still require advanced imaging instruments, which are large, heavy and...conference paper 2016
