The ALTIUS instrument, onboard a Proba satellite, will observe the Earth atmosphere’s bright limb. The atmosphere observations will take place in different small wavelength areas in the UV-VIS-NIR spectral area (3 channels). The selection of the spectral bands is based on the use of AOTFs (Acousto-Optical Tunable Filters).
In 2008 the phase A of the study of the project was executed. The phase B started in 2009.
The development will start in the course of 2017, and the payload should be ready for launch by 2021.
Status: Pre-development phase
Field: Earth observation
