Multispectral system for UV, VIS and IR ranges
To measure the spatial distribution of the radiation intensity of lines in the upper atmosphere and ionosphere.
Description missing. Imaging fluxmeter for the UV radiation in the range 200-350 and the VIS lines at 630 nm [OI] and 427,8 nm [N2+]
Part of the instrument package carried by the Zond satellite of the 5-satellite Ionozonde constellation
Observation of the Earth's limb and Aurora occurrance as the satellite moves along its drifting LEO
300 km for UV viewing of the limb, 10 km for VIS imagery of the Earth's surface
Coverage / Cycle

Variable Relevance for measuring this variable Operational limitations Explanation
UV flux 1 - primary No specific limitation. Earth's limb and surface observed, wide dynamic range
UV sky image 2 - very high No specific limitation. Earth's limb observed, coarse spatial resolution
Aurora 1 - primary No specific limitation. Observed down to Earth's surface in UV and VIS
