Instrument details
Acronym LETITsIYA-Camera
Full name Multispectral system for UV, VIS and IR ranges
Purpose To measure the spatial distribution of the radiation intensity of lines in the upper atmosphere and ionosphere.
Short description 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+]
Background Part of the instrument package carried by the Zond satellite of the 5-satellite Ionozonde constellation
Scanning Technique Observation of the Earth's limb and Aurora occurrance as the satellite moves along its drifting LEO
Resolution 300 km for UV viewing of the limb, 10 km for VIS imagery of the Earth's surface
Coverage / Cycle Full magnetosphere and ionosphere. Sampling at 1 s intervals
Mass Power Data Rate
