Out with the Old, In with the New
Single, older-generation satellites are becoming obsolete, while smaller, lower-orbiting constellations of satellites designed for earth observation and satellite communications (satcom) are becoming the norm. Hundreds of these satellites can be launched by a single rocket, creating interconnected constellations of satellites for earth observation or communications.
Essential to the operation of these satellites are spectral filters, which separate optical signals from background noise. Iridian Spectral Technologies breaks down the role of spectral filters and how to design with spectral filters in mind.
To learn more, read Iridian’s article, entitled “Designing Optical Filters for Earth Observation and Satcom.”
