A satellite or spacecraft in low Earth orbit, when in eclipse and not illuminated by sunlight, represents a low-bandwidth datastream through modulation of a source of uncollimated light, such as a set of light emitting diodes. Transmission modes include generating patterns in the color, intensity or polarization of a light source, or precise timing control of a strobe signal.

The invention provides a high-spectrum remote-sensing mineral content quantitative inversion method, based on spectrum linear resolution. Before linear resolution, the end-member spectrum and high-spectrum data are subjected to continuum removing treatment to eliminate the effect of the landform, solar illumination on the spectrum; during linear resolution, the end-members with wave band of 1 are added into the end-member spectrum for representing the mineral end-members without obvious absorptive character in all the spectrum decomposition wave-band range and the end-member spectrum without absorptive character is subjected to continuum removing treatment and then represented using the end-members with wave band of 1; after linear resolution, a modifier formula is brought forward direct towards the effect of the non-linear mixture of the mineral spectrum on the mineral content inversion result, the formula corrects the mineral content subjected to spectrum linear resolution and inversion to make the inversed mineral content more closed to the accurate content. The mineral mixed test shows that: the correction formula can be reduced the error of the mineral content inversion. The test data shows that: the mineral content inversion average error which is not corrected is 29.8% and after being corrected, the average error is reduced to 4.5%.
