METHOD DETERMINING EARTH ALBEDO Russian patent published in 2009 - IPC G01N21/55 

FIELD: physics; astronautics.

SUBSTANCE: method includes consecutive arrangement of equipment sensitive to registered radiation not less than in two spatial standings and determination of the moments of the Sun location in a zenithal field over spacecraft (SC) supplied with two or more solar batteries (SB) over catopter. At the moment of passage of under-sun point of the orbit pass at the Sun location in zenithal field over the SC the first SB is turned into position, corresponding to normal line combination to its effective area with direction on the Sun. Another SB is turned in standing corresponding to combination of normal line to its effective area with counter-sun direction. Measure values of current from every SB. Earth albedo value is determined under the formula: A=(KI₂-K2I₁)/(I₁KK₁I₂) where I_{1, 2} - measured values of current from the SB, normal lines to which effective areas are combined, accordingly, with direction on the Sun and with counter-sun direction; K - the given coefficient of target power of effective area of the first SB concerning target power of an effective area of the second SB; K_{1, 2}-set coefficients of target power of back surface, accordingly, the first and the second SB concerning target power of effective area corresponding SB.

EFFECT: determination simplification of Earth albedo.
