Angular measurements - CEE Cornell

If a polar orbiting satellite flying at an altitude of 800 km had an imaging system that was capable of the same angular resolution: [1]What would be the . length. of a single pixel on the earth immediately below the satellite (viewing at nadir, or a viewing angle of 0()? Δx = altitude x (IFOV (in radians) = 8 x 105 m x 4.12x10-8 rad = 3.3*10-2 m ................
