the SABER instrument aboard the TIMED satellite orbits the earth in a sun-synchronous polar orbit 625 Km above the earth. each of the 10 SABER focal plan detectors is 0.14mm high by 2.0mm wide. the focal plane array is 4.882*4.882mm in size with a field of view of 1,4*1.4. assume that the mean radius of earth is 6.368000 Km. what is the footprint of the entire focal plane array at the tangent point 100Km above the earth? what the footprint of each individual detector at that same location?
