1. The problem statement, all variables and given/known data a satellite is orbiting the earth in a near-polar orbit. it's orbital height is 500km. the satellite carries a nadir-viewing push-broom scanning imaging instrument with 4 spectral bands. for each spectral band, the detector array consists of 1024 detector elements. the width of each detector element is 15 μm. focal length of telescope is 10m. a) find the orbital period. i got 6044s using the kepler eq. b) at 3:10 UTC, the same satellite crosses the equator at longitude 105 deg E as it travels from north to south. i) when wil the satellite next cross the equator in the same north to south direction. ii) what wil be the longitude of the equator crossing point? for part i), is it adding the orbital period is 6044s to 3:10? for part ii), i found out that the earth rotates 0.25 deg every min, since orbital period is 6044s=101min, the satellite will move 25.25 deg further, so is it 105deg +25.25 deg=130.3deg E? c) what is the ground pixel of the imaging instru of this satellite? i made use of this eq: ground pixel width W= (detector element width b x orbital ht) / focal length, which i got 1.2m d) the imaging sensor is turned on for 20s to acquire an image of the earth surface, what is the width and length of the area on the eart surface imaged by the satellite? i dont quite understand the qn, is it sth to do with the swath width? how do i go about looking for the swath width? thanks in advance!
