Question

Assume that a geosunchronous communications satellite is in ornit at the longitude of Kota. Your are at Kota and want to pick up its signals. In what direction should you point the axis of your parabolic antenna from vertical? The latitude of Kota is `30^(@)N`.

Answer 1

Correct Answer - `cot^(-1)(sqrt(3)-32/105)` to vertical

`(sin theta)/v=(sin(theta-30^(@)))/R`
`R/x=(sin thetacos30^(@)-cos thetasin30^(@))/(sin theta)`
`6400/42000=cos30^(@)-cot thetasin30^(@)`
`theta=cot^(-)[sqrt(3)-32/105]`
