Design of a satellite beacon receiver for ionospheric remote sensing
In today's world of communication, satellite communication plays an important role. The communication between ground stations and satellites orbiting the earth at high altitudes needs to be increasingly accurate to handle today's data flow requirements. The study of the ionosphere allows engineers …
