d is correct

please mark me as brainlist

Answer 2

Answer:

The correct answer is option D) All of the above

Explanation:

Satellite links are used to provide communications over very large distances (global coverage). This is achieved by using the satellite as a repeater. A ground station relays a signal up to the satellite at a frequency known as the uplink frequency. The satellite receives this signal and re-broadcasts it on a downlink frequency to another ground station. If digital communications signaling is used, the signal may be regenerated before it is re-transmitted to Earth. The analysis and design of satellite links are not unlike other links we have already studied in the course. There are particular details in evaluating certain components of the link budget that deserve particular attention: the characteristics of the satellite transponder, the fact that two frequencies (and hence two link budgets) are used, and the need to factor in the orbital geometry of the satellite to compute the free space loss.
