-Service Type: Fixed Satellite Service, Broadcast Satellite -Service, Mobile Satellite Service etc.

-Communication Requirements: Necessary signal bandwidth, modulation schemes, and overall system architecture.

-Baseband Quality: Required quality of the signal at the destination.

-System Capacity: Expected volume of traffic the Earth station will handle.

-Reliability: Required level of system reliability.

-Transmitter EIRP (Effective Isotropic Radiated Power): The EIRP of the transmitter impacts the strength of the signal sent to the satellite.

-Receiver Figure-of-Merit (G/T): The G/T ratio represents the efficiency of the Earth station's receive system in gathering weak signals while minimizing noise.

-System Noise and Interference: Mitigating system noise and interference is essential for maintaining signal integrity.

-Allowable Tracking Error
