What is the main function of a communications satellite?

• To facilitate high-speed telephone signals

• To provide continuous coverage for satellite phone systems

• To study the properties of radio wave distribution throughout the ionosphere

• To relay and amplify radio telecommunication signals

What is the advantage of a geostationary orbit for communications satellites?

• It requires fewer satellites for uninterrupted connectivity

• It appears motionless in the sky, allowing ground antennas to be fixed at a specific location

• It provides a larger coverage area than low Earth orbit satellites

• It allows for faster communication with reduced latency

What is the primary purpose of a low Earth orbit (LEO) satellite?

• To provide continuous coverage for satellite phone systems

• To connect directly to a constellation of geostationary satellites

• To facilitate high-speed telephone signals

• To relay and amplify radio telecommunication signals

What is the main difference between medium Earth orbit (MEO) and low Earth orbit (LEO) satellites?

• MEO satellites have a longer time delay and weaker signal than LEO satellites

• MEO satellites have a larger coverage area than LEO satellites

• MEO satellites have a longer duration of visibility and wider footprint than LEO satellites

• MEO satellites require fewer satellites for uninterrupted connectivity than LEO satellites

What is the purpose of the Molniya orbit for satellites?

• To guarantee good elevation over selected positions during the northern portion of the orbit

• To maintain a stationary distance from the Earth and provide uninterrupted coverage

• To provide continuous coverage for satellite phone systems in extreme latitudes

• To operate above the equator and appear lower on the horizon as the receiver gets farther from the equator

What is the function of the communication payload in a communications satellite?

• To power the satellite systems using solar cells and batteries

• To provide a Lunar Internet for cis-lunar spacecraft and Installations

• To maintain communications with ground control stations

• To relay and amplify radio telecommunication signals

What is the primary application for communication satellites in remote islands and regions with rare landline telecommunications?

• Providing continuous coverage for satellite phone systems

• Connecting directly to a constellation of geostationary satellites

• Facilitating high-speed telephone signals

• Relaying and amplifying radio telecommunication signals

What is the main market for communication satellites in North America?

• Direct broadcast satellite (DBS)

• Satellite phone systems

• Remote islands and regions with rare landline telecommunications

• Fixed Service Satellite (FSS)
