Whats is the purpose of Radioteleprinter?: Transmitting and recieving messages between ships, ships and shore coomunication stations.
What is Simplex?: Single channel or frequency on which communications can be exchanged. Stations are capable of either transmitting or receiving but not at the same time.
What is full duplex?: Provides two channels or frequencies on which communication can be exchanged. Stations are capable of transmitting and receiving at the same time.
What is Half Duplex?: Provides ability to send and receive traffic on a single frequency, but not at the same time.

CMP key- allows the operator to compose a new message.
CONT CHAR key- allows operator to turn the control characterstics on or off the display readout of ASR teleprinter.
Bulk key- Used to transfer messages to storage on magnetic tape.
CAN Key- cancel or delete a message that is to be edited then compose a new one.
RPT Key- the table of contents report is printed RPT pressed with SHIFT a status report is generated.
RTV(Retrieve)Key- allows the operator to retrieve messages stored in the electronic circuits.
RLS(release)Key-release up to eight single sequentially numbered or randomly numbered message for transmission.
KYBD- Key places the teleprinter in character-by character status.

Passive- reflects radio signals back to earth.
What are the different types of orbit?: Synchronous orbit- satellite travels at the same speed as the earth's rotation.
Appears to hover motionless in the sky.
A non-synchronous is called a asynchronous.
Distance from the earth?: Apogee- is the point in the orbit the greatest distance from the center of the earth.
Perigee- is the point in the orbit nearest the center of the earth.
