A communications satellite’s transponder is the series of interconnected units that form a communications channel between the receiving and the transmitting antennas. It is mainly used in satellite communication to transfer the received signals .
Read moreHow many transponders does a satellite have?
A typical satellite has up to 32 K u-band or 24 C-band transponders, or more for K u/C hybrid satellites . Typical transponders each have a bandwidth between 27 and 50 MHz.
Read moreHow many channels does a transponder have?
Each satellite transponder can carry 2 channels of regular (analog) TV programs, or 6 channels of digital TV programs .
Read moreWhat does transponder stand for?
A transponder (short for transmitter-responder and sometimes abbreviated to XPDR, XPNDR, TPDR or TP) is an electronic device that produces a response when it receives a radio-frequency interrogation.
Read moreHow many transponders are in a satellite?
Early Bird had just one transponder capable of sending just one TV channel. The Boeing 702 series of satellites, in contrast, can have more than 100 transponders , and with the use of digital compression technology each transponder can have up to 16 channels, providing more than 1,600 TV channels through one satellite.
Read moreWhat does transponder in satellite do?
The term “satellite transponder” refers collectively to a transmitter-receiver subsystem on board the satellite that processes, amplifies and retransmits a range of frequencies (the transponder bandwidth) to another location/terminal/antenna on the earth .
Read moreHow does a transponder work?
A transponder will send an identifying coded signal in response to a transmitted interrogation from a ground-based radar station . An air traffic controller can then view the identified blip on a screen and know who it is and provide direction to the flight crews maintaining adequate separation with other blips.
