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 much bandwidth accommodate for each transponder in C band?
The bandwidth allocated for C band service is 500 MHz , and this is divided into sub bands, one for each transponder. A typical transponder bandwidth is 36 MHz, and allowing for a 4-MHz guard band between transponders, 12 such transponders can be accommodated in the 500-MHz bandwidth.
Read moreWhat is transponder frequency?
In a transponder the transmit carrier frequency is derived from the received signal . The frequency linkage allows an interrogating ground station to recover the Doppler shift and thus infer range and speed from a communication signal without allocating power to a separate ranging signal.
Read moreWhat is bandwidth satellite communication?
The amount of data that can be received, processed, and transmitted by a satellite are commonly stated in megabits per second (one million bits of data per second) or gigabits per second (one billion bits per second).
Read moreWhat is the average frequency range of satellite signal?
Modern systems signals are relayed from a communications satellite on the X band (8–12 GHz) or K u band (12–18 GHz) frequencies requiring only a small dish less than a meter in diameter. The first satellite TV systems were an obsolete type now known as television receive-only.
Read moreWhat frequency bands are used in satellite communication?
Which are the frequency bands used for satellite communication? The major frequency bands used for satellite communication in India are S-band, C-band, Upper Extended C band, Ku band and Ka band . The INSAT/GSAT satellites carry transponders in these bands. 4.

Internet via satellite phone Bandwidth varies from about 2400 bit/s for Iridium network satellites and ACeS based phones to 15 kbit/s upstream and 60 kbit/s downstream for Thuraya handsets .
