Radio waves are used to carry satellite signals. These waves travel at 300,000 km/s (the speed of light). This means that a signal sent to a satellite 38,000 km away takes 0.13 s to reach the satellite and another 0.13 s for the return signal to be received back on Earth.
Read moreWhat are transponders in satellite systems?
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 the bandwidth of one Starlink satellite?
Unlike other satellite internet providers, Starlink’s LEO satellites promise to offer low-latency broadband speeds regardless of where you are. While Starlink was first boasting speeds of 1 Gbps, it’s since upped that target to 10 Gbps .
Read moreWhat is the bandwidth of Ku band?
Ku band satellite has uplink frequency in the range from 14000 to 14500 MHz and downlink in the range from 11700 to 12200 MHz. Figure-2 depicts total 24 transponders with each utilizing 36 MHz from total bandwidth of 500 MHz .
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.
