A transponder is a device that responds to a signal by emitting a separate signal. The word combines the words “transmitter” and “responder.”
A flight transponder is an automated transceiver in an aircraft that emits a coded identifying signal in response to an interrogating received signal for radio frequency identification or air navigation.
A satellite transponder in a communications satellite receives signals on a variety of uplink frequencies, typically from a satellite ground station; the transponder amplifies the signals and retransmits them to receivers on Earth, frequently without altering the content of the received signal or signals.
The Global Defense Transponders market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
A BOOST FOR SPACE COMMUNICATIONS SATELLITES.In accordance with a deal with the German Ministry of Defense, Astrium will provide COMSATBw-2 and SES ASTRA 3B for the Luxembourg-based operator SES ASTRA, respectively.
Leading space communications companies and manufacturers’ selection of Arianespace is unequivocal evidence of the company’s superiority in launch services on a global scale. The Arianespace launch system still sets the bar for launch systems because of its dependability and availability.
The only commercial satellite launcher currently available that can launch two payloads at once is Ariane 5.
Arianespace and SES have a remarkable working relationship that has grown over the past few years. The SES group (Euronext Paris and Luxembourg Bourse: SESG) will use ASTRA 3B, its 33rd satellite, as their launch vehicle of choice from Europe. SES More than 125 million households are served by ASTRA’s premier direct-to-home TV transmission system in Europe through cable and DTH networks.
Using a Eurostar E 3000 platform, Astrium constructed the ASTRA 3B satellite, which will launch weighing about 5,500 kg.
ASTRA 3B will be located at 23.5 degrees East and equipped with 60 active Ku-band transponders and four active Ka-band transponders. It boasts a design life and will supply high-power broadcast services throughout all of Europe.
Two military communications satellites, COMSATBw-1 and COMSATBw-2, built by Astrium and supplied to the German Ministry of Defense as part of a satellite communications system, were launched by Arianespace. Arianespace launched COMSATBw-1, the first satellite in this family, into orbit. The 34th military payload launched by Arianespace will be COMSATBw-2.
