About
The Antenna-feeder Device (AFD) Ionosphere is a communication component specifically designed for spacecraft applications. Its primary purpose is to facilitate the transmission of radio signals from the spacecraft’s onboard transmitter to ground receiving points. Additionally, it is used for emitting coherent radio signals from the Mayak airborne transmitter of the spacecraft into the lower hemisphere (nadir). The product was released in 2010 and has a guaranteed service life of 8 years. The estimated production and delivery time is 6 months. While it does not have flight qualification, it has been delivered for the Ionosphere spacecraft, indicating its intended use in space missions. The manufacturer offers the possibility to adapt the product to customer requirements. The AFD Ionosphere operates across multiple frequency ranges, including 137 MHz, 150 MHz, and 400 MHz, and supports communication angles from 0 to 64 degrees. It has a weight of 4 kg and is available in specific configurations for each frequency: AFD 137 MHz, AFD 150 MHz, and AFD 400 MHz.
