XONOS – X-Band High-Data-Rate Transmitter

XONOS is the latest generation of Syrlinks’ High-Data-Rate Transmitter line, dedicated to mini/micro-satellites. It addresses satellite operators’ demand for high data rate transmission between satellite and ground segment, enabling much greater data volume downlink. XONOS is built on a state-of-the-art qualified COTS-based design, well suited to New-Space programs where cost effectiveness, performance, and reliability are key success factors. It implements advanced CCSDS encoding techniques and modulation schemes (8PSK-4D-TCM, DVB-S2, etc.) to achieve useful data rates greater than 1 Gbps within a 375 MHz bandwidth signal in X-Band. A key feature is the capability to change and adapt transmission parameters dynamically and in-flight. The transmitter embeds a DC/DC converter with galvanic isolation as required for mini/micro satellite integration, and it also allows for data and control interface redundancy implementation to maximize in-flight service availability. The XONOS design inherits from Syrlinks’ skills and flight heritage experience acquired over more than 20 years in RF communication design for space. It belongs to the Telecom Subsystem category, is classified as a Transmitter component type, sized for the SmallSat form factor, and is currently listed as In Production.
