Our High Data Rate X-Band Transmitter, XONOS, is dedicated to mini/micro-satellites. It especially meets the expressed demand from satellite operator to implement high data rate transmission between satellite and ground segment, enabling much more data volume downlink. XONOS is a latest state-of-the-art qualified COTS based design. Such design is perfectly adapted to New Space programs, where cost effectiveness, performances and reliability are success key factors.

XONOS implement advanced CCSDS encoding techniques and modulation schemes (8PSK-4D-TCM, DVB-S2, …) to achieve very high data rates in X-Band 375 MHz bandwidth signal.

One key feature is the capability to change and adapt the transmission parameters dynamically and in-flight. The transmitter embeds a DC/DC converter with galvanic isolation as required for Mini/Micro satellite integration. It also authorizes data and control interface redundancy implementation to maximize the in-flight service availability.
