NanoCom Link SX

Based on the flight proven series of GomSpace Software Defined Radios (SDR), NanoCom Link SX combines the features of NanoCom Link S and X in an ultra-compact flexible solution, ideal for supporting Remote Sensing, Earth Observation and SIGINT missions as well as TMTC applications.

Radio link rates up to 7.5Mbps in S-Band (TX/RX) and up to 225Mbps X band (TX) are possible simultaneously. NanoCom Link SX also features an integrated front end and antenna  in both S and X band which can be optimally placed in the satellite, independent to the modem/transmitter location, without worrying about signal loss. 

Voice and streaming applications are particularly well catered for due to low latency package transfer capabilities. NanoCom Link SX’s power, frequency and modulation/ coding can be configured and controlled in orbit to ensure optimum data throughput.

Mission flexibility is enhanced by on-board Store and Forward capability with up to 120GB of data storage available for transferring payload data by transferring payload data by high-speed space-wire or low-speed RS-422  interfaces and TCP/IP protocols. CAN or RS422 and CSP are provided for configuration and control.  Support for flight scheduled data-transmission is provided well as S-Band Bi-directional file copy with RSYNC or even a hybrid S-Band (RX) and X-Band (TX) link.   TMTC security is enhanced with the possibility of a CSP connection using SSH, while also supporting simultaneous payload data downloads 

CCSDS 131.0-B-4 and DVB-S2 MODCODs (ETSI EN 302 307-1 V1.4.1) compliant, NanoCom Link SX has also been verified with commercial off-the-self ground station equipment   and is compatible with major commercial ground station service providers. 

GomSpace’s  NanoCom Link Connect software for Ground Systems also supports Nanocom Link SX , facilitating a low cost ground station segment.   For orbits passing near NASA’s Deep Space Network ground stations, an optional X-band DSN filter kit is available if needed.
