NanoCom Link S

Based on the flight proven series of GomSpace Software Defined Radios (SDR),  NanoCom Link S allows for radio link rates up to 7.5Mbps and features an integrated front end and S band antenna which can be optimally placed in the satellite, independent to the modem/transmitter location, without worrying about signal loss.    

This full duplex S-band link is an extremely attractive alternative for users who are unable to obtain an X-band license.  Voice and streaming applications are particularly well catered for due to low latency package transfer capabilities. NanoCom Link S’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 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 Bi-directional file copy with RSYNC.   Enhanced TMTC security is provided by supporting a CSP connection using SSH, while also supporting simultaneous payload data downloads. 


CCSDS 131.0-B-4 compliant, 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 S, facilitating a low cost ground station segment.
