The NANOlink(-S)-boost is a highly miniaturized full-duplex TM/TC satellite communication subsystem, equipped with an additional efficient integrated amplifier, and an optional built-in encryption system that provides a high level of security between the satellite and the ground station (GS). Several intelligent built-in functions enable the NANOlink(-S)-boost to operate as a fully autonomous system, facilitating the streamlined acquisition of satellite diagnostic data. The optional security features (-S) utilize the CCSDS Space Data Link Security protocol. Additionally, the NANOlink(-S)-boost supports the symmetric AES-GCM-256 authenticated encryption algorithm and accommodates multiple encryption keys, making it a key subsystem in NANOsky avionics. SkyLabs end-to-end communication solution combines satellite command, monitor and management and payload data reception with SkyEGSE-comm SDR modem based on comprehensive NANOsky CMM software development kit.
