NANOcomm is a CCSDS compliant full-duplex communication subsystem with an SoC design approach providing UHF downlink and VHF uplink. The full-duplex architecture of the NANOcomm supports data rates of up to 32.8 kbps, different modulation schemes and is capable of delivering up to 2 W output power. The NANOcomm has been designed to provide low power consumption in the receiving mode. The advanced FDIR policy with transceiver redundancy, hot redundant CAN buses and Direct Command Interface provide a highly reliable standard TM/TC channel.
NANOcomm is a CCSDS compliant VHF/UHF full-duplex communication subsystem designed to provide a highly reliable TM/TC channel. The fault tolerant design incorporates various error mitigation techniques including redundancy on all critical signal paths. The main communication interface is provided via hot redundant CAN buses. In addition, the subsystem provides a Direct Command and Telemetry Interface for the wire-based control of other subsystems allowing operators to control basic functions of the spacecraft by bypassing the data handling subsystem.
