NANOcomm-2 (2nd Generation)
Miniaturised full-duplex TM/TC communication subsystem in UHF/VHF frequency bands and CCSDS compliant
NANOcomm-2 is a highly miniaturised TM/TC satellite communication subsystem. It provides a full duplex satellite communication link and thus enables improved communication data link budgets. Its best-in-class SWaP (Size, Weight and Performance) characteristics assure the NANOcomm-2 outstanding performance for the emerging space market. The NANOcomm-2 has embedded intelligence, powered by PicoSkyFT, contributing directly to the overall satellite system functionality. Several intelligent built-in functions enable the use of the NANOcomm-2 as a fully autonomous system, making the acquisition of satellite diagnostic data practically autonomous. NANOcomm-2 represents a key subsystem in the NANOsky 2nd generation platform due to its performance enchantments and its multifunctional architecture.
Features
Highly miniaturised NANOcomm-2 features full duplex communication, compliant with the CCSDS protocol, while supporting configurable modulation schemes, parameters and data rates. High reliability is ensured via carefully selected parts and combined with an advanced FDIR approach that supervises the SDR logic and other critical parts of the subsystem. Its fault tolerance by design provides remarkable reliability and robustness against SEE. Fault tolerance is assured by redundancy on the component level and their flight heritage, latch-up protection by constant current monitoring and several mitigation techniques. The NANOcomm-2 is powered by PicoSkyFT to further enhance the safe operation of its processing functions. NANOcomm-2 features standard TM/TC channel via redundant CAN buses and a high speed LVDS interface.
NANOcomm-2 consists of the following features:
- UHF and VHF full-duplex transceiver
- Adjustable parameters of RF transceiver
- Two independent RF transceivers chains for superior reliability
- RF power output of up to 31 dBm
- LNA on the receive path
- Interface and Control Unit in a robust FPGA system
- NVM memory storage for HSK TM logs
- Comprehensive local subsystem telemetry (currents, voltages, temperatures, etc.)
- Interfaces:
- Dual LVDS or RS422 interface links
- Redundant CAN interface for TM/TC
- Optional 8 GPIOs with interface remapping capability (SPI, I2C, UART, GPIO)
Software support
NANOcomm-2 ha s a flight proven functionality. It is delivered with skyEGSE-GUI application to enable user immediate out of the box control, monitor and management of the equipment.
NANOcomm-2 is compliant with optional NANOsky CMM™ SDK that provides all functions to support controlling, monitoring and management of NANOcomm-2 equipment. All functions are provided in a comprehensive C++ library, with application-level examples for fast prototyping or functionality integration to a third-party software. This enables users a drastic savings in the development time for integration of SkyLabs equipment functions into customer specific EGSE, AIV/T or even MOC software.
