Key highlights
The NANOif-2 represents an intelligent remote terminal unit for interconnection of satellite's on-board sensors, instruments, or payloads into a seamless and unified on-board data handling architecture.
NANOif-2 support several highly configurable user interfaces, as discrete ADC channels, Digital Input/Output, or communication links as UARTs, RS422/485, SPIs, I2Cs, and auxiliary CAN. All the interfaces are seamlessly transformed into a standard NANOsky I TM/TC redundant CAN bus interface. The translation of user interfaces is performed in a way to provide maximal RTU independence to the user's higher protocols. Several intelligent built-in functions enable the use of the NANOif-2 RTU as a fully autonomous system, making the acquisition and conditioning of satellite sensors data practically autonomous.
Key features
User interfaces:
- 2x auxiliary CAN bus (CSP protocol)

- 8x GPIO with remap capability (GPIO, UART, SPI, I2C)
- User interfaces available on standard connector or alternatively support for legacy PC104 connector
Remote Terminal Interfaces:
- Redundant CAN interface for TM/TC.
4 Mbit NMV for housekeeping telemetry storage (unlimited read/write endurance).
Instant boot up at power on.
Comprehensive local subsystem telemetry (currents, voltages, temperatures, etc.).
Flight heritage
Flight proven on several missions.
