Key highlights
The NANOhpm-obc is a high-performance RISC-V on-board computer, designed for most demanding LEO applications.
NANOhpm-obc provides a versatile design in terms of variety of resources and available interfaces. The NANOhpm-obc is built on a robust NANOobc architecture, enhanced with significantly greater processing power, delivering 100 DMIPS at 50 MHz. It delivers Fault Tolerant NOEL-V processor (Cobham Gaisler - CAES) in peripheral rich SoC design. The NANOhpm-obc is delivered with flight proven NANOsky CMM Firmware framework, on top which application layer functions can be developed to suit any mission needs.
