What is NB-FPGA,
That will Enable the Advancement of Spacecrafts?
The Research and Development Directorate is leading the Innovative Satellite Technology Demonstration Program, which provides in-orbit demonstration opportunities to test equipment, parts, and microsatellites developed by private businesses and universities. One of such items loaded onto the first demonstration satellite is the NB-FPGA (NanoBridge-FPGA) developed by the Nippon Electric Company, Ltd. (NEC). FPGA is an integrated circuit where the functions can be customized in accordance to the user's intended use. Traditional FPGA made with semiconductor switch are susceptible to the effects of radiation, and are limited in how small they could be made because the memory for recording information need to be incorporated into them. On the other hand, the NB-FPGA uses an atomic switch that switches its wiring by moving metallic atoms. It reduces the ratio of errors occurring from the effects of radiation, while also making it possible to reduce its size and lessen the amount of power consumption. NEC says they applied for this program because they wished to verify radiation resistance in the extremely strong radiation environment of space.

Kiedys austraijczycy wyslali malego satelite FEDSAT ktory mog sie naprawic w kosmosie sam, w oparciu o logike
wczytana na nowo do FPGA. Takze MERy zawdzieczaja tej technologii swoj sukces.
Miejmy nadzieje, ze ostatnia misja satelity RAPIS-1 pozwolila japonczykom wzbogacic ich arsenal komponentow o te elementy.
