About
The Generic Nanosatellite Bus (GNB) is SFL’s entry-level nanosatellite bus, forming the structural and functional backbone of more than 20 missions across space astronomy, AIS ship tracking, and technology demonstration. At 6.5–7 kg with a 200×200×200 mm envelope, it represents SFL’s signature approach: maximum capability within minimum volume at minimum cost.
The GNB features triple-junction gallium arsenide solar cells with 26.8% beginning-of-life efficiency, a 3-axis attitude control system combining reaction wheels and magnetorquers capable of 1 arcminute pointing stability and 10 arcsecond attitude determination, and UHF/S-band communications. Notable missions include AISSat-1 (2010, world’s first AIS nanosatellite), all six BRITE-Constellation satellites (2013–2014, world’s first space astronomy nanosatellite constellation), CanX-4 and CanX-5 (2014, world’s first nanosatellites to demonstrate precision formation flying at sub-meter accuracy).
