SSTL medium-class satellite platform family used for NovaSAR-1.

SSTL-300 is the medium-class SSTL satellite bus represented by NovaSAR-1. NovaSAR-1 is a 450 kg SAR Earth-observation mission, and the SSTL-MINI platform datasheet lists NovaSAR as an example SSTL-MINI configuration.^[1]^[2] The bus is mini-class by the 450 kg spacecraft mass. SSTL-MINI family figures include payload mass up to 200 kg and payload peak power up to 2000 W as family-level limits, not fixed allocations for every SSTL-300 instance.^[2]
