The design of the rest of MOST was inspired by and based on microsatellite bus designs pioneered by AMSAT, and first brought to commercial viability by the microsatellite company SSTL (based at the University of Surrey in the UK); during the early stages of MOST development, the core group of AMSAT microsatellite satellite designers advised and mentored the MOST satellite design team, via a know-how transfer arrangement with UTIAS. This approach to satellite design is notable for making use of commercial-grade electronics, along with a "small team," "early prototyping" engineering development approach rather different from that used in most other space-engineering programs, to achieve relatively very low costs: MOST's life-cycle cost (design, build, launch and operate) was less than $10 million in Canadian funds (about 7 million Euros or 6 million USD, at exchange rates at time of launch).
