[amsat-bb] Falcon 9 Computer

[Don KB2YSI]

According to the user manual (
http://www.spacex.com/sites/spacex/files/falcon_9_users_guide_rev_2.0.pdf):
- Avionics
Falcon launch vehicle avionics, and guidance, navigation and control
systems use a fault-tolerant
architecture that provides full vehicle single-fault tolerance and uses
modern computing and
networking technology to improve performance and reliability. The fault
tolerance is achieved
either by isolating compartments within avionics boxes or by using
triplicated units of specific
components. Both the first and second stages host their own multiple
redundant lithium-ion
batteries to minimize the complexity of the electrical interface.

So whatever they are using they have 3 of them on board.
