 ## Orbiter Avionics - Raspberry pi
 
-The pi is essentially a large disk (for geospatial db, holding avionics firmware, holding log data etc) and beefy CPU (for geospatial lookups, processing ads-b data, perhaps some data crunching for local optimizations based on weather) attached to the avionics. The pi is important, but not completely critical. It can crash (and if not fixed by watchdog) can remain offline and the orbiter can come in for service safely. We will utilize best practices with the pi, to ensure it's as reliable/avaiable as possible.

 In poc the pi will be attached via USB (and also serving as a host for the arduino for firware updates of the avionics ), in prototype/prod it will be on an integrated board as a Pi CM.
 
 * Payload power control:
 
-Control of the power payload, on a geospatial basis, in a black box/non customer changeable is also super critical, and will likely receive the second most regulatory scruity.
