notes "computers in space" Tomayko

1. simulations
2. testing when prelaunch
3. automated launch
3. control while moving(also robots)

gemini software(first computer in space):
    executor   - execute programs of mission
    prelaunch  - ground check
    ascent     - launch
    catch-up   - change orbit and intercept object
    rendezvous - closing and keeping
    re-entry   - return program
*first machines was with permanent memory(without delete)

for safety in calculating possible use three machines simultaneously and check solutions with each other while calculating(2:1 voting)

embedded computers - onboard computers in space craft
*like a controllers for parts in the rocket, for example for engine launch
**monitoring own part and run/stop - also under control of outboard system

!vector mathematics

deep-space missions:
-launch
-midcourse maneuver
-cruise
-encounter
*onboard computers have own clocks for changing programs by timings
**telemetry output
