The telemetry, tracking and control subsystem provides vital communication to and from the spacecraft TT&c is the only way to observe and to control the spacecraft's functions and condition from the ground October 29 2003 Massachusetts Institute of Technology

Background An icbm with a range of 6500 miles has a stagnation temperature of 12,000%F, 2000 f hotter than the surface of the sun Calculations showed that the optimum design for structural strength, resistance to heating, and free flight stability was a long, needle nosed reentry body But it would vaporize during reentry

Satellite communications Architecture Identify Requirements Specify architectures Determine link data rates Design Size each link Document your rationale

Overview Spacecraft data processing requires microcomputers and interfaces that are functionally similar to desktop systems However, space systems require: - Low power, volume, and mass High reliability and fault tolerance

Background OF TECHN Why is Software Engineering Hard? “Curse of flexibility \And they looked upon the software and saw that it was good. But they just had to add one other feature ... No physical constraints
