/**
 *             [ANOTHER FINE PRODUCT FROM THE NONSENSE FACTORY]
 *
 * Flight software for the Longhorn Rocketry Association's Spaceport America
 * Cup 2020 rocket. Built for the LRA Generation 2 flight computer, which also
 * flies in LRA's NASA Student Launch 2020 rocket. The configurability of the
 * software--combined with modularity and all-in-one-package style of the
 * Generation 2 flight computer--means the software can be easily adapted to run
 * in any high-power rocket.
 *
 * @file      sac2020_profile.h
 * @purpose   Constants specific to the vehicle and flight profile including
 *            state transition time bounds, liftoff trigger, etc.
 *            Current configuration: SLI rocket, L1355 motor.
