For launches into Earth orbit the main constraints are the desired orbit, the point of injection into that orbit, and the possibility of a collision with other orbiting spacecraft or orbital debris. For launches to interplanetary trajectories, the time of launch is constrained by the relative positions of the planets, at the time of both launch and encounter(i. e. the spacecraft must be aimed at a point in space that the planet will have reached by the time of encounter). A spacecraft launched outside the launch window would require more propellant and/or more time to reach its target.  2, record 1, English, - launch%20window

The POES satellites include an integrated system for guidance and control of orbital injection following separation from the Atlas vehicle. The Reaction Control Equipment(RCE) provides ascent phase, attitude control(3 axis), and orbital velocity trim for final injection. The RCE is operational from Atlas separation to handover to the orbital control system.  2, record 2, English, - reaction%20control%20equipment
