Introduce the reference frame and time system used in orbit design particularly. Analyzed the orbit characteristic of two-body problem and launch window.
My next launch window for a European trip isn't until school is over in June.
For an Aug. 5 liftoff, the launch window opens at 8:34 a.m. PDT 11:34 a.m.
The launch window remains open for one hour and 43 minutes.
Ares I-X has a four-hour launch window on Tuesday - from 8 a.m. to noon EDT (1200 to 1600 GMT) - during which the rocket needs only about 10 minutes of clear skies to get off the ground.
The launch window meeting the restriction of coplanar rendezvous and the characteristics of trans-lunar trajectory is obtained by precise dynamics model.
Based on the characteristics of launch window, an algorithm to calculate the launch window for space rescue mission was deduced.
In addition, an air launch promises a lot more scope to find a good "launch window" to get the spacecraft into orbit.
Moreover, the relation of initial launch condition and energy consumption is discussed in this paper, and the determination of launch window is given.
