The overall launch window is then obtained. 3 When the launch vehicle is the Shuttle, slightly different considerations apply for the launch window. These are outlined briefly here. Unlike conventional launch vehicles, for a Shuttle launch, the time of injection into transfer orbit is not closely tied to the time of launch. This is because there is flexibility in the selection of both deployment time and perigee stage ignition time, once the Shuttle has achieved the near-Earth parking orbit. Injection opportunities will occur every time the parking orbit crosses the Equatorial plane.

If it is within acceptable limits the manoeuvre is complete; if not, further manoeuvres are executed until the desired spin rate is obtained. 4 Ground Station Coverage 43 For example, the first ECS spacecraft was injected into transfer orbit by the Ariane 1 vehicle with a spin rate of 10 rpm. 5 rpm was required. The spin-up manoeuvre was executed in two phases. 5 rpm. The first manoeuvre was executed soon after injection into transfer orbit, while the second was carried out after first apogee passage, and after the execution of the first attitude slew manoeuvre.

The transfer orbit is the intermediate stage in a Hohman Transfer manoeuvre between the nearEarth, circular, parking orbit and the geosynchronous orbit, and as such, one apse is at parking orbit altitude, while the other is at geosynchronous orbit altitude.
