A launch vehicle (e.g., a rocket) carrying a payload consisting of: 1) a first set of one or more satellites for delivery to a designated first orbit in a first orbital plane, and 2) a second set of one or more other satellites for delivery to a designated second orbit in a second orbital plane, is launched from earth in a conventional manner to an orbit in the first orbital plane where the satellites of the first set are released into the designated first orbit in the first orbital plane. Then, after the first set of satellites has been released, a first acceleration is imparted to the launch vehicle to change the inclination and the longitude of the ascending node of the launch vehicle by an appropriate amount so as to cause a nodal drift of the launch vehicle from the first orbital plane to the second orbital plane over a specified time interval. When the launch vehicle reaches the second orbital plane, a second acceleration is then imparted to the launch vehicle to counteract the change in inclination produced by the first acceleration--thereby causing the launch vehicle to be restored to the inclination that it had prior to the application of the first acceleration. The second acceleration stops the nodal drift of the launch vehicle, whereupon the launch vehicle assumes a relatively permanent orbit in the second orbital plane. The satellites of the second set are then released into the designated second orbit in the second orbital plane.
A method of dispensing a first satellite into a designated first orbit in a first orbital plane, and a second satellite into a designated second orbit in a second orbital plane, said first and second satellites being dispensed from a launch vehicle on a single launch, said method comprising the sequential steps of:
