    • The effect of orbit plane precession is used to place a plurality of satellites into one or more desired orbit planes. The satellites are distributed within each desired orbit plane in a selected configuration. The satellites are transported into orbit on one or more frame structures referred to as "pallets". When more than one pallet is used, they are placed on top of each other in a "stack". After the stack of the pallets has been launched into an initial, elliptical orbit, the pallets are separated sequentially from the stack at selected time intervals. Thrust is applied to transfer a first pallet from the initial orbit to a first, circular orbit, wherein the initial and first orbits are in planes that process at different predetermined initial and first rates, respectively. After waiting for a predetermined time while the initial orbit plane and the first orbit plane precess with respect to each other, thrust is applied to the next pallet to transfer it into a next, circular orbit in a next orbit plane, wherein the precession rate of the next orbit plane also is different from the initial precession rate of the initial orbit plane. The foregoing step is repeated until the satellites on the respective pallets have been sequentially deployed into the desired orbit planes. The satellites on each pallet are then separated from the pallet simultaneously, but at different rates to achieve separation among the satellites within each orbit.
    • 使用轨道平面进动的效果将多个卫星放置在一个或多个所需的轨道平面中。 卫星以选定的配置分布在每个所需的轨道平面内。 卫星在被称为“托盘”的一个或多个框架结构上被运送到轨道中。 当使用多个托盘时,它们以“堆叠”的形式放置在彼此的顶部。 在托盘的堆叠已经被启动到初始的椭圆轨道之后,托盘以选定的时间间隔从堆叠中顺序地分离。 施加推力以将第一托盘从初始轨道传送到第一圆形轨道,其中初始轨道和第一轨道分别处于以不同预定初始速率和第一速率处理的平面中。 在初始轨道平面和第一轨道平面相对于彼此进动的等待预定时间之后,将推力施加到下一个托盘以将其转移到下一个轨道平面中的下一个圆形轨道中,其中进动速率 下一个轨道平面也不同于初始轨道平面的初始进动速率。 重复上述步骤,直到相应托盘上的卫星已经顺序地部署到期望的轨道平面中。 然后,每个托盘上的卫星同时与托盘分离,但以不同的速率分离,以实现每个轨道内卫星之间的分离。
