自1995年4月以来,EUTELSAT公司已使EUTELsAT Ⅱ FM1和热鸟-I(HB-1)两颗地球同步通信卫星共位于东经13°。本文介绍这两颗卫星的运行约束条件和轨道结构配置。此外,本文还介绍计划之中的使5颗和5颗以上卫星共位这一技术的发展过程。对这两颗卫星的约束条件为:经、纬度两轴的窗口为±0.1°;所有卫星都采取相同的位置保持策略;位置保持周期为14天,期间先执行一次北机动,周期为2天,随后12天执行一次东西机动;避免对多颗卫星同时执行机动;避免碰撞;避免卫星之间射频干扰的几何约束条件;星座增加或撤换卫星方便。基于上述约束条件和卫星位置理论不确定性,本文提出了控制的策略发展概念,阐明最好选择偏心率矢量差和倾角矢量差的组合控制方法,在此条件下可实现的最小星间距一般为6km(3σ值)。本文还介绍了目前所取得的共位实验的结果。最后,本文还论述了开发控制策略运行规划和监视软件的各种设施.
Since April 1995, EUTELSAT Corporation has positioned EUTELsAT II FM1 and HB-1 Geostationary satellites a total of 13 ° longitude. This article describes the operational constraints and orbital configuration of the two satellites. In addition, this article also describes the planned development of a technology that brings together 5 or more satellites. The constraint conditions for these two satellites are as follows: the latitude and longitude axes have a window of ± 0.1 °; all satellites adopt the same position keeping strategy; the position keeping period is 14 days; , Followed by 12 days to perform a maneuver; to avoid the simultaneous implementation of multiple satellites maneuver; to avoid collision; to avoid radio frequency interference between the geometric constraints of the satellite; the constellation to add or replace satellites convenient. Based on the above constraints and the uncertainty of satellite position theory, this paper presents the concept of strategy development for control, and illustrates the best combination control method of eccentricity vector difference and inclination vector difference. The minimum spacing achievable under this condition is generally 6km (3σ value). This article also describes the results of the co-located experiments that are currently available. Finally, this article also discusses the various facilities for developing control strategy operational planning and monitoring software.
