By sending one or more telescopes into space, Space-VLBI (SVLBI) is able to achieve even higher angular resolution and is therefore the trend of the VLBI technique. For the SVLBI program, the design of satellite orbits plays an important role for the success of planned observation. In this paper, we present our orbit optimization scheme, so as to facilitate the design of satellite orbits for SVLBI observation. To achieve that, we characterize the uv coverage with a measure index and minimize it by finding out the corresponding orbit configuration. In this way, the design of satellite orbit is converted to an optimization problem. We can prove that, with an appropriate global minimization method, the best orbit configuration can be found within the reasonable time. Besides that, we demonstrate that this scheme can be used for the scheduling of SVLBI observations.

通过将一台或多台望远镜送入太空，Space-VLBI（SVLBI）能够实现更高的角分辨率，因此是VLBI技术的发展趋势。对于 SVLBI 计划，卫星轨道的设计对于计划观测的成功起着重要作用。在本文中，我们提出了我们的轨道优化方案，以便于设计用于 SVLBI 观测的卫星轨道。为了实现这一点，我们描述了uv用测量指数覆盖，并通过找出相应的轨道配置将其最小化。这样，卫星轨道的设计就转化为一个优化问题。我们可以证明，通过适当的全局最小化方法，可以在合理的时间内找到最佳轨道配置。除此之外，我们证明了该方案可用于 SVLBI 观测的调度。
