We discuss two geosynchronous gravitational wave (GW) mission concepts, which we generically name gLISA. One relies on the science instrument hosting program onboard geostationary commercial satellites, while the other takes advantage of recent developments in the aerospace industry that result in dramatic satellite and launching vehicle cost reductions for a dedicated geosynchronous mission. To achieve the required level of disturbance free-fall onboard these large and heavy platforms, we propose a new drag-free system, which we have named "two-stage" drag-free. It incorporates the Modular Gravitational Reference Sensor (developed at Stanford University) and does not rely on the use of μN thrusters. Although both mission concepts are characterized by different technical and programmatic challenges, individually they could be flown and operated at a cost significantly lower than those of previously envisioned gravitational wave missions, and in the year 2015 we will perform at JPL a detailed selecting mission analysis.
我们讨论了两种地球同步引力波（GW）任务概念，我们将其统称为gLISA。一种依赖于地球静止商业卫星上搭载科学仪器的计划，而另一种则利用了航天工业的最新发展成果，这些成果使得专门的地球同步任务的卫星和运载火箭成本大幅降低。为了在这些大型重型平台上实现所需的无干扰自由落体水平，我们提出了一种新的无拖曳系统，我们将其命名为“两级”无拖曳系统。它集成了模块化引力参考传感器（由斯坦福大学开发），并且不依赖于使用微牛顿推进器。尽管这两种任务概念都面临不同的技术和计划挑战，但它们各自都可以以远低于先前设想的引力波任务的成本进行飞行和运行，并且在2015年我们将在喷气推进实验室进行详细的任务选择分析。
