The main goal of this project proposal is to demonstrate the feasibility of scientific experiments aboard HALO during the ANTHALO Blue Ice (ANTHALO-BI) mission in Antarctica. In this context, a risk assessment has to be carried out. Furthermore, the scientific instrumentation for its integration into an extensive HALO scientific mission in Antarctica, the ANTHALO mission, is to be prepared. The operation of the aircraft with landing and taking off at a blue ice runway, together with measurements of GNSS reflectometry and INS strapdown vector gravimetry, is a core element within this project and a major, indispensable step towards the realization of ANTHALO. The main goals of the ANTHALO mission have to be kept in mind when realizing the present project. These are to gain consistent, highly accurate observations of the gravity and magnetic field of the Earth, of surface height, surface/firn properties, thickness and internal layering of the ice sheet, and of the thermal structure and dynamic regime of the middle atmosphere along long flight profiles over the Antarctic continent and, where pertinent, the adjacent Southern Ocean. The geodetic analysis of GNSS data will allow a determination of the flight trajectory in highly accurate coordinates, providing a common reference to the up-to-date International Terrestrial Reference Frame (ITRF) for all observables. To realize a reasonable coverage of measurements in Antarctica it is necessary to choose an airfield in Antarctica as the base for aircraft operations. Thus, the ANTHALO-BI mission will comprise blue-ice landing and taking-off, preferably at Troll Airfield (Dronning Maud Land, East Antarctica), and some flights at the margin of the Antarctic ice sheet, according to prescribed regulations of DLR-FX to operate the HALO in the Antarctic environment. Aboard ANTHALO-BI we aim to perform scientific measurements of strapdown vector gravimetry utilizing a specially calibrated Inertial Navigation System (INS), and of GNSS reflectometry using sideward and downward directed antennas. These measurements will be analysed to infer information on gravity-field related parameters and on surface heights in the marginal region of the Antarctic ice sheet. Four specific research proposals, directly linked to this proposal for the ANTHALO-BI mission, deal with various detailed scientific questions on investigating ice sheet, atmosphere and potential fields in Antarctica.

该项目提案的主要目标是证明南极洲Anthalo Blue Ice（Anthalo-Bi）任务中Halo上的科学实验的可行性。在这种情况下，必须进行风险评估。此外，要准备将其整合到Anthalo任务中的广泛的Halo科学任务中的科学仪器。飞机在蓝冰跑道上进行着陆和起飞的运行，以及GNSS反射测定法和Ins ints strapdown矢量重量表的测量，是该项目中的核心元素，也是实现Anthalo的重大，不可或缺的一步。在意识到当前的项目时，必须牢记Anthalo任务的主要目标。这些是为了获得一致的，高度准确的观察，对地球的重力和磁场，表面高度，表面/FIRN性质，冰盖的厚度和内部分层，以及中间大气的热结构和动态状态，沿着南极大陆上的长飞行剖面，以及在邻近的南部海洋。 GNSS数据的测量分析将允许在高度准确的坐标中确定飞行轨迹，从而为所有可观察物提供了对最新国际陆地参考框架（ITRF）的共同参考。要实现南极的合理覆盖范围，必须选择南极洲的飞机场作为飞机行动的基础。因此，根据DLR-FX规定的法规，在南极冰盖的规定中，Anthalo-BI任务将包括蓝冰登陆和起飞，最好是在巨魔飞机场（Dronning Maud Land，东北北极），在南极冰盖的边缘进行了一些飞行。在Anthalo-Bi上，我们旨在利用经过特殊校准的惯性导航系统（INS）（INS）和使用侧向和向下的定向天线进行反射量的科学测量。将分析这些测量值，以推断有关重力场相关参数以及南极冰盖边缘区域的表面高度的信息。四项针对Anthalo-BI任务的建议直接相关的特定研究建议，涉及有关调查南极洲冰盖，氛围和潜在领域的各种详细科学问题。
