抽象的。我们介绍了位于南极洲的一台新的低成本倾斜电离层探空仪的首次观测结果。发射器位于罗斯岛的麦克默多站，接收器位于南极的阿蒙森-斯科特站。该系统于2019年3月成功演示，该实验在两周内产生了超过3万个电离层回波。这些数据表明，存在一个稳定的E层和一个零星和可变的F层，其显著扩展-F有时超过500公里(以虚拟高度为单位)。最重要的电离层参数NmF2与Jang Bogo VIPIR电离层探空仪(在1000多公里外观测)进行了很好的验证。从MIDAS算法获得的GPS TEC数据可以被认为是必要的，但不足以预测麦克默多和南极之间的7.2 MHz传播，在40%的情况下得出真阳性，在73%的情况下得出真阴性。这一试点实验的成功，总赠款费用为116K美元，设备费用约为15000美元，这表明可以建立一个大型多基地网络，以提供对南极电离层前所未有的观测覆盖。
Abstract. We present the first observations from a new low-cost oblique ionosonde located in Antarctica. The transmitter is located at McMurdo Station, Ross Island and the receiver at Amundsen-Scott Station, South Pole. The system was demonstrated successfully in March 2019, with the experiment yielding over 30 000 ionospheric echoes over a two-week period. These data indicate the presence of a stable E-layer and a sporadic and variable F-layer with dramatic spread-F of sometimes more than 500 km (in units of virtual height). The most important ionospheric parameter, NmF2, validates well against the Jang Bogo VIPIR ionosonde (observing more than 1000 km away). GPS-derived TEC data from the MIDAS algorithm can be considered necessary but insufficient to predict 7.2 MHz propagation between McMurdo and South Pole, yielding a true positive in 40 % of cases and a true negative in 73 % of cases. The success of this pilot experiment at a total grant cost of $116k and an equipment cost of ~$15k indicates that a large multi-static network could be built to provide unprecedented observational coverage of the Antarctic ionosphere.
