为电离层闪烁研究开发的联网自主空间环境传感器全球定位系统软件定义接收器已部署在南极洲南极的自主自适应低功率仪器平台上。在本文中，我们描述了AAL-PIP实验装置，专注于案例。我们详细解释了分析病例数据的方法，并报告了最初的AAL-PIP病例结果。此外，我们比较的情况下，从修改后的Novatel GSV 4004 GPS电离层闪烁和TEC监视器（GISTM）接收器在南极的测量。CASES接收器已在赤道和中纬度地区成功部署并可靠运行。其中四个全球定位系统接收器首次部署在高纬度地区，作为国家科学基金会资助的自2010-2011年12月以来在南极洲部署空间科学仪器平台AAL-PIP项目的一部分。我们提出的初始闪烁的结果记录在南极的一个CASES接收器在2012年1月24日的风暴期间沿着AAL-PIP磁强计观测。我们推断CASES接收机闪烁观测与Novatel GPS闪烁接收机的观测结果一致。由于这是第一次部署CASES接收器在高纬度，低温和低湿度的环境中工作，我们认为这种比较证明了它作为科学级闪烁接收器在这种条件下的可靠运行。我们计划利用CASES和南极洲其他辅助仪器的观测结果，结合从模型中得出的物理参数，研究高纬度电离层的不规则性。
Connected Autonomous Space Environment Sensor (CASES) Global Positioning System (GPS) software-defined receivers developed for ionospheric scintillation studies have been deployed on Autonomous Adaptive Low-Power Instrument Platforms (AAL-PIP) at South Pole, Antarctica. In this paper, we describe the AAL-PIP experimental setup focusing on CASES. We explain in detail the method developed for analyzing CASES data, and report initial AAL-PIP CASES results. Furthermore, we compare the CASES measurements with those from a modified Novatel GSV4004 GPS Ionospheric Scintillations and TEC Monitor (GISTM) receiver at the South Pole. CASES receivers have been successfully deployed and reliably operated in equatorial and midlatitude regions. Four of these GPS receivers, for the first time, are deployed in high-latitude regions as a part of the National Science Foundation (NSF) funded project of deploying space science instrument platforms, AAL-PIPs, in Antarctica since December 2010-2011. We present initial scintillation results recorded by a CASES receiver at South Pole during the storm on 24 January 2012 along with AAL-PIP magnetometer observations. We have deduced that the CASES receiver scintillation observations agree with those from the Novatel GPS scintillation receiver. Since this is the first time a CASES receiver has been deployed to operate in a high latitude, low temperature, and low humidity environment, we consider this comparison a demonstration of its reliable operation as a science-grade scintillation receiver in such conditions. We plan to study high latitude ionospheric irregularities by using observations from CASES and other ancillary instruments from Antarctica coupled with physical parameters derived from models.
