Dataset from the ground-based TEC and scintillation receiver in Troll station for February 26-27 and March 18-19, 2018

Here present data from the GNSS Ionospheric Scintillation and TEC Monitor (GISTM) receiver NovAtel GPStation-6 that located at the Norwegian Research Station Troll in Queen Maud Land, Antarctica. The receiver records signals from the GPS, GLONASS, and Galileo satellites. Every minute, it provides extended summary messages, including satellite azimuth/elevation angles, C/NO, lock time, code-minus-carrier, calculations of amplitude (S4) and phase (σϕ) scintillation indices, and TEC. The data present after cut-off elevation angle of 30° to solve multipath effects. Time interval: 22:00-08:00 UT on February 26-27 and 17:00-06:00 UT on March 18-19, 2018. The data is presented as tables. Each .csv file contains data and header.本数据集源自安装于南极洲毛德皇后地挪威Troll研究站的NovAtel GPStation-6型全球导航卫星系统（Global Navigation Satellite System, GNSS）电离层闪烁与总电子含量（Total Electron Content, TEC）监测仪（GISTM）接收机。该接收机可接收全球定位系统（Global Positioning System, GPS）、格洛纳斯卫星导航系统（Global Navigation Satellite System, GLONASS）以及伽利略卫星导航系统（Galileo Satellite Navigation System, Galileo）的卫星信号。其每分钟生成一条扩展汇总报文，内容涵盖卫星方位角/仰角、载噪比（Carrier-to-Noise Ratio, C/NO）、锁定时长、码减载波（Code-Minus-Carrier, CMC）、振幅闪烁指数（S4）与相位闪烁指数（σ_φ）计算结果，以及总电子含量数据。本数据集已筛选仰角不低于30°的观测数据以抑制多路径效应。数据采集时段为2018年2月26日至27日的世界时（Universal Time, UT）22:00至次日08:00，以及2018年3月18日至19日的世界时17:00至次日06:00。数据以表格形式存储，每个.csv文件均包含观测数据与文件头信息。
