Continuous GNSS raw data measured from POLARSTERN deck during the MOSAiC expedition with POLARSTERN to the Arctic on 2019-12-18

Raw data acquired by a JAVAD Delta 3 GNSS Receiver with a resolution of 50Hz on board RV Polarstern during the MOSAiC expedition.
The data is stored in JAVAD's .jps format (JAVAD GNSS, GREIS – GNSS Receiver External Interface Specification, San Jose, USA, 2022 (download available at https://www.javad.com/jgnss/support/manuals.html)). Each file contains data of one day with a typical file size of 1GB. The receiver was equipped with a multi-frequency GNSS antenna which was mounted on the ship's observation deck. It has to be noted that the main mast and the ship's chimney lead to a shadowing of GNSS observation links in at least two directions seen from the antenna position. The data was collected for measuring scintillation activitiy in the central arctic. Processed scintillation measurements with a 1 minute resolution are available (doi:10.1594/PANGAEA.956019).

本数据集为MOSAiC科考航次期间，搭载于极地斯特恩号（RV Polarstern）考察船的佳瓦德Delta 3型全球导航卫星系统接收机（GNSS Receiver）所采集的原始数据，采样分辨率为50Hz。
数据以佳瓦德专用的.jps格式存储（佳瓦德全球导航卫星系统公司，《GNSS接收机外部接口规范（GREIS – GNSS Receiver External Interface Specification）》，美国圣何塞，2022年，下载链接：https://www.javad.com/jgnss/support/manuals.html）。每个文件包含单日观测数据，典型单文件大小约为1GB。
该接收机搭载多频全球导航卫星系统天线，安装于考察船观测甲板上。需注意：从天线位置观测，主桅杆与考察船烟囱会对至少两个方向的全球导航卫星系统观测链路造成遮挡。
本数据集采集目的为北极中部地区电离层闪烁活动观测。另有经处理的1分钟分辨率电离层闪烁测量数据集公开可用（doi:10.1594/PANGAEA.956019）。
