Ground-Based Global Navigation Satellite System (GNSS)-based Upper Atmospheric Realtime Disaster Information and Alert Network (GUARDIAN) GPS daily antenna phase maps (meta data, 24-hour files) from NASA CDDIS

This product contains file names and URLs to files containing antenna phase map data used in the real-time GPS POD processing. In particular, the IGS ANTEX file name used for the processing is provided. Additional meta data items may include information that identifies the real-time filter source populating the GPS real-time POD products (see "pos", "quat", and "tdp" products). The product is generated at JPL's Global Differential GPS Operations Centers.

本数据集包含用于实时GPS精密定轨（POD）处理的天线相位图数据文件的文件名及对应URL。其中特别提供了本次处理所用的IGS ANTEX（Antenna Exchange Format，天线交换格式）文件名。附加元数据项可包含用于标识生成GPS实时精密定轨产品的实时滤波器源的相关信息（详见pos、quat及tdp产品说明）。本数据集由JPL（喷气推进实验室，Jet Propulsion Laboratory）的全球差分GPS运行中心生成。
