IceBridge GPS L0 Raw Satellite Navigation Data, Version 1

This data set contains GPS readings over Antarctica using the Trimble Trimflite differential GPS Navigation System. The readings include latitude, longitude, track, ground speed, off-distance, Positional Dilution of Precision (PDOP), GPS height, easting, northing, and time taken. The data were collected by scientists working on the Investigating the Cryospheric Evolution of the Central Antarctic Plate (ICECAP) project, which is funded by the National Science Foundation (NSF) and the Natural Environment Research Council (NERC), with additional support from NASA Operation IceBridge.

本数据集包含基于天宝Trimflite差分GPS导航系统获取的南极地区GPS观测数据，观测项涵盖纬度、经度、航迹、地速、偏距、位置精度衰减因子（Positional Dilution of Precision, PDOP）、GPS高程、东向分量、北向分量以及采集时间。该数据由参与南极中部板块冰冻圈演化调查（Investigating the Cryospheric Evolution of the Central Antarctic Plate, ICECAP）项目的科研人员采集，此项目由美国国家科学基金会（National Science Foundation, NSF）与英国自然环境研究委员会（Natural Environment Research Council, NERC）资助，并获得NASA冰桥行动的额外支持。
