摘要

摘要: 基于子午工程北大深圳站（22.59°N，113.97°E）电离层GPS双频接收机在2011年1月1日至2017年12月31日连续7年的长时间序列闪烁和TEC观测数据，分析不同太阳活条件下华南赤道异常北驼峰区观测到的GPS卫星L波段电离层闪烁事件时空分布特征及其对通信的影响.结果表明：GPS闪烁事件几乎都发生在夜间，且主要发生在春秋分月份；在不同太阳活动条件下，夜间GPS闪烁事件都主要发生在北驼峰区域靠近磁赤道的一侧，且GPS闪烁事件存在明显的东-西侧天区不对称性，即在台站西侧天区发生的闪烁事件明显偏多；在不同太阳活动条件下，弱闪烁事件伴随的TEC耗尽和卫星失锁事件比例相对较低，强闪烁事件则大部分都伴随着TEC耗尽和卫星失锁事件的发生.

Abstract: The temporal and spatial variations of the ionospheric scintillation event and the influence on communication are studied using GPS measurements at Shenzhen station (Geographic latitude 22.59°N, Geographic Longitude 113.97°E, Geomagnetic Latitude 12.58°N) of Chinese Meridian Project, situated under the northern crest of the equatorial anomaly region, during the period from January 2011 to December 2017. The results show that: GPS scintillation events were largely a nighttime phenomenon, and most of the scintillation events were observed in equinox months; during different solar activity, scintillation events were mainly occurred at the inner edge of the northern crest of equatorial anomaly in China, and scintillation events are more probable to be observed in the west sector of the sky above Shenzhen station; during different solar activity, the weak scintillation events were relatively less accompanied by the TEC depletions and loss of lock on GPS signals, however, most of the strong scintillation events are accompanied by the TEC depletions and loss of lock on GPS signals.
