摘    要:GPS能高精度地实时监测电离层总电子含量(TEC)变化,对纠正单频GPS接收机电离层延迟和监测电离层活动及其所反映的太阳活动规律具有重要意义.上海地区GPS综合应用网的建立,为监测长江三角洲地区电离层变化提供了宝贵的资料,利用这些双频GPS接收机的连续观测资料,可近实时地监测和预报该地区电离层总电子含量,其内外符精度和外推预报30分钟的精度均优于0.4m.

关 键 词:天体测量学  电离层  电子含量  GPS  太阳活动规律

Abstract:GPS can monitor the variations of the Total Electron Content (TEC) with ahigh precision, which is importantly significant to correct the ionospheric delay for single-frequent GPS receivers, to monitor the activity of ionosphere and to reveal active rule of theSun. The establishment of the Shanghai integration GPS network provides valuable datafor monitoring the real-time ionospheric variation of the Yangtse Rive delta region. Theextrapolated precise in 30 minutes and the internal and external precise of TEC from GridIonospheric Models are all smaller than 0.4m.
Keywords:astrometry: GPS  total electron content (TEC)
