Verification of Low Latitude Ionosphere Effects on WAAS During October 2003 Geomagnetic Storm
The Federal Aviation Administration’s Wide Area Augmentation System (WAAS) provides high integrity GPS-based precision navigation service to users in the conterminous United States. In October 2003, only four months after WAAS was commissioned, a series of coronal mass ejections from the sun triggered one of the strongest geomagnetic and ionospheric storms of the solar cycle. WAAS user integrit...
متن کاملTrans - ionospheric GPS signal delay gradients observed over mid - latitude Europe during the geomagnetic storms of October - November 2003
Ionospheric disturbances are known to have adverse effects on the satellite-based communication and navigation. One particular type of ionospheric effects, observed during major geomagnetic storms and threatening the integrity performance of both ground-based and space-based GNSS augmentation systems, is the sharp increase/decrease in the ionospheric delay that propagates in horizontal directio...
متن کاملThe response of the high-latitude ionosphere to IMF variations
The convection of plasma in the high-latitude ionosphere is strongly a2ected by the interplanetary magnetic 3eld (IMF) carried by the solar wind. From numerous statistical studies, it is known that the plasma circulation conforms to patterns that are characteristic of particular IMF states. Following a change in the IMF, the convection responds by recon3guring into a pattern that is more consis...
متن کاملPropagation of the October/November 2003 CMEs through the heliosphere
[1] The solar storms of late October, early November 2003 generated many ICMEs. The Wind, ACE, Ulysses, Cassini, Voyager 2, and Voyager 1 spacecraft are distributed throughout the heliosphere and observe the effects of these ICMEs. We investigate whether these ICMEs form a global merged interaction region. WIND, ACE, and IMP 8 data are combined to produce a plasma and magnetic field data set fo...
متن کاملModeling the 20 November 2003 Ionosphere Storm with GRACE
The Local Area Augmentation System (LAAS) provides differential GPS corrections for Category I precision approach to aviation users within tens of kilometers of the LAAS Ground Facility (LGF). To ensure integrity, any circumstance that may lead to hazardously misleading information (HMI) being transmitted to the user must be identified. If the probability of the situation exceeds the allocated ...
