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 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 ...
متن کاملResponses of equatorial anomaly to the October − November 2003
The responses of Equatorial Ionization Anomaly (EIA) to the superstorms of October−November 2003 were investigated using the total electron content (TEC) measured with global positioning system (GPS) receivers in China, Southeast Asia, Australian (CSAA), and the American regions. Enhanced EIA was seen to be correlated with the southward turning of the interplanetary magnetic field Bz. In both t...
متن کاملMidlatitude daytime D region ionosphere variations measured from radio atmospherics
[1] We measured the midlatitude daytime ionospheric D region electron density profile height variations in July and August 2005 near Duke University by using radio atmospherics (or sferics for short), which are the high‐power, broadband very low frequency (VLF) signals launched by lightning discharges. As expected, the measured daytime D region electron density profile heights showed temporal v...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
