Burst Mode Message Loss Effects On WAAS Availability
Burst Mode Message Loss WAAS Availability
2015/6/29
The Wide Area Augmentation System (WAAS) is a GPS based navigation aid currently under development by the Federal Aviation Administration (FAA). WAAS will provide corrections to aviation users for the...
A Simple Method of Signal Quality Monitoring for WAAS LNAV/VNAV
Signal Quality Monitoring WAAS LNAV/VNAV
2015/6/26
The integrity of the Wide Area Augmentation System (WAAS), being developed for the FAA, is of significant concern because of its intended use in commercial aviation navigation applications.
Adapting Kriging to the WAAS MOPS Ionospheric Grid
Adapting Kriging WAAS MOPS Ionospheric Grid
2015/6/26
The most productive way to increase the availability of single frequency users of the Wide Area Augmentation System (WAAS) is by decreasing the Grid Ionospheric Vertical Error (GIVE). Currently the GI...
The Effects of Large Ionospheric Gradients on Single Frequency Airborne Smoothing Filters for WAAS and LAAS
Large Ionospheric Gradients Single Frequency Airborne Smoothing Filters WAAS LAAS
2015/6/26
Both WAAS and LAAS receivers use carrier-smoothing filters to reduce the effects of multipath and thermal noise at the aircraft. For the majority of users this reduces the magnitude of the errors and ...
The Signal Quality Monitor (SQM) is an integrity monitor for the Wide Area Augmentation System (WAAS). The monitor detects L1 signal waveform deformation of a GPS or a Geosynchronous (GEO) satellite m...
Characterization of Signal Deformations for GPS and WAAS Satellites
Characterization Signal Deformations GPS WAAS Satellites
2015/6/25
Signal deformations are caused by imperfections or faults in the signal generating hardware onboard the satellites.Left uncorrected, these can lead to range errors. Thus they need to be measured and u...
Design and Implementation of Real-Time Software Radio for Anti-Interference GPS/WAAS Sensors
software-defined radio controlled reception pattern antenna (CRPA) Space-Time Adaptive Processing (STAP) radio frequency interference
2015/6/24
Adaptive antenna array processing is widely known to provide significant anti-interference capabilities within a Global Navigation Satellite Systems (GNSS) receiver. A main challenge in the quest for ...
Signal Deformation Monitoring for Dual-Frequency WAAS
Signal Deformation Monitoring Dual-Frequency WAAS
2015/6/24
Previous signal deformation analyses and monitor designs have primarily focused only on threats to the L1 C/A code. They have traditionally relied on a combination of empirical measurements and analyt...
