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...
