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 ...
