broadcast map would not be as good as having an extended WAAS map in the first
place. This difference may lead to minor accuracy degradation.
Figures C-3 and C-4 depict the broadcast WAAS ionospheric map extent and the
extrapolated version, respectively. As can be seen from Figure C-3, the coverage
compared to Figure C-1 extends further in all directions, enhancing usable coverage.
Similar to the WAAS ionospheric map extrapolation, Figures C-5 and C-6 depict the
broadcast EGNOS ionospheric map extent and the extrapolated version, respectively.
As can be seen from Figure C-6, the coverage compared to Figure C-5 extends further
in all directions, enhancing usable coverage.
