What are we backing up?
There’s still talk of “sole-means” GPS WAAS
- Good system - gaining some acceptance as predicted
- Garmin hand-held WAAS receiver announced
- Raytheon marine WAAS plus GPS receiver vs: NDGPS
IRB investigated, found some of the usual faults
- Management tired, somewhat demoralized
- FAA should beef up its promotion of the system as a utility
- WAAS is on the air, and needs full funding
- Aviation use in 2003 -- likely earlier (even now) for others
