Didn't anyone reply to this last time?
It sounds like the scheme you're describing is similar to ADS-B http://www.ads-b.com/
, a GPS-based traffic information system.
Without examining your claims about the FAA (including your numbers) too closely, I will simply say that I highly doubt the FAA or any controller is content with a system where the pirmary factor that determines the spacing of enroute aircraft is the resolution of the tracking radar. In fact, I challenge you to find someone who believes (who knows what they're talking about) that no improvements on the current ATC system are necessary.
Now as for Mr. Lans' system, its prudent to address a few shortcomings with a GPS-only-based traffic reporting system:
1.) The signal from a GPS satellite is relatively weak, only about 300 watts. This makes the potential for service interruption (unintentional or otherwise) a real possibility. Now what are you going to do when a bunch of aircraft aren't able to determine where they are or are reporting a wrong position based in incorrect data? You would almost need to have some sort of way to guarantee the quality and integrity of a GPS signal...lo and behold, the FAA
is developing a W
ystem (WAAS) so aircraft can operate in US airspace using a signal that the 'controlling authority' can ensure is available and accurate because they control it (and not the military). http://gps.faa.gov/Programs/WAAS/waas.htm
2.) Altitude information derived from uncorrected GPS data isn't all that great. In my experience, I've seen it be accurate to within 50 feet, with variations of up to several hundred feet among measurements. This is not precise-enough to attempt to measure the vertical speed of an aircraft and is in no way of higher fidelity that a good radio altimeter.
3.) Air traffic controlers are still an integral part of the system. The only thing that would change is the quality and source of the position data. As a bonus, the system has the potential to reduce voice communications by using digital data links between aircraft and the controller and among aircraft.
I would be very interested to know the source of the quote you stated in your post about a better mousetrap being damaging to the reputation of the U.S. Until then, I sleep soundly at night knowing Jane Garvey's goons can beat up anyone they want.
