Questions on high altitude pressures
Anthony will never admit that he's wrong, nor will he ever accept a point of
view offered by others. This is why he is a social outcast and can not find or hold a job. |

Questions on high altitude pressures
And please remember that GPS altitude is based on an "imaginary"
or mathematical model of the earth's surface. Right now I have mine set to WGS 84. But there are numerous other geodetic datums, such as WGS 72, Zanderij, and so on. |

I can point you to dozens of sites that "prove" that Denver's airport overlies a huge alien base underground, but that doesn't make it so. Kewl! Tell me where, and I'll drive over and check it out! |

WAAS most certainly is part of the GPS system, LAAS is in development, and differential is a matter of interpretation. You won't see any improvement from WAAS because France isn't in the current service area. If you don't like those examples of GPS system improvements, here are some of the following since 1978: Six distinct satellite families, each progressively better, 1978-2009. SA turned off circa 2000. L2C added to Block IIR-M and newer satellites circa 2005. Total of 31 satellites and the constellation changed to a nonuniform arrangement circa 2008. The CNAV message added to upgrade the original NAV message. The L5 and the L1C messages in work. Further improvements, called GPS III, are planned to be all operational by 2013, with incentives offered to the contractors if they can complete it by 2011. In summary, you don't know **** from shinola about how GPS works or the history of GPS. -- Jim Pennino Remove .spam.sux to reply. |

Consumer hiking receivers generally don't have such capabilities. -- Jim Pennino Remove .spam.sux to reply. |

They are separate systems that depend on GPS; they are not part of GPS. Anyone can construct a GPS augmentation system, but that doesn't make it part of GPS. You won't see any improvement from WAAS because France isn't in the current service area. That does not change the fact that WAAS is not part of GPS. Drooling nonsense. You obviously haven't a clue how WAAS works. -- Jim Pennino Remove .spam.sux to reply. |
