GPS use for NAV when coded not in WGS84

[Boroda]

GF,
The satellites might not be there or fail, but lat/longs are just there.

We will roll in but Is WGS84 ICAO standart or recommedation? I think the last one.

I asked about hydraulic meaning not system redundancy. It is something more important, something with world monopoly. When monopolist after some time starts thinking that his democracy is the most democratic in the world, his english is englisher than in England he tend to think that oil in another country is their oil because this part of the world is just coordinated in WGS84.

Don't take these words seriously - we are not soviet militarists anymore, I just want to show that alternatives are very important sometimes despite he fact their are stupid.
