[aprssig] APRS Speed Spec?

[Robert Bruninga]

Authors,

I thought that I had years ago declared that a speed of 999 would mean
Orbital Velocity 17,500 MPH and that 998 would mean something else for high
speed jets.  Maybe mach 3?



Actually  I may have defined three speeds greater than 999 for the last
three enetries.



Clearly we need orbital velocity for the Space station, etc…

And Mach 3 for our fighter pilots…

And something for the Concord (or its replacement)…

What about Elon Musk’s hypter tube?  But I think it is under 999…



Anyway, is this written down anywhere?



And if not, then here is what I propose:

999 = 17500 MPH space station

998 =   1850 MPH military

997 =   1350 MPH concord

996 =     996 MPH
