I agree, but what is ITU? (Presumably not International Telecommunications
Union.)  Oh, I got it: GLONGITU and GLATITUD! But then is the "bandwidth" being used to convey more information? How about TELxLON and G TELxLAT (x = A | G)?
TEL is nicely obvious as the phase centre of an array too.

B.t.w., how do we establish a standard if we achieve concurrence?
