Appeal No. 2002-0767
Application No. 09/382,381
In that regard, even if the aircraft in Denninger includes a
first positioning system antenna and receiver (i.e., GPS) and a
landing system antenna and receiver (i.e., ILS) that work
together to provide more accurate positioning information for use
in precision approaches and landings, there is no teaching or
suggestion in the Denninger patent of a "means" like that set
forth in the last clause of claim 1 on appeal, wherein the
enhanced position signal generated by that means includes a
correction factor based on "a vector representative of a
separation characteristic between said first positioning system
antenna and said first landing system antenna location." At
best, it would appear that Denninger discloses integrated multi-
mode receivers of the type mentioned by appellants on page 2 of
the specification, with an added radar altimeter input (AGL) to
provide more precise aircraft position information.
The examiner's theory that the attitude solution computer
(402) of Denninger corresponds to the means clause of claim 1 on
appeal is in error. As is made clear in the portion of Denninger
beginning at column 6, line 24 and continuing to column 7, line
17, the computer (402) of the attitude sensor (201) determines
the attitude of the aircraft in an earth-centered, earth-fixed
