1-6 A6 ANTPHC - Requests the input of
tables with antenna specific
corrections to be used with GPS
phase data. The antenna corrections
are input on unit 22. When this option
is invoked, column 10 of the INSTRMNT
card is used to identify the type of
antenna used at each station. The
tables input in unit 22 must contain
1800 corrections for each antenna.
There is a separate phase correction
for each 5x5 degree block of azimuth
and elevation from elevation -35 to
+90 degrees (25 values of elevation)
and from azimuth 0o to 360o (72 values
of azimuth) (1800=25x72). As many as
9 antenna types can be input simulta-
neously on unit 22. The table of
corrections for each antenna must
begin with a line that has 7 characters
starting in column 1:
ANTNO=N
where N is an integer from 1 to 9.
After that there must be 225 lines of
antenna corrections. Each line contains
8 corrections (8D10.4). The first 9
lines are devoted to the 85-90 degree
elevation block. The next 9 lines are
devoted to the 80-85 degree elevation
block. The last 9 lines are devoted to
the (-30)-(-35) elevation block. The
first of the 9 lines for each elevation
block begins with the 0-5 degree azimuth
block. The second of the 9 lines for each
elevation block begins with the 40-45
degree azimuth block. The corrections is
in meters. A positive number means that
the antenna has caused the range corres-
ponding to the phase to be too long. The
correction will be subtracted from the
raw observation.
