COLUMNS FORMAT DESCRIPTION DEFAULT VALUE & UNITS
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
(STATION POSITION SUBGROUP) is used
to identify the type of antenna used
at each station. For satellite antennae
the antenna number is obtained from
columns 11-12 of the OFFSET card.
The tables input on unit 22 must contain
2664 corrections for each antenna.
There is a separate phase correction for
each 5x5 degree block of azimuth and
elevation from elevation -90 degrees to
+90 degrees (37 values of elevation)
and from azimuth 0 degrees to 360 degrees
(72 values of azimuth) (2664=37x72).
As many as 49 antenna types can be input
simultaneously on unit 22. The table
of corrections for each antenna must
begin with a line that has 8 charac-
ters starting in column1:
ANTNO=NN
where NN is an integer from 1 through
49. After that there must be 333 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 (-85)-(-90) elevation
block. The first of the 9 lines for

ANTPHC (cont)
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 correction is in
meters. A positive number mean that
the antenna has caused the range
corresponding to the phase to be too
long. The correction will be subtracted
from the raw observation.
