Entering the vertical measurement (2 m) of a rover antenna:
$PASHS,ANT,0,0,2.000*2E
Entering the slant measurement (1.543 m) of the
ASH802147 antenna used at a base:
$PASHS,ANT,1.543,0.0980,-0.0400*07
Comments
• The vertical height from ARP to ground mark can also be
entered through the ANT command, which in this case
should be used as follows:
–
Set f1 and f2 to “0.0”
– Enter the antenna height from ARP to ground mark as
f3. Only when f1=f2=0.0 can you define f3 this way.
– f3 is negative when the ARP is below the SHMP.
• Parameters m4 and f5 are currently NOT processed in the
ProMark 800.
• Using this command is not recommended to enter a slant
height in the ProMark 800 for which f2 and f3 are hard-
coded (f2=0.098 m and f3= -0.04 m).
• When you enter an antenna height greater than 6.553 m
(see f1 and f2 above), be aware this will NOT be the value
of antenna height broadcast through RTCM messages and
the one saved to the G-file. Instead, a fixed value of 6.553
meters will be provided.
Parameter
Description
Range
f1
Slant height measurement, from ground
mark (GM) to antenna edge (SHMP).
0-6.553 m
6.553-100 m
f2
Antenna radius: horizontal distance from the
geometrical center to the antenna edge.
0-6.553 m
f3
Vertical offset:
• From ARP to SHMP, if radius and slant
height are not null.
• From Ground Mark to ARP, if radius and
slant height are null.
0 to ±6.553 m
6.553-100 m
m4
Horizontal azimuth [dddmm.mm], in degrees,
for the horizontal line connecting the ground
mark (GM) to the surveyed point (SP), mea-
sured with respect to WGS84 North.
