Maxor Receiver Setup
Maxor Receiver Setup
Follow steps 1 through 3 to setup your receiver.
Step 1
Set up Receiver
This section assumes you have already configured your receiver using PCView.
1.
Place the Maxor on the appropriate tripod or bipod.
2.
Center the receiver over the point at which data will be collected. For most
applications, this should be at a location with a clear view of the sky.
Step 2
Measure Antenna Height
The location of the antenna relative to the point being measured is very
important for both surveys in which the elevation of the points is important and
in surveys for horizontal location only. Horizontal surveys are often larger in
area than can reliably fit on a flat plane, therefore the antenna adjustment must
be done in three dimensions and then projected onto a two dimensional plane.
The receiver calculates the coordinates of the antenna's phase center. To
determine the coordinates of the station marker, the user must specify the
following:
• Measured height of the antenna above the station marker
• Method of measuring the antenna height
• Model of the antenna used
Antennas have two types of measurements:
• Vertical – measured from the marker to the antenna reference point (ARP)
located on the bottom of the receiver at the base of the mounting threads.
• Slant – measured from the marker to the lower edge of the antenna slant
height measure mark (SHMM) located on both end panels of the receiver.
1.
Measure the antenna height above the point or marker (see “External
Antenna Setup” on page 3-4 for external antenna measurements and setup).
