Set up HiPer+ Receiver
This section assumes you have already configured your
receiver using PC-CDU.
1. Place the HiPer+ 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.
3. If using the HiPer+ as a Base station, connect the
external radio to the receiver.
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.
