RTK Stake Out
Stake out with GPS is very similar to stake out with conventional
instruments. See the user’s manual for details on the different
staking procedures. Below is a description of the two special features
of stakeout with GPS.
o
!5RYLQJ / !2FFXS\LQJ
1. When you first start any GPS staking screen, measurements are
started in the GPS receiver in dynamic (moving) mode. This is
necessary as you navigate to the design point, and is indicated on
the screen with the toggle button in the
!5RYLQJ position.
2. When you arrive at the design point, if you want to take a more
precise measurement, you need to switch to
!2FFXS\LQJ mode.
This will switch the receiver from motion to static (depending on
your
Receiver Dynamics setting).
Note: When Store GPS Raw Data on the Job/ Settings/ Measure Mode
card is set to + Rx. Raw ( and / or +OBN for Ashtech) switching from
ROVING to OCCUPYING will start a session in the receiver, so you
will be prompted for a point name and description. The receiver
session will be completed and the measurement stored when you tap
'RQH. The occupation is not stored in the Survey Pro .RAW file if you
toggle back to ROVING.
o
+] 0RGH
1. When you first start any GPS staking screen, measurements are
started in the GPS receiver in one Hz mode. If your receiver
supports it, you can switch to five Hz mode by checking this
control. This will configure the receiver to calculate positions five
times a second and the display will update in near real time.
Note: Five Hz mode is for quick navigation to the point, it does not
provide the most precise solution of coordinates. When you switch
from roving to occupying, the receiver is automatically switched to
one Hz.
