on the different staking procedures. Below is a description of
the two special features of stakeout with GPS.
o
>Roving / >Occupying
¾ When you first open any GPS staking screen, the GPS
receiver is 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
>Roving position.
¾ When you arrive at the design point, if you want to
take a more precise measurement, you can switch the
receiver to static mode by tapping the toggle to
>Occupying . This will change the receiver dynamics
(depending on your setting) and allow for the most
precise measurement on the design or as built point.
Note: When Store GPS Raw Data on the Job | Settings |
Measure Mode screen 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 Done.
o
5 Hz Mode
The default behavior for stake out is to start all staking
screens in 5 Hz update mode. This sets the receiver to
update positions five times a second to make it easier to
find the design point when in >Roving mode. However,
the receiver is always less precise in 5 Hz mode, so when
you toggle to >Occupying, we automatically set the
receiver to One Hz updates to allow for the most precise
measurement
You can turn 5 Hz Mode on or off when you are roving
using the check box. You can override the default
behavior on the Job | Settings | Stakeout screen.
