Typical Use
: Surveying Several Points within a Relatively
Small Area.
Key Instructions
:
1.
Two units needed: one stationary (the base) and the other (the rover)
moved successively on the points to be surveyed. There can be several
rovers logging data at the same time.
2.
Survey must start with an initialization phase (see page 42).
3.
Once initialization is achieved, be careful not to mask the rover’s
GNSS antenna throughout the survey. In case of satellite signal
loss, you will have to resume the initialization phase.
4.
Data must be collected simultaneously by the two units. We recommend
that you start the base first and you turn it off last. Use the same log-
ging interval on both units. Rover collects data continuously
throughout the survey.
5.
User-preset occupation (observation time) on each surveyed point.
Defaults: 5 min. on init point, 15 sec. on surveyed points. Countdown
tells the user when he/she can move to the next point.
Make sure the base is sited
in a clear area giving the
best possible view of the
sky!
When this is possible,
avoid trees, buildings or
any high obstacles in the
vicinity of the base.
Having a clear view of the
sky will allow the base to
collect data from a maxi-
mum of visible satellites,
which is highly recom-
mended to perform a suc-
cessful and accurate
survey.
