• The rover is kept perfectly steady
during the static initialization.
Movements of even a few
centimeters only can cause
difficulties in post-processing of
such data, leading to unresolved
ambiguities and therefore poor
accuracy of the starting point as
well as all subsequently measured
points.
• A static re-initialization is always
carried out after a complete loss of
lock.
• Satellite geometry is strong. This
means that a minimum of 5
satellites should be visible
throughout the whole operation,
preferably 6 or more satellites.
Equipment setup for Kinematic and Stop & Go surveys
The System 500 rangepole is
designed such that either the
terminal or the sensor itself can be
attached easily. The length of the
rangepole is such that the total
instrument height of an AT501 or
AT502 antenna equals exactly 2
meters. All vertical antenna offsets
are taken care of.
See the Technical Reference Manual
for details on how to setup a System
500 sensor for kinematic and stop &
go surveys.
On the reference site static
measurements have to be taken.
Follow the instructions given in
chapters 1 to 4 with regard to
conducting static survey operations.
The roving sensor however might be
configured differently in order to allow
efficient operation while moving from
point to point.
The GPS antenna can be mounted
on a rangepole, and the sensor can
be stored in the System 500 Minipac;
alternatively the whole sensor can be
kept on the rangepole itself.
