9.8.2.2 Static Phase
Static Phase collection is optimized for high accuracy single
point occupations, which require that each ambiguity
resolution be a separate calculation. In order to optimize this
collection, moving or kinematic chain data is not logged and
streaming occupation is unavailable.
In this configuration, the user will enter antenna height and
baseline length from the reference station. A status indicator
will then provide user feedback on the length of time needed
to occupy a point to provide a high level of confidence that the
ambiguity of the point will be resolved.
9.8.2.3 Kinematic Phase
Kinematic Phase collection is designed to resolve ambiguities
on an initial static point, and apply those same corrections to
all collected data within an unbroken “kinematic chain”. The
user is initially prompted to occupy a static point, and the
method of collection will be similar to that of static phase
collection. Once the point has been occupied for a sufficient
amount of time based on the status indicator, point and linear
streaming data can be collected in a normal fashion. If,
however, at any time the GPS lock drops below 4 satellites,
the phase chain will be broken and the user will be required to
initialize another static point.
9.8.2.4 The Interface
In order to select a mode of phase collection,
the user simply needs to press the menu button in the Codes
screen. The user will then have the ability to select from three
modes of collection:
1. No Phase
2. Static Phase
3. Kinematic Phase
