Using the current Navigation
Position
To use the current navigation position
as the coordinates for the reference
point, press the HERE (F4) key.
The current navigation position will be
taken. Input the Point Id and press
STORE (F1). The point will be added
to the database and will be taken over
into the Main Survey screen.
Measure and input the Antenna
Height (Ant Height). When using a
Tripod this will be measured using the
Height Hook.
Further details on measuring the
Antenna height can be found in
section 2.15.
The navigated position is normally
used in preference to the Single Point
Position (SPP) if there is no previ-
ously measured point available and
the baseline between Reference and
Rover is 5km or less. In situations
where the baseline is greater than
10km, it is probably better to use
SPP.
Using Single Point Position (SPP)
A SPP is where the GPS code
observations for a single point are
collected over a period of time and
refined into a position that is generally
more accurate than a navigated
position.
To activate the Single Point position-
ing, press SPP (F6).
The suggested Point Id is automati-
cally created based on the Time and
Date Point Id Template. It may if
required be overwritten. The Time
and Date Point Id Template follows
the following format:
