GPS Localization
This section lists possible GPS localization problems you may
encounter.
Problem
Measurement takes too long.
Causes
Solutions
The machine may be
blocking satellite
signals to the rangepole or tripod-mounted
antenna.
Watch the status of the measurement
screen. If the status indicates “waiting for
satellites” move the machine away from
the antenna.
The Control Point may
be located too close to
obstructions.
Move to an alternative Control Point or
have the surveyor place a new Control
Point away form the obstructions.
The MC-2.5 Box has

system may be tracking
many satellites.
The range-pole was
unsteady.
Make sure that the pole is held steady
while measurement is taking place. Any
movement will make for a lengthy
initialization and/or measurement.
Problem
Localization produces large errors.
Causes
Solutions
A typographical error
occurred.
If errors are 10s or 100s of feet or meters,
it is likely that a typographical error has
occurred.
If coordinates are manually entered, check
that longitudes are correctly prefixed with
a minus sign if working in the western
hemisphere (for example, USA).
Re-enter the coordinates.
