GPS Localization
This section lists possible GPS localization problems you may
encounter. If you still have problems after trying the solutions listed
here, contact TPS customer support.
Different channels are
used between the Base
Station and the Rover
machine. Check that the Base Station and Machine
use the same radio channel.
• For the Base Station, use the button on
the radio modem. See “Base Station
Initialization” on page 2-9.
• For the machine, use the control box
function. See “Configure Radios” on
page 3-63.
The radio antenna at
the Rover or Base may
be too low, incorrectly
placed, or too far away. If the yellow LED flashes when near the
Base Station, but not when farther away,
check that the Rover radio antenna mast is
mounted vertically at the highest point on
the machine.
If the Rover machine gets too far from the
Base Station, elevate the radio antenna at
the Base Station or move it to a closer
Control Point.
Problem
Measurement takes too long.
Causes
Solutions
The machine may be
blocking satellite
signals to the range-
pole 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 from the obstructions.
