Troubleshooting

Step 2. Is the

Radio Antenna

Connected to the

Radio Module?

The radio module cannot operate properly without an
antenna. Make sure the antenna is connected to the radio
module.

1. If the antenna is not connected, connect the radio

antenna (provided in the radio receiver kit) to the radio
module. Ensure that the connection is secure. If the
problem is not yet resolved, go to step 3

2. If the antenna is connected, ensure the connection to the

radio module is secure. If the problem is not yet resolved,
go to step 3.

Step 3. Are the

Rover Radio

Settings

Compatible with

those of the Base

Radio?

The rover radio must use settings that are compatible with
those of the base radio, in order for the rover to receive
corrections from the base. (This means you are supposed to
know the currently used base radio settings.)

1. Check the radio settings in the rover:

Use $PASHQ,RDP,PAR or FAST Survey (

Equip menu>GPS

Rover>RTK Tab, Device field,

) to check the frequency,

protocol and “Over the Air” baud rate used.

2. If the rover radio is set properly, go to step 4.

Step 4. Is the Line

of Sight Between

the Base and the

Rover Antennas

Obstructed?

Although radios are fairly robust, an excessive amount of
obstructions can block out the signal.

1. If the line of sight is not obstructed, go to step 5 below.

2. If the line of sight is obstructed:

• Move to a less obstructed location. In order to test if

the system is functioning properly, move to a location
that does not have an obstructed view between the
base and rover radio antennas.

• If this is not possible, move to higher ground or a

location where there is less obstruction.

• If, after moving, the rover radio begins to receive data

from the base, then the previous location is too
obstructed from the base. You will need to either raise
the base radio antenna higher, or move the base to a
location with less obstruction between the base and
rover radio antennas.

3. If the problem is not yet resolved, go to step 5.
