The receiver cannot obtain Code Differential and/or 

RTK solutions.

Incorrect Base coordinates entered
Specify the correct coordinates for the Base station 

using NetView or another suitable field data collection 

software. 

The receiver is not configured as a Base or Rover.

If the receiver should function as a Base, ensure it 

has the proper configuration.

If the receiver should function as a Rover, ensure it 

has the proper configuration.

The corresponding receiver options may be disabled 

or expired.

See “Managing Receiver Options” for details on how 

to check current options.

Order a new OAF with the desired options activated 

to enable or extend validity of the corresponding re-

ceiver options. Contact your dealer or visit the JAVAD 

GNSS website for details.

Refer to the NetView Software Manual for a detailed 

description of options.

There are not enough common satellites. In order to 

obtain a fixed solution, the Base and Rover should track 

at least five common satellites.

Ensure that both the Rover and Base receivers use 

the same, and updated, almanac. 

Check the elevation masks of the Rover and Base 

receivers; they should be the same. See “TriPad 

Configuration” for information on setting the elevation 

mask.

A discrepancy exists between the differential stan-

dards used at the Base and Rover receivers. Ensure the 

Base and Rover receivers use the same corrections in-

put/output format:

Connect your receiver and a computer and start 

NetView. 

Click and the Ports tab. Use the same input/output 

format for both receivers.

Poor satellite geometry (PDOP/GDOP values are too 

high).

Conduct your measuring when PDOP values are low.
The elevation mask is above 15 degrees.
Lower the elevation mask. 
The transmitting and/or receiving antenna may be 

improperly connected.

Check that the radio modem’s antenna is securely 

and properly connected to the antenna connector.

Check that the radio modem’s antenna is undamaged. 

If damaged, contact your JAVAD GNSS dealer to re-

place the antenna.

The specified baud rate is incompatible with the baud 

rates the receiver supports.

The baud rate is the rate at which the receiver trans-

mits differential messages to the receiver and vice ver-

sa. Change the baud rate to that which your receiver 

supports.

The Base and Rover receivers use different radio link 

parameters.

Configure the Base and Rover radio receivers accord

-

ing to the procedures listed in the applicable section.

The distance between the Base and Rover is too far.
Close the distance between the Base and Rover.
Use repeaters to increase radio coverage.
There may be a source of radio interference that dis-

rupts radio communications.

Change the RF channel (if possible).
Use a spectrum analyzer to detect the radio charac-

teristics of the interfering signal and change your sys-

tem’s configuration accordingly.

Remove  the  source  of  jamming  signal  or  relocate 

your radio antennas (if possible).

The receiver does not start data logging
The memory option is disabled or expired.
Check that the memory option is enabled. For details, 

see “Checking an OAF” .

The receiver’s memory has no free space.

Download and/or delete data files to free up space for 

new files. Use the AFRM feature.
