Troubleshooting

This chapter will help you diagnose and solve some 

common problems you may encounter with your re-

ceiver.

Warning: 

Do not attempt to repair equipment yourself. Doing 

so will void your warranty and may damage the hardware.

Check This First!

Before contacting JAVAD GNSS support, check the 

following:

Check all external receiver connections carefully to 

ensure correct and secure connections. Double check 

for worn or defective cables.

Check all power sources.
Check that the most current software is downloaded 

onto the computer and that the most current firmware 

is loaded into the receiver. Check the JAVAD GNSS 

website for the latest updates.

Then, try the following:
Reset the receiver using NetView: Receiver name

If the problem persists, see the following sections for 

other solutions.

Receiver Problems

The following are some of the most commonly en-

countered receiver problems.

Cable specific problems

The cable is not properly plugged in.
Check that the cable connector is attached to the cor-

rect receiver port.

Unplug the cable, then securely and properly recon-

nect it to the receiver.

The cable is damaged.
Use an undamaged cable. Contact your Dealer to re-

place the cable.

Generic problems
The receiver port used for connection is not in 

Command mode.

Connect your receiver and a computer using a free 

port and start NetView.

Change the Input for the port used for connection to 

“Command”. 

The receiver does not lock on to satellites for a long 

period of time.

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.

The receiver tracks too few satellites
The elevation mask value is too high (above 15 de-

grees).

Lower the elevation mask. See “TriPad Configuration” 

for information on setting the elevation mask.

The measuring is conducted near obstructions (tree 

canopy, tall buildings, etc.).

Check that the Multipath Reduction boxes have been 

enabled.

Connect your receiver and a computer using a free 

port and start NetView.

Click enable Multipath reduction and click Apply.
Move to an area free of obstructions, if applicable. 
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.
