Troubleshooting

Receiver Problems

www.javad.com

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 and start TriVU. See “Connecting the Receiver

and a Computer” on page 25.

• Click Configuration

Advanced and the Multipath Reduction tab. Enable the two boxes

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 TriVU 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. See

Chapter 3 for details.

• If the receiver should function as a Rover, ensure it has the proper configuration. See

Chapter 3 for details.

The corresponding receiver options may be disabled or expired.

• See “Managing Receiver Options” on page 60 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 receiver options. Contact your dealer or visit the JAVAD GNSS website for
details.

• Refer to the TriVU 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. See

“Collecting Almanacs and Ephemerides” on page 28.

• Check the elevation masks of the Rover and Base receivers; they should be the same. See

“TriPad Configuration” on page 43 for information on setting the elevation mask.

A discrepancy exists between the differential standards used at the Base and Rover receivers.
Ensure the Base and Rover receivers use the same corrections input/output format:

1. Connect your receiver and a computer and start TriVU. See “Connecting the Receiver and

a Computer” on page 25.

2. 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.
