When your CHCNAV GPS shows “Location Not Found”, the receiver may fail to calculate its position because it is not receiving enough satellite signals, has incorrect configuration settings, or cannot connect to correction services. This issue can affect GNSS positioning, RTK status, and field surveying operations.

This guide explains how to fix CHCNAV GPS location not found problems step by step.

Common CHCNAV GPS Location Problems

You may experience:

• CHCNAV GPS location not detected
• No GNSS position available
• Receiver showing no coordinates
• RTK not fixed
• Position jumping or inaccurate
• LandStar unable to display location
• Satellite signal unavailable

Why Is CHCNAV GPS Location Not Found?

Common causes include:

• Poor satellite visibility
• Receiver used indoors
• Antenna connection problems
• Incorrect coordinate settings
• Disabled GNSS signals
• RTK correction failure
• Outdated firmware
• LandStar connection issues
• Weak internet connection

Step 1: Move CHCNAV GPS to an Open Area

GNSS receivers require a clear view of the sky.

Try:

1. Move the receiver outdoors.
2. Avoid buildings, trees, and large structures.
3. Place the antenna vertically.
4. Keep the receiver stationary.
5. Wait several minutes for satellite tracking.

A blocked sky view can prevent the receiver from calculating a location.

Step 2: Check Satellite Status in LandStar

Use LandStar software to check GNSS information.

Verify:

• Number of satellites tracked
• Signal quality
• Position status
• Fix type

If no satellites are visible, continue troubleshooting the antenna and receiver settings.

Step 3: Check CHCNAV Antenna Connection

A faulty antenna connection can cause location errors.

Inspect:

• GNSS antenna
• Antenna cable
• Receiver antenna port
• Connectors

Steps:

1. Turn off the CHCNAV receiver.
2. Disconnect the antenna.
3. Check for damage or dirt.
4. Reconnect securely.
5. Restart the receiver.

Step 4: Check GNSS Settings

Incorrect GNSS settings can prevent location detection.

Verify enabled satellite systems:

• GPS
• GLONASS
• Galileo
• BeiDou
• QZSS (supported models)

Steps:

1. Open LandStar.
2. Connect to your CHCNAV receiver.
3. Open receiver settings.
4. Check GNSS tracking options.
5. Save changes.

Step 5: Check Coordinate System Settings

Incorrect coordinate settings may make the location appear unavailable or incorrect.

Check:

• Coordinate system
• Datum
• Projection
• Zone settings

Steps:

1. Open the project settings in LandStar.
2. Verify coordinate parameters.
3. Select the correct coordinate system.
4. Save the project.

Step 6: Verify RTK Correction Connection

If CHCNAV GPS has no accurate location or remains in autonomous mode:

Check:

• NTRIP connection
• Base station connection
• Internet availability
• Correction source

Steps:

1. Open LandStar.
2. Go to RTK correction settings.
3. Confirm NTRIP details.
4. Reconnect corrections.
5. Check RTK status.

Step 7: Restart CHCNAV Receiver

Restarting can refresh satellite communication.

Steps:

1. Turn off the receiver.
2. Wait 30 seconds.
3. Turn it back on.
4. Open LandStar.
5. Check location status.

Step 8: Update CHCNAV Firmware

Older firmware may cause positioning problems.

Firmware updates can improve:

• GNSS tracking
• Satellite compatibility
• Receiver stability
• RTK performance

Steps:

1. Connect the receiver to LandStar.
2. Open receiver information.
3. Select firmware upgrade.
4. Install the latest compatible update.
5. Restart the receiver.

Step 9: Update LandStar Software

An outdated LandStar version can cause location display issues.

Steps:

1. Check the LandStar version.
2. Install the latest compatible version.
3. Restart the controller.
4. Connect CHCNAV GPS again.

Step 10: Reset CHCNAV GPS Configuration

If the location problem continues:

1. Backup project data.
2. Restore receiver default settings.
3. Reconfigure RTK settings.
4. Set the correct coordinate system.
5. Test positioning again.

• Charge the receiver before fieldwork.

Frequently Asked Questions

Why does my CHCNAV GPS say location not found?

This usually happens because of weak satellite signals, antenna problems, incorrect settings, or missing RTK corrections.

How long does CHCNAV GPS take to find location?

The time depends on satellite visibility, receiver conditions, and whether the device has recent positioning data.

How do I improve CHCNAV GPS location accuracy?

Use a clear sky view, correct antenna setup, RTK corrections, and updated firmware.

Can updating CHCNAV firmware fix location problems?

Yes. Firmware updates can improve GNSS tracking and receiver stability.

Conclusion

If your CHCNAV GPS location is not found, check satellite visibility, antenna connections, GNSS settings, coordinate configuration, and RTK corrections. Restarting the receiver, updating firmware, and reconnecting LandStar can resolve most location detection problems.

Proper setup, regular updates, and reliable correction services help maintain accurate CHCNAV GNSS positioning.
