• Restart the device after charging.

Step 3: Check GNSS Satellite Signal

If CHCNAV cannot calculate a position:

1. Move the receiver outdoors.
2. Avoid buildings and trees.
3. Place the antenna correctly.
4. Check satellite status in LandStar.
5. Wait for satellite acquisition.

Verify:

• Satellite count
• Signal strength
• Position status

Step 4: Check Antenna Connection

A faulty antenna can cause navigation problems.

Inspect:

• GNSS antenna
• Antenna cable
• Connector ports

Steps:

1. Power off the receiver.
2. Remove and inspect the antenna.
3. Clean the connectors if needed.
4. Reconnect securely.
5. Restart the receiver.

Step 5: Verify LandStar Connection

If CHCNAV GPS cannot communicate with the controller:

Check:

• Bluetooth connection
• Wi-Fi connection
• Radio connection
• Receiver selection

Solutions:

1. Open LandStar.
2. Remove the old connection.
3. Search for the receiver again.
4. Reconnect the device.

Step 6: Check RTK Correction Settings

RTK errors are common during surveying.

Check:

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

Steps:

1. Open LandStar.
2. Go to RTK settings.
3. Verify correction information.
4. Reconnect the correction service.
5. Check RTK status.

Step 7: Verify Coordinate System Settings

Incorrect coordinate settings can cause navigation errors.

Check:

• Coordinate system
• Datum
• Projection
• Zone settings
• Height parameters

Steps:

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

Step 8: Update CHCNAV Firmware

Firmware problems can affect receiver performance.

Updating firmware may fix:

• GNSS tracking issues
• Communication errors
• RTK problems
• Software bugs

Steps:

1. Connect CHCNAV 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An outdated LandStar version may create compatibility issues.

Steps:

1. Check your current LandStar version.
2. Install the latest compatible update.
3. Restart the controller.
4. Reconnect the receiver.

Step 10: Reset CHCNAV Configuration

If navigation errors continue:

1. Backup survey data.
2. Open receiver settings.
3. Restore factory defaults.
4. Reconfigure GNSS and RTK settings.
5. Test the receiver.
