When your CHCNAV GPS is not working, the receiver may fail to connect, show no position, lose RTK corrections, or provide inaccurate coordinates. These issues can happen because of weak satellite signals, incorrect configuration, outdated firmware, antenna problems, or communication failures.

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

Common CHCNAV GPS Problems

You may experience:

• CHCNAV GPS not turning on
• Receiver not connecting to controller
• No GNSS position
• No satellite signal
• RTK not fixed
• Incorrect coordinates
• LandStar connection errors
• Firmware update issues
• Bluetooth or Wi-Fi connection problems

Why Is My CHCNAV GPS Not Working?

Common causes include:

• Low battery or power issues
• Poor satellite visibility
• Loose antenna connection
• Incorrect receiver settings
• Lost RTK correction connection
• Outdated firmware
• LandStar software problems
• Network connection errors

Step 1: Restart Your CHCNAV GPS Receiver

A restart can fix temporary software and communication issues.

Steps:

1. Turn off the CHCNAV receiver.
2. Wait for 30 seconds.
3. Turn the receiver back on.
4. Restart your controller.
5. Open LandStar and reconnect.

Step 2: Check CHCNAV Power and Battery

If the receiver does not turn on or keeps shutting down:

Check:

• Battery level
• Charging cable
• Power connection
• Battery contacts

Try:

1. Charge the receiver fully.
2. Use the original charger.
3. Restart the device.
4. Check indicator lights.

Step 3: Check GNSS Satellite Signal

If CHCNAV GPS shows no location:

1. Move outdoors.
2. Place the receiver in an open area.
3. Keep the antenna facing upward.
4. Avoid buildings and trees.
5. Wait for satellite acquisition.

A clear sky view improves GNSS reception.

Step 4: Check Antenna Connection

Antenna issues can prevent the receiver from getting a position.

Inspect:

• GNSS antenna
• Antenna cable
• Receiver connector
• External antenna setup

Steps:

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

Step 5: Check LandStar Connection

If your controller cannot connect to CHCNAV GPS:

Try:

1. Open LandStar.
2. Check communication settings.
3. Confirm the correct receiver model.
4. Reconnect through Bluetooth, Wi-Fi, or radio.
5. Restart both devices.

Make sure LandStar is updated to the latest version.

Step 6: Verify RTK Correction Settings

If your CHCNAV GPS is not reaching Fixed status:

Check:

• NTRIP settings
• Correction source
• Internet connection
• Base station connection
• Mount point information

Steps:

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

Step 7: Check Receiver Configuration

Incorrect settings may stop the receiver from working properly.

Review:

• Base/Rover mode
• Coordinate system
• GNSS settings
• Data output settings
• Radio configuration

Restore saved configurations if settings were recently changed.

Step 8: Update CHCNAV Firmware

Outdated firmware can cause:

• Connection problems
• GNSS tracking errors
• RTK failures
• Software bugs

Steps:

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

Step 9: Update LandStar Software

An outdated LandStar version can cause compatibility issues.

Steps:

1. Check your current LandStar version.
2. Download the latest compatible version.
3. Install the update.
4. Restart the controller.
5. Connect your CHCNAV receiver again.

Step 10: Reset CHCNAV GPS Settings

If the receiver still does not work:

1. Backup important survey projects.
2. Open receiver settings.
3. Restore default configuration.
4. Reconfigure RTK and communication settings.
5. Test the receiver.
