When your CHCNAV GPS has signal problems, the receiver may show weak satellite reception, fail to achieve a GNSS fix, lose RTK status, or provide unstable positioning. These issues are commonly caused by poor satellite visibility, antenna problems, incorrect settings, firmware issues, or correction service failures.

This guide explains how to fix CHCNAV GPS signal problems step by step.

Common CHCNAV GPS Signal Problems

You may experience:

• Weak GNSS signal
• No satellite tracking
• CHCNAV GPS unable to get a fix
• RTK Fixed status lost
• Position jumping
• Slow satellite acquisition
• Signal loss during surveying
• Incorrect coordinates

Why Is My CHCNAV GPS Signal Weak?

Common causes include:

• Obstructed sky view
• Damaged GNSS antenna
• Loose antenna connection
• Incorrect receiver settings
• Electromagnetic interference
• Outdated firmware
• Poor RTK correction connection
• Software configuration errors

Step 1: Move CHCNAV GPS to an Open Area

GNSS receivers need a clear view of satellites.

Try:

1. Move the receiver outdoors.
2. Avoid buildings, trees, vehicles, and large obstacles.
3. Place the antenna upright.
4. Keep the receiver away from metal objects.
5. Wait several minutes for satellite tracking.

Open-sky conditions provide stronger and more stable GNSS signals.

Step 2: Check CHCNAV Satellite Status

Use LandStar software to check GNSS information.

Verify:

• Number of satellites tracked
• Satellite signal strength
• Position status
• Fix type
• PDOP value

If satellites are missing or signal levels are low, continue troubleshooting.

Step 3: Inspect the GNSS Antenna

A faulty antenna can cause signal problems.

Check:

• Antenna connection
• Antenna cable
• Receiver antenna port
• Physical antenna damage

Steps:

1. Turn off the CHCNAV receiver.
2. Remove the antenna connection.
3. Inspect connectors.
4. Reconnect securely.
5. Restart the receiver.

Step 4: Check GNSS Settings

Incorrect settings can affect satellite tracking.

Verify enabled systems:

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

Steps:

1. Open LandStar.
2. Connect to the CHCNAV receiver.
3. Open GNSS settings.
4. Enable available satellite constellations.
5. Save changes.

Step 5: Check RTK Correction Signal

If your CHCNAV GPS loses RTK signal:

Check:

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

Steps:

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

Step 6: Restart CHCNAV GPS Receiver

A restart can refresh satellite communication.

Steps:

1. Power off the receiver.
2. Wait for 30 seconds.
3. Turn it back on.
4. Open LandStar.
5. Check satellite reception.

Step 7: Check for Signal Interference

Avoid placing CHCNAV GPS near:

• Radio transmitters
• High-power electrical equipment
• Large metal surfaces
• Communication devices

Interference can reduce GNSS signal quality.

Step 8: Update CHCNAV Firmware

Outdated firmware may cause GNSS signal issues.

Firmware updates can improve:

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

Steps:

1. Connect the receiver through 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 cause communication or display problems.

Steps:

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

Step 10: Reset CHCNAV GPS Configuration

If signal issues continue:

1. Backup survey projects.
2. Restore receiver settings.
3. Reconfigure GNSS options.
4. Set RTK parameters again.
5. Test satellite reception.

A reset can fix incorrect configuration settings.
