If your Septentrio GPS stops working after an update, the issue may be caused by firmware compatibility problems, changed receiver settings, interrupted installation, communication errors, or configuration resets. Septentrio GNSS receivers rely on proper firmware, antenna setup, and configuration settings to provide accurate positioning data.

This guide explains how to fix Septentrio GPS not working after an update step by step.

Common Problems After Septentrio GPS Update

After an update, you may experience:

• Septentrio GPS not connecting
• No satellite tracking
• No position fix
• Receiver stuck during startup
• Incorrect location data
• Communication errors
• Loss of RTK corrections
• Navigation software not detecting the receiver

Why Is Septentrio GPS Not Working After Update?

Common causes include:

• Incorrect firmware version installed
• Configuration settings reset
• Update interruption
• Communication settings changed
• Driver compatibility issues
• Antenna or signal problems
• Correction service settings lost

Step 1: Restart Your Septentrio Receiver

A restart can resolve temporary update-related issues.

Steps:

1. Turn off the Septentrio receiver.
2. Disconnect the power supply.
3. Wait for 30 seconds.
4. Reconnect power.
5. Allow the receiver to boot completely.
6. Check GPS operation.

Step 2: Verify Firmware Installation

Check whether the update completed successfully.

Steps:

1. Open Septentrio RxTools.
2. Connect to the receiver.
3. Open receiver information.
4. Check:
   • Firmware version
   • Receiver model
   • Hardware compatibility

If the firmware does not match your receiver model, reinstall the correct version.

Step 3: Restore Previous Configuration Settings

Firmware updates may reset some settings.

Check and restore:

• GNSS configuration
• Communication ports
• Output messages
• Data logging settings
• RTK correction settings

Steps:

1. Open RxControl.
2. Load your saved configuration.
3. Apply settings.
4. Restart the receiver.

Step 4: Check the GNSS Antenna

An update-related issue may appear like a signal problem.

Check:

1. Power off the receiver.
2. Inspect the antenna connection.
3. Ensure the antenna cable is secure.
4. Check for cable damage.
5. Test the receiver outdoors.

Step 5: Check Satellite Tracking Status

Use RxTools to monitor satellite reception.

Verify:

• Satellites are visible
• Signal strength is normal
• Position fix is available
• GNSS systems are enabled

If no satellites appear, check antenna and configuration settings.

Step 6: Verify Communication Settings

After an update, communication settings may change.

Check:

• USB connection
• Serial port settings
• Ethernet/IP configuration
• COM port selection
• Baud rate

Reconnect the receiver and confirm your software detects it.

Step 7: Check RTK and Correction Settings

If you use high-precision positioning, verify:

• NTRIP settings
• Correction source
• Network connection
• Base station information

A reset after an update may remove saved correction settings.

Step 8: Update Septentrio Software Tools

Older software tools may not work correctly with new firmware.

Steps:

1. Install the latest Septentrio RxTools version.
2. Restart your computer.
3. Reconnect the receiver.
4. Test communication.

Step 9: Perform a Configuration Reset

If settings are corrupted:

1. Connect using RxControl.
2. Save current configuration if possible.
3. Restore default receiver settings.
4. Reconfigure required options.
5. Restart the receiver.

Step 10: Reinstall Firmware Update

If the receiver still does not work:

1. Confirm the correct firmware package.
2. Connect the receiver using a stable connection.
3. Reinstall the firmware.
4. Keep power connected during installation.
5. Verify the firmware version afterward.
