Step 1: Restart Your NovAtel GPS Receiver

A simple restart can resolve temporary update-related issues.

Steps:

1. Turn off the NovAtel receiver.
2. Disconnect the power supply.
3. Wait for 30 seconds.
4. Reconnect power.
5. Restart the receiver.
6. Check GPS status.

Step 2: Verify Firmware Installation

Confirm that the update installed correctly.

Steps:

1. Connect the receiver using NovAtel software tools.
2. Open receiver information.
3. Check:
   • Firmware version
   • Receiver model
   • Software compatibility

If the firmware version is incorrect, reinstall the correct update package.

Step 3: Restore NovAtel Configuration Settings

Firmware updates may change or reset settings.

Check and restore:

If you created a configuration backup before updating, reload those settings.

Step 4: Check GNSS Antenna Connection

An update problem can sometimes appear as a signal issue.

Check:

1. Turn off the receiver.
2. Inspect the antenna connector.
3. Ensure the antenna cable is secure.
