Web GUI Login

The Septentrio mosaic-G5 P3 module hosts a web interface for configuration, status, and diagnostics accessible via USB-C connector.

Connect

  1. Plug a USB-C cable from your computer to the USB-C port on the ARK G5 RTK GPS.

  2. Open a browser and go to http://192.168.3.1.

Log in

On recent Septentrio firmware the receiver enforces user authentication. The first time you connect, you will be prompted to create a new user account with a strong password.

Septentrio's factory credentials are:

  • User Name: RxAdmin

  • Password: S3pt3ntr10

Use these only to bootstrap the new account, then set your own credentials. Keep your new credentials in a safe place — if they are lost, the receiver must be reset following Septentrio's Lost Administrative Credentials procedure.

For the full procedure and rationale, see Septentrio's Cybersecurity guidelines: Log-in procedure.

Spectrum Analyzer

The web GUI includes a built-in RF spectrum analyzer under GNSS > Spectrum. It plots the live baseband spectrum at each GNSS band, which is the fastest way to spot in-band interference, jamming, or a mis-tuned antenna chain before it shows up as degraded fix quality. The AGC status for each band is shown under GNSS > Spectrum > Status.
