Starlink User Manual

1. Preliminary Steps

Turn on the UGV and wait for the Starlink terminal status to show "Online."
Make sure the UGV’s onboard computer is connected to Starlink via Ethernet.
Open the Sirko-S1 control web panel in your browser (your server/domain address) — you received this address and access credentials with the drone.
Ensure the controller/joystick (USB/WebHID/WebGamepad) is connected if needed.

2. Login and Mode Selection

1) Log in to the web panel.

2) In the top menu, select the mode:

Operator — full platform control.
Observer — video and telemetry viewing only, no control.

3) Check the active communication channel: Starlink (indicator/badge "Starlink: Active").

| Note on automatic switching: The platform automatically uses the first available channel (ELRS or Starlink). If both are available simultaneously, the one that connects faster will be activated.

3. Telemetry and Safety

1) RTT (Ping) — channel quality indicator (lower ms = better). Color/zones:

Green: stable;
Yellow: acceptable delays;
Red: risk of lag.

2) POWER Relay - ON/Off — switch to the ON position.

3) ARM/DISARM:

Press ARM to prepare for movement (motor drivers activated).
Press DISARM to stop and cut power to the drives.
The system requires confirmation for ARM/E-STOP (protection against accidental activation).

4) Verify normal values: battery level, temperatures, GPS fix, and errors.

4. Video Streams (Front/Rear Cameras)

1) Main screen — Front camera; second stream — Rear camera (Picture-in-Picture with full-screen toggle).

2) For each camera, the following buttons are available:

HD/SD — switch quality (to save Starlink bandwidth).
On/Off — turn off the stream (to conserve bandwidth).
Full Screen — full-screen mode for the active camera.

3) Recommendations:

If RTT is high or packet loss occurs, reduce quality to SD.
Keep only the necessary stream active; turn others off.

5. Navigation Control (Virtual Joystick / Controller)

1) Tank-style control:

Vertical joystick (Left stick) — move forward/backward (up to ~11 km/h).
Horizontal joystick (Right stick) — turn (turn speed limited to ~5 km/h).

2) Speed indicator (color):

Green — low;
Yellow — medium;
Red — high.

3) E-brake / STOP — immediate drive stop (available on the control panel).

6. Connection Control

1) The status panel displays Starlink (RTT, stability) and ELRS/LRS (RSSI/LQ).

2) If Starlink degrades (RTT enters the red zone), the system:

Maintains control but recommends lowering video bitrate or turning off the second stream;
Automatically switches to the available radio channel (ELRS) if the Starlink connection is lost.

3) Notifications/alerts: "Link degraded," "Channel switched," "Video throttled."

7. Shutdown Procedure

Stop movement and press DISARM.
End recordings/streams and turn off any unnecessary cameras.
Exit Operator mode (switch to Observer or Logout).
If needed, disconnect Starlink/power following the proper procedure.
