Live AIS & NMEA view
Connect over Wi-Fi to a pilot plug, AIS receiver, NMEA TCP server or smart pilot plug device and view key movement values clearly.
Live navigation data viewer for Android
Pilot Plug
A clean professional viewer for AIS, NMEA and docking data - made for maritime pilots, captains and bridge officers who need live vessel movement information where it matters.

Why Pilot Plug
Navigation data, readable where full bridge systems are not always visible.
Pilot Plug helps show live vessel movement on a mobile Android device - on the bridge, on the bridge wing, during tests, training, monitoring and operational awareness.
COG, SOG, heading & ROT
Course over ground, speed over ground, heading and rate of turn - laid out with large values for quick interpretation under load.
Docking Mode display
Ship-silhouette view using standard maritime color coding - red port, green starboard - with bow, midship and aft movement information when available.
KA motion prediction
Docking Mode B (long press) uses a KA motion model to project heading and motion trends ahead - the same approach used by klaipedatraffic.lt for vessel forecasting.
Independent AIS / NMEA sources
Choose AIS and NMEA sources independently for position and heading - useful when one feed is more reliable than the other for a given value.
Automatic ship detection
Ship dimensions populate automatically from AIS Type 5 static reports as vessels appear in the stream - less manual setup before pilotage.
NMEA FREEZE for logbook
Freeze the live NMEA position values with one tap to capture a precise position entry for logbook or report use - without losing the live feed.
Clean dark interface
High-contrast dark UI with blue accents, large numbers and minimal distraction - designed to read well in real bridge lighting conditions.
Connection presets
Presets for common TCP data sources, or enter your own host and port for onboard testing and professional setups.
Docking Mode
Built for slow-speed vessel movement awareness.
Docking Mode focuses on the information that matters during close-quarters movement: how the ship is moving now, how the bow and stern are behaving, and how the trend may develop shortly ahead.
✓Ship silhouette with red / green port and starboard coding for instant orientation.
✓Bow, midship and aft motion indications when ship setup data is available.
✓Docking Mode B overlays a KA-based heading and motion prediction for projecting the next 15–90 seconds.
✓Large readable values sized for bridge and bridge wing use.
Data Sources
Connect to the navigation data you already have.
Pilot Plug is designed for practical onboard setups where NMEA or AIS data is available over a Wi-Fi TCP connection.
Pilot PlugUse data from a vessel pilot plug connection through a compatible adapter or server.
AISView live AIS-derived movement values when available in the connected stream.
NMEA TCPConnect to a TCP host and port over onboard Wi-Fi or a local device network.
Smart devicesWorks well with smart pilot plug bridges and test systems that output NMEA data.
Before you connect
A few setup notes worth knowing.
Most onboard NMEA / AIS Wi-Fi networks do not provide internet access. A few small Android behaviours are worth knowing before your first connection so the live feed stays stable.
01
Stay on the onboard Wi-Fi
When you join a Wi-Fi network without internet, Android may show a warning or try to switch back to mobile data. Choose Always connect or Keep using this network when prompted so the data stream is not interrupted.
Android notice02
Use the host and port for your source
Select a preset for common pilot plug bridges and AIS / NMEA TCP servers, or enter the host and port manually. Pilot Plug remembers recent connections for fast re-use during pilotage.
03
Confirm your ship setup once
For ships not auto-detected from AIS Type 5, confirm length, beam and antenna offsets once in Ship Setup. The bow / midship / aft display in Docking Mode uses these values.
Important safety notice
Pilot Plug is for testing, monitoring, training and situational awareness only. It is not approved as a primary navigation system. Do not use it as the sole source for navigation, collision avoidance, docking, pilotage or any safety-critical decision. Always use official ship instruments, approved navigational equipment, radar, ECDIS, visual lookout, bridge team procedures and professional judgement.
Available for Android
Bring live pilot plug and docking data to your Android device.
Install Pilot Plug, connect to your onboard NMEA TCP source, and view live movement data in a clean professional interface.
