Automatic Identification System
The Automatic Identification System (AIS) is a maritime transponder/receiver system defined by the IMO (international maritime organization) AIS operates in the VHF frequency band.
AIS is a system used by ships and vessels for identification at sea. AIS helps to resolve the difficulty of identifying ships when not in sight (e.g. at night, in radar blind arcs or shadows or at distance) by providing ID, position, course, speed and other ship data with all other nearby ships and VTS stations
AIS transceiver sends the following data every 2 to 10 seconds depending on vessels speed while underway, and every 3 minutes while vessel is at anchor. This data includes :
- MMSI number of vessel – vessel’s unique identification
- Navigation status – “at anchor”, “under way using engine” or “not under command”
- Rate of turn – right or left, 0 to 720 degrees per minute
- Speed over ground – 0.1 knot resolution from 0 to 102 knots
- Position accuracy
- Longitude – to 1/10000 minute and Latitude – to 1/10000 minute
- Course over ground – relative to true north to 0.1 degree
- True Heading – 0 to 359 degrees from eg. gyro compass
- Time stamp – UTC time accurate to nearest second when this data was generated
- Automatic identification of vessels and assist in target tracking.
- Safe marine traffic management.
- Instantaneous and effective implementation of search-and-rescue operations.
VMSMEA’s Satellite AIS provides effective communication among ships as well as from ship-to-shore which significantly improves situational awareness and better vessel identification, tracking and navigation. It also aids in search-and-rescue operations ensuring the security of the people as well as the vessel.
- Reliable and effective bidirectional voice communication from ship-to-ship as well as ship-to-shore.
- Efficient marine navigation and traffic control.
- On-time summoning the rescue services in case of emergency.
- Can be helpful as collision avoidance aid when used in accordance with the regulations.
A VHF marine radio is the single most important and reliable radio system for instant ship-to-ship and ship-to-shore communications intended mainly for short range communications. They save lives and are easy to use, moreover, being effective than mobile phones makes having a VHF a necessity no matter how small your boat is.
- Effective maritime monitoring, observation, and tracking.
- Quick responses to unusual activity or threats to security.
- High resolution satellite data ensures organized navigation and vessel manoeuvre.
- Port monitoring and alerting options.
A sophisticated technology solution and equipment for modern Vessel Tracking for enhanced communications, collision avoidance and positioning facilities ensuring safe navigation. Quick response to unusual activities serves towards improved safety and security in commercial maritime transportation.
Dual Mode Tracking
- Seamless communication in remote areas.
- Avoid cellular Blind Spots with reliable satellite coverage.
- Efficient data transmission like GPS position, sensor and vehicle alerts, text messages, etc.
- Maintain round-the-clock vessel visibility and security.
This technology uses a combination of Cellular Network as well as Satellite connection to provide resilient and reliable communications service. When the cellular network is weak or not available, it instantly switches to satellite mode to maintain accurate and timely updates until a stable cellular connection is established.
With two-way satellite connectivity, ideal for remotely monitoring and controlling assets.
Reliable connectivity in remote regions, even if the asset moves in and out of cellular range.
VMS Track Pro
The system allows persistent locating and monitoring of vessels and moving objects in a special area via VHF

The automatic identification system is an automatic tracking system that uses transceivers on ships to transmit a ship’s unique identification, position, course, and speed to other ships and coastal receivers. When satellites are used to detect AIS signatures, the term Satellite-AIS (S-AIS) is used.
VHF stands for Very High Frequency. Marine VHF radio is a worldwide system of two-way radio transceivers on ships and watercraft used for bidirectional voice communication from ship-to-ship and ship-to-shore.
