AIS Data Sharing
The function of AIS centers on two main types of equipment: Class A transceivers, which are mandatory for all large ships under the International Maritime Organization (IMO) regulations, and Class B transceivers, used by smaller vessels that are not required to carry the system. These devices exchange data with other nearby ships and AIS base […]
The Intersection of AIS and Marine Insurance
Risk Assessment with AIS Data AIS equips insurers with a comprehensive view of navigational patterns by constantly transmitting necessary data such as location, speed, and vessel type. This influx of granular, data stands in contrast to older methods that often relied on broader, less timely information. Insurers can now observe whether a ship is adhering […]
Enhancing Maritime Domain Awareness with AIS
AIS is a tracking system used on ships and by vessel traffic services (VTS) to identify and locate vessels through the exchange of electronic data with other nearby ships, AIS base stations, and satellites. This data includes unique identification, position, course, and speed, among other vital navigational information. Imagine the busy maritime corridors as highways […]
State Perspectives of AIS and Maritime Surveillance
AIS in Maritime Surveillance AIS technology works by automatically exchanging vessel data among ships and with terrestrial and satellite receivers. This exchange encompasses a variety of information critical to maritime surveillance, including vessel identity, position, course, and speed. The widespread adoption of AIS has transformed the maritime domain, providing a transparent and accessible view of […]
Mobile Applications for AIS Tracking and Data Analysis
AIS is a tracking system used aboard ships and by vessel traffic services (VTS) to identify and locate vessels. It accomplishes this by automatically exchanging data with other ships, AIS base stations, and satellites. This data includes unique identification, position, course, and speed, providing a comprehensive situational awareness to all parties involved in maritime navigation. […]
AIS Anomalies
An AIS anomaly occurs when the data transmitted by a vessel’s AIS device deviates from expected patterns or when the information is missing, incorrect, or suspicious. These anomalies can be subtle or obvious, but either way, they need careful attention to ensure they don’t lead to misunderstandings or unsafe situations at sea. Identifying AIS […]
AIS Voluntary Observing Ships Program
AIS is an automatic tracking system used on ships and by vessel traffic services. It provides information such as identification, position, speed, and course of ships, enhancing maritime safety and the protection of the environment. By broadcasting these details, AIS aids in avoiding vessel collisions and assists in the efficient navigation of crowded sea lanes. […]
How Navies Use AIS
AIS is an automatic tracking system that uses transponders on ships and is used by vessel traffic services. Ships equipped with AIS transceivers can automatically exchange data with other nearby ships, AIS base stations, and satellites, including information on identification, position, course, and speed, helping to avoid collisions and navigate safely. Navy ships, equipped with […]
Addressing AIS Spoofing and Jamming
AIS spoofing involves the deliberate transmission of fake AIS signals. These false signals can create nonexistent vessels on navigation displays or alter the perceived position, direction, or other navigational details of actual vessels. Besides posing a collision risk, they enable illicit activities by allowing vessels to obscure their true movements or identity. A relatively straightforward […]
AIS Assistance in Polar Expeditions and Shipping
The Role of AIS in Polar Regions The primary contribution of AIS in polar navigation is the enhancement of situational awareness. Given the limited visibility and unpredictable conditions characteristic of polar regions, being able to ascertain the presence, position, and intentions of nearby vessels is necessary. AIS provides this information, allowing ship operators to make […]
