Frequently Asked Questions about Marine AIS Products

The cost of an Automatic Identification System (AIS) can vary significantly based on the type of system, its features, and the manufacturer. A basic Class B AIS transceiver, typically used on smaller vessels or by recreational boaters, can range from $500 to $1000. A more sophisticated Class A AIS, compulsory for larger commercial vessels, can be considerably more expensive, with prices ranging from $2000 to more than $3000. Additional costs could include installation fees, external antennas, or integration with existing navigation systems. If a vessel requires a display or a system with advanced functionalities such as integrated electronic chart systems, the cost can also increase. Moreover, choosing between standalone AIS units and those that are part of multifunctional display systems can impact the overall expense. It's wise for buyers to also consider potential subscription fees for AIS services that offer enhanced features.
The difference between Class A and Class B AIS revolves around their intended use, transmission power, and functionality. Class A AIS is designed for commercial ships such as cargo vessels and tankers and is mandatory under international maritime regulations for all vessels over 300 gross tonnage operating internationally. Class A units transmit at a higher power (12.5 watts), which allows them to be detected over greater distances. They also update their position and vessel information more frequently (every 2 to 10 seconds when moving and every 3 minutes when at anchor). Class A devices feature a more robust set of functionalities including a display screen, a wider array of sensors, and more comprehensive navigational data. Class B AIS is typically used by smaller, non-commercial vessels such as pleasure crafts, fishing boats, and yachts. They transmit at a lower power (2 watts) and less frequently than Class A (every 30 seconds when underway at high speeds and every 3 minutes when at lower speeds or at anchor). They may have fewer features and simpler interfaces but are also more cost-effective and easier to install.
GPS (Global Positioning System) and AIS (Automatic Identification System) are distinct technologies with different primary functions. GPS is a satellite-based navigation system that provides users with their precise location (latitude and longitude), navigation, and timing services globally. It is a passive system that receives signals from a constellation of satellites to determine a receiver’s exact position on or near the Earth. GPS is used across various applications beyond maritime and is not specific to vessel tracking. AIS, on the other hand, is a maritime navigation aid that uses VHF radio frequencies to send and receive ship information, such as identity, position, course, and speed, to enhance collision avoidance. While AIS relies on GPS for position data, it is an active system that communicates this position along with other vessel-specific information to nearby ships and tracking stations. GPS tells you where you are, while AIS tells others where you are and provides you with information about them. Both are critical in modern navigation, but they operate independently of each other.
