14. AIS

AIS is an Automatic Identification System. It has been introduced to improve the safety of navigation by assisting in the efficient operation of ship-to-ship location reporting and VTS applications. The system should enable operators to obtain information from the ship automatically, requiring a minimum of involvement of ship’s personnel, and should have a high level of availability. AIS transponders installed on IMO vessels use VHF frequencies to:

·Transmit details of their own vessel

·Receive details from other vessels or navigation aids within VHF range.

Information being transmitted from vessels over 300 tons that, due to recent worldwide legislation, are required to fit Class “A” AIS transponders.

Connecting to the GPS Chart Plotter an AIS receiver (please contact your local dealer), will display vessels with AIS transponder within VHF range on screen giving the skipper or navigator a visual interpretation of the data of nearby vessels. This improves safety, and specifically for collision avoidance reasons.

14.0AIS SYSTEM DEFINITIONS

·Target: It is a vessel equipped with AIS. Information about the targets is being received by AIS Receiver and displayed on the screen.

·CPA : Closest Point of Approach is the closest distance that will be achieved between your vessel and the tracked target, based on your vessel’s speed and direction and the target’s speed and direction.

·CPA Limit: This is the distance from your vessel that a target may reach before a target is deemed a threat.

·CPA Alarm: Occurs if CPA is less or equal to CPA Limit. This test is done for active targets only.

·TCPA: Time to closest Point of Approach is the time remaining until the CPA will occur.

·TCPA Limit: This is the time remaining before the CPA is reached.

·TCPA Alarm: Occurs if TCPA is less or equal to TCPA Limit. This test is done for active targets only and if CPA value is less or equal to CPA Limit.

·Radio Call Sign: International call sign assigned to vessel, often used on voice radio.

·Name: Name of ship, 20 characters.

·MMSI: Maritime Mobile Service Identity.

·MMSI number: A unique 9 digit number that is assigned to a DSC radio station. It primarily registers the boat information in the U.S. Coast Guard’s national distress database for use in emergency situations.

·Active Target: Target located within the Activation Range. Active target is represented by oriented triangle with COG and Heading vectors. Rate of turn may also be displayed.

·Dangerous Target: Target detected by CPA or TCPA Alarm. Dangerous target is Active Target by definition. For better visibility Dangerous Target symbol is flashing.

·Sleeping Target: Target located outside the Activation Range. Sleeping target is represented by a small oriented triangle.

·Lost Target: When the AIS info is not received from that vessel for 3.5 minutes. The presentation will be a flashing black triangle with a cross through.

CPF180I, CPF300I specifications

The Standard Horizon CPF300i and CPF180i are two advanced marine chart plotters designed to enhance the navigation experience for both recreational and professional boaters. These units combine cutting-edge technology with user-friendly features, making them a popular choice among marine enthusiasts.

The Standard Horizon CPF300i is equipped with a bright 10.4-inch display that ensures excellent visibility even in direct sunlight. It features a high-resolution color screen that presents detailed cartographic information clearly. The unit integrates advanced GPS technology, providing precise positioning that is crucial for navigating complex waterways. Additionally, it comes with built-in Wi-Fi, enabling users to share their data and download updates easily.

One key feature of the CPF300i is its capability to support multiple chart formats, including C-MAP and Navionics. This flexibility allows users to select the cartography that best suits their needs, ensuring they have access to the most up-to-date navigational information available. The CPF300i also supports radar overlay and fish finder integration, making it an excellent tool for fishing and safe navigation in various conditions.

On the other hand, the CPF180i offers a slightly smaller 7-inch display but does not compromise on functionality. This model is perfect for smaller vessels, maintaining a compact form factor while delivering essential navigational features. The CPF180i also incorporates GPS functionality, ensuring accurate positioning and helping mariners stay on course. Its intuitive user interface allows for easy operation, making it accessible even to less experienced users.

Both models feature a built-in AIS (Automatic Identification System) that increases safety by displaying the positions of nearby vessels. The AIS integration allows users to monitor traffic in busy waterways and avoid potential collisions. Additionally, both units support NMEA 2000 connectivity, enabling integration with other onboard systems such as engine data and autopilot control.

In summary, the Standard Horizon CPF300i and CPF180i are equipped with high-resolution displays, robust GPS technology, and multiple chart support. The CPF300i, with its larger screen and advanced features, is ideal for those needing comprehensive navigation solutions, while the CPF180i caters to users looking for a compact and efficient unit. Together, they represent a significant advancement in marine navigation technology, providing boaters with the tools they need to enhance their on-water experience.
