About “TRIHAWK V650series”
The “TRIHAWK V650 Series” is the JRC standard type of VTS system capable of a medium to large scale of sea area surveillance. This system can integrate the data from 3 radar stations to monitor vessel movements in a wide sea area (100NM). This series can be designed for the Basic and Standard System in accordance with IALA-128.
The purpose of vessel traffic service is to improve the safety and efficiency of vessel traffic and to protect the environment.
One of the main functions to attain the purpose of VTS is the function of monitoring vessel movements, by which the positions and movements of a number of vessels navigating in the water areas within the multi-radar coverage can be monitored and presented on an electronic chart display screen. Using this function, the VTS operator can transmit proper messages to each vessel and accurate information to various organizations related to ports and routes.
For instance, if a vessel is sailing toward a shallow water area, the operator can foresee a risk of grounding in monitoring the VTS screen. In this case, the VTS operator can call to the vessel via the international VHF communication system (as he can recognize the vessel’s name by AIS) and advise the vessel of its risk of grounding by allowing the vessel to have a chance of turning the rudder to avoid the danger of grounding. Thus, the potential impact of such grounding on the sea environment and a resulting economic loss can be prevented. In addition to such risk of grounding, the VTMS allows various alert operations to prevent vessels from various risks such as collisions of vessels, intrusion into a restricted water area, and intrusion of a suspected vessel to a guarded area.
The radar information from up to 3 radar stations can be integrated and tracked on the VTS screen. This function allows the seamless surveillance of a wider sea area. A shadow area which a single radar station cannot detect can also be monitored by the multi-radar integrated system.
Each radar antenna is selectable from a lineup of 9-foot (2-unit), 9-foot (3-unit), 18-foot (3-unit) horizontal and 18-foot(3-unit) circular types, and the X-band transmitter/ receiver system is available in the conventional magnetron type and the solid-state type, allowing the optimum system configuration to meet the purpose of use and the sea water coverage.

The Image Server/Tracker provides high resolution radar image processing and high tracking performance. The tracking of the target echo entering in the pre-set area or crossing the line setting by the user on the Operation Display is automatically started and the tracking of only selected target echo(es) by manual is (are) also available. The stationed buoy or rocks such as not expecting vessel are able to exclude a tracking target.
This VTS system is provided with various alarm functions to prevent vessel collision accidents and keep the safety and security at sea areas.
If pre-setting alarm conditions are satisfied, the alarm sound is automatically generated and inform to the operator. Pre-setting alarms are as follows;
The information on the Operation Display and tracking target in formation are automatically recorded (recording period can be selected by the user) and are able to replay on the Operation Display with a playback software. Automatic recording is functioned during the playback operation simultaneously.
This function allows the status analysis to be made in event of accident occurrence and the sea area management system to be improved.
AIS information can be integrated on the Operation Display. If the radar target echo and the AIS target vessel are identified, those are automatically integrated and displayed on the screen with a single symbol.
The VTS system can select the function of AIS base Station and send own station data to other stations.
By integrating the radar system with a CCTV (closed circuit television) camera, the system can control the camera to direct to a target echo on the radar monitor of the Operation Display. The system can also control the CCTV camera to track a target echo based on the radar track information or to automatically track a vessel which enters a security area. Therefore, the actual movement of the vessel can be monitored on the CCTV monitor using the symbol indicated on the radar monitor.
Up to 5 Operation Displays can be installed optionally, allowing two or more VTS operators to monitor sea water areas. By selecting optional displays, up to 3 screens ca n be connected to one Operation Display Unit. The 3 display screens can present 3 different displays individually or one integrated water area as a single screen, allowing flexible screen configuration.

All target tracked data from the radar data processor (from all radar stations) and AIS target information from the base station will be transferred to a multi-sensor integrated processor. This rock-solid processor provides the performance, stability and security a control center requires. The following features are especially important for effective traffic monitoring:
The AIS base station is a broadcast communication system, operating in the VHF maritime frequency band, and is capable of automatic vessel information data transmission to other neighbouring vessel’s and to the operation center ashore.
Information transferred includes identification, position, course, speed, and ship’s dimensions, draught, type and cargo information. The AIS base station is fully compliant with international UAIS performance standards. It reduces VHF communication and improves target tracking, especially during bad weather conditions.
Closed Circuit Television (CCTV) integration is an important enhancement to the daily operation. The camera system allows pan, tilt, zoom and it has wiper functionality. It can be remotely controlled and can automatic acquisition targets, all simply via the operator console.
JRC’s dual-25kW X-band transmitter/receiver has the advantage that it can be easily installed and maintained, due to a simplified mechanical construction design. A solid state construction is adapted to the electronic circuit blocks allowing for a highly reliable operational performance. The amplifier, included in the receiver, uses a so-called logarithmic amplification so that unnecessary sea and rain clutter restraining the radar video signal can be easily suppressed in the system operation, which allows for improved radar observation.
