Real-Time vessel & object monitoring by VHF

This system allows persistent locating and monitoring, of vessels and moving objects in a special area via VHF technologies. The vmsTRACK-PRO works with CSTDMA Class B transmission functionality. CSTDMA is the abbreviation for “Carrier Sense Time Division Multiple Access”, which is utilized in all AIS Class B units. This unit operates on the principle “listen before talk.” If a transmission is due, the transceiver watches the dedicated slot and if there is no transmission in the slot from a Class A transceiver, then the CSTDMA unit starts transmission on its own in this slot.

Palm-sized for every request

The vmsTRACK-PRO-CS is a small portable “grab’n’go” position transmitter, which broadcasts in a pre-set time interval via VHF radio frequencies. The unit is ideal for coastal fishing fleet, movement monitoring of harbour vessels, small target tracking, and pleasure boaters tracking. The system is expandable to a full target management system. With the usage of the vmsTRACK-PRO-CS real-time-tracking system, a radar-less traffic monitoring system for economic application is possible. By means of AIS transmission, information about current GPS position as well as course and speed over ground of the object, real-time-tracking and monitoring of  objects is possible for a base station

Geo fencing possible

Special areas can be programmed into the unit (not to enter or not to leave). They are called “Geo-Fence-Areas”. The vmsTRACK-PRO-CS unit gives visual alerting by flashing LED if this geofence-function is triggered and a special information message is immediately sent to the base station. Only the base station will be able to interpret this message.

Intelligent tamper-proof solution

If the unit is stolen or tampered, an intelligent high tech solution will trigger a flashing LED to inform the vessel’s Captain. A special message is also sent to the base station. This special message is sent within the normal position report, but only the base station can decode it

Individualization of vmsTRACK units

The vmsTRACK units can be individualized by means of programming ship name, type of vessel as well as area of activity into the unit for transmission. The pre-set time interval is free to define: each second up to 1 time per hour, everything is possible. The bigger the time gap is, the longer the battery capacity will be e.g.: once per minute will last for a couple of days. The power supply for the vmsTRACK unit on a small fishing vessel can be done by solar panel. This will continuously charge the transmitter. By transmission of special names and unit IDs, “friend or foe” identifying is possible

Power supply solutions possible

  • The vmsTRACK-PRO can be charged via its internal battery using the charging socket (A121)
  • Board net Fixed solution by means of connection to 9-32 VDC board net power supply. This will give permanent intelligent recharging (special modification of charging station on demand).
  • Solar panel Persistent external power supply with permanent intelligent recharging. This will be a fully self contained solution for permanent operation.

What is needed to run the vmsTRACK?

Each object going to be monitored needs a vmsTRACK-PRO. The charging station must provide intelligent and ideal charging to ensure the long lifespan of the batteries. The vmsTRACK is factory pre-set to a custom frequency for “closed user groups”.
