Real-Time vessel & object monitoring by VHF
The system allows persistent locating and monitoring of vessels and moving objects in a special area via VHF technologies. The vmsTRACK-PRO-CS is working with CSTDMA Class B transmission functionality. CSTDMA is the abbreviation for “Carrier Sense Time Division Multiple Access”, which is used for AIS Class B units. The vmsTRACK-PRO-CS 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. It is suitable for fishermen, vessels, leisure boats, ski jets, harbour crafts, pilot vessels, etc. 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 the transmission, information about current GPS position as well as curse and speed over ground of the object, real-time-tracking and monitoring of objects is possible for a base station. Such a base station only needs a special tuned receiver unit to get these position reports, if customized frequencies are used. The creation of a “closed user group” is possible with such a system, in which only the base station has the permission to look into, thanks to these customized frequencies. The vmsTRACK-PRO-CS is also able to run on regular AIS frequencies which makes a special tuned receiver needless.
