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 is a small portable position transmitter, which broadcasts in a pre-set time interval via VHF radio. By means of the transmission contained information about current position as well as curse and speed over ground of the object, persistent real-time-tracking and monitoring is possible for a base station. Such a base station only needs a special tuned receiver unit to get these position reports. Creation of a so called “closed user group” is possible with this system, in which only the base station has the permission to look into.

Geo-Fence

Special areas can be programmed into the unit where not to enter or not to leave. So called “Geo-Fence-Areas”.

Intelligent tamper-proof solution

If the unit will be stolen or tampered, an intelligent high tech solution will trigger a flashing LED to inform the vessels Captain as well as a special information message is send to base station immediately.

Transmission will run according to the world wide standardized AIS system (Automatic Identification System), but on special proprietary frequencies which are not used for AIS. The regular AIS radio traffic will be not disturbed or interfered by the position reports of the vmsTRACK units.

“Who and Where” for coastal security and fleet management

The real-time-knowledge of “who and where?” is very important in administration of coastal fishing fleets as well as in coastal boarder security issues. By transmission of special names and unit IDs “friend or foe” identifying is possible.

Additional emergency distress button

The small vmsTRACK has got an additional emergency distress button. By triggering the alert function, additional to the regular position report on special frequency, according to customer’s specification and with approval of the national authority, an official emergency message will be send out on both regular AIS frequencies to reach every AIS receiver within transmission range of the vmsTRACK.

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. As bigger the time gap is, as 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 realized by solar panel. This will continuously charge the transmitter.

What is needed to run the vmsTRACK?

Each object going to be monitored needs a vmsTRACK. The charging station provides intelligent and ideal charging which ensures the long lifespan of the batteries.

For monitoring all the moving objects in your special area you only need the easyTRX2 Receiver as well as a terminal to display the incoming position reports.

Other VHF receiver will not work with the vmsTRACK.

The vmsTRACK is factory preset to a custom frequency for “closed user groups”.

  • Transmission power: >= 3 W (usually for objects)
  • Specifiable frequency range from 155.450 MHz to 162.025 MHz,
    25 kHz channel spacing
    (Please ask your local authority for costumer frequencies.)
  • Operating temperature range:
    -10 °C to +65 °C
  • Storage temperature range:
    -30 °C to +65 °C
  • charging temperature 0° C to + 45° C
  • Dimensions
    (L x W x H): 130 x 70 x 30 mm
  • Weight: 250 g
  • A121 Charging station (quantity and type depends on the customer requirement).
    Other charging stations cannot be used!
  • Portable easyINFOBOX with a customized receiver and a terminal device
  • Customized receiver to connect it to customary display devices
  • PC software to display the data
  • Solar Panel Power Supply
