Tender Location System
Our Tender Location System or Tender Tracking System (TLS) module allows for identification and localisation of vessels in small fleets.

Furthermore it is possible to exchange customspecific data like depth and water temperature. This additinal data may be displayed in an electronic chart (ECDIS).

The basic TLS version incorporates two independent NMEA ports and may receive and forward nearly unlimited data sentences.

Unlike AIS the navtec TLS is paparazzi proof due to ciphering.

The basic system transmits GPS-Position and depth.

Customspecific requirements may be implemented.



Tender Location
                    System / tender tracking system
ECDIS
                example
  • The navtec TLS can be attached to all ECDIS Systems.
  • It generates a variety of data formats including AIS compatible data sentences.
  • Custom specific modifications can be implemented on request.
TLS Jet-Ski The navtec Tender Location System (TLS) comes in a waterproof (IP-56) housing.

LEDs monitor the system status all the time.

The navtec TLS can be equipped with a built-in rechargeable battery for uindependant Jet-Ski use.

Depending on TLS version three or four plugs connect the TLS to the ships electronic.
  1. Typ-N VHF/UHF antenna /RX/TX)
  2. Typ-N GPS antenna (input)
  3. Typ ESTO NMEA input
  4. Typ ESTO external power
