LGS, Latvia Awards Contract to FREQUENTIS for Implementation of ATC Information Display System

Latvijas Gaisa Satiksme (LGS) based at Riga International Airport in Latvia has been operating an ATC Information Display system that was developed in-house in 2000.
The system has provided timely information about NOTAN and OPMET data to LGS Air Traffic Controllers and other operational personnel. The existing system is approaching the end of its life and a replacement was sought that would both support existing capabilities and would take advantage of new hardware technology, principally larger flat screen displays, and would offer capacity and performance enhancements.

After a thorough evaluation of the systems available on the market, LGS awarded the contract to Frequentis to provide a replacement system based on the proven technology of the Frequentis NOTAM and OPMET data management applications. The system is due for deployment in 2013 and for going operational early 2014.

The basic operational concept is to display OPMET and NOTAM information specific to the tasks performed by each controller on a large screen. The screen requires little or no input from the Air Traffic Controller for normal use and yet it is easily adaptable by the controller for non-standard operational situations.

Each screen will display multiple windows of information consisting of selected OPMET reports, selected NOTAM and OPMET graphics. A default configuration of data and windows will be configured for each operational position or operator. Normally, the user will find all required information displayed in a familiar arrangement. However, to adjust the visible data the display is equipped with a mouse or optionally for touch screen control by the operator. A few clicks or gestures by the operator can add new windows, data types, and reporting locations selected from predefined list of available data and locations. The mouse can open and close data windows, resize and move windows, and, in general, adjust the screen to meet the immediate needs of the controller.

One critical feature of the system is the identification of changes to displayed data. Whenever, the data on display is updated, the controller is alerted by the specific report or graphic being highlighted until acknowledged by the operator. Optionally, an audible alarm can be initiated.

A Supervisory Terminal is an integral part of the system. It will be used for setting up the default configuration for each operational position or controller, define valid users, and to monitor and log all operational events performed at the terminal.

Frequentis and LGS have successfully collaborated on a number of projects in the past and we are confident that Frequentis will be successful in implementing a modern and user friendly Information System critical for the daily operations of our Air Traffic Controllers said David Taurins, CEO at LGS.
