Nanjing LES Information Technology Corporation (LES) is a high-technology specialist.
We are a worldwide market leader in the design, research and development (R&D), installation and integration of large-scale electronics systems, which focuses in air traffic control (ATC) industry.
More than 200 systems and terminals have been deployed in national and international airports, such as:
With experience in the design and manufacturing of ATC systems for civil and military applications, LES provides high-performance solutions suitable for tower control, approach control, en-route control and area control.
Our master/backup system includes:
Its main functions consist of:
LES’s training system provides the controller with a simulation platform implementing procedure control and radar control.
It is used for the training of control skills, operation procedures and control rules via the following:
Typical features include:
All training-related factors, such as airport environments and air traffic situations, can be simulated for controller training. These include accidents and special scenarios, such as bad weather (heavy rain, fog and sandstorms). The system connects with area control and approaches radar simulation systems to form lifelike training methods.
With its scalable and tailored capabilities, LES’s A-SMGCS provides airports with seamless gate-to-gate connection and improved control efficiency.
It has been successfully applied in various airports, such as Beijing, Shanghai, Hangzhou and Nanjing International Airports.
The A-SMGCS can perform the following operations:
LES supplies a multi-channel voice communication system for air traffic control applications. It simultaneously implements radio, telephone, intercommunications and public address via a configurable touchscreen interface.
Our VCCS system also implements the latest user interface technology, using colour touch-panels and editing tools for customised user interfaces.
Main features:
Composed of multiple ground stations, LES’s MLAT-01 system receives signals from an aircraft and calculates its position, according to the received signals’ time difference of arrival (TDOA). The MLAT-01 is also used to enhance the surveillance capabilities of airport surface and area.
The MGC-01 ADS-B ground station is a high-performance tool used for airport, en-route and area surveillance. It is an effective and economic replacement for surveillance radar and complies with the 1090 ES and user acceptance testing (UAT) standards.
Established in 1988, LES is China’s largest ATC system specialist with more than 30 years’ experience. All of our systems are built according to the International Civil Aviation Organization (ICAO) standards.
We are China’s national ATC system global design unit and the leading ATC system provider for the Civil Aviation Administration of China.
