WINDEX-300

The WINDEX-300 Lidar Wind Profiler is designed to provide remote measurement of wind speed and direction at specified altitudes. WINDEX-300 is a core component of the first Russian Low-Level Wind Shear Alerting System.

ADVERTISING BOOKLET

WINDEX-300 is developed in accordance with the requirements of State Standard and Sanitary Rules and Regulations and refers to safe laser products. If a dangerous wind shear is detected, the system transmits corresponding messages to all air navigation users. 

The Low-Level Wind Shear Alerting System is intended to:

  • Promptly and remotely determine and display information about the vector direction and the magnitude of an airflow at specified altitudes;
  • Identify low-level wind shear and turbulence;
  • Promptly alert all air traffic participants to low-level wind shear and turbulence.

EFFICIENTLY SOLVES THE FOLLOWING TASKS:

WINDEX-300 is capable of detecting:

  • Vertical wind speed component;
  • Horizontal wind speed component;
  • Headwind and tailwind components with regard to designated objects;


  • Vertical wind shear at the along-wind component with regard to the runway direction or other objects;
  • Wind speed direction with regard to the direction to the north. 

WINDEX-300 APPLIES TO THE FOLLOWING FIELDS:

Airports

Heliports, airfields

Control of atmospheric stability.

Aeroacrobatics

Aerobatics

WINDEX-300 is certified by the Federal Agency on Technical Regulating and Metrology and has the Pattern Approval Certificate of Measuring Instruments issued by IAC. WINDEX-300 is developed in accordance with the requirements of State Standard and Sanitary Rules and Regulations. The profiler is eye-safe and this parameter is certified by the Russian Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing's submission and by the audit. 


WINDEX-300 passed certification tests on the Obninsk Meteorological Tower. During the tests the WINDEX-300 measurement data were compared with anemometers installed at different tower heights and metrological characteristics on the aerodynamic tunnel of the State Special Standard of Air Velocity were examined (St. Petersburg). In addition, WINDEX-300 passed the all-season operational testing at the Pulkovo Airport (St. Petersburg).
