Tactical Meteorological Station Systems
Military Ballistic Weather Station
The Military Ballistic Weather Station is designed to accurately measure environmental data such as wind, temperature, pressure, and humidity required for ballistic calculations. It can also detect rain and cloudy weather conditions and transmits all acquired data to the user in real time. Built for reliable operation under demanding field conditions, the system provides real-time meteorological data for artillery, mortar, and fire-control applications. Its dual-antenna GNSS technology enables highly accurate position and velocity tracking, and because heading is derived from satellite positioning rather than a magnetic compass, direction finding remains unaffected by nearby metal. Its rapid-deployment capability supports improved targeting accuracy and operational effectiveness.

Technical Documents
The Military Meteorological and Ballistic Data Station is a modular plug-and-play sensor station that provides real-time meteorological measurements to optimize the accuracy of indirect-fire weapons. It combines an ultrasonic anemometer, a digital barometer, a temperature/humidity sensor, GPS, and an onboard processing unit on a single ruggedized platform. Collected data is transmitted to the fire direction system in the standard NATO artillery format (STANAG 4082 METCM/METB) or a project-specific protocol, forming the first link in the ballistic computation chain.
Why It Matters
For indirect-fire and precision-shooting systems, meteorology is the single largest variable driving accuracy error:
- 155 mm howitzer, 25 km range: 30 km/h crosswind → approximately 40 m deflection
- 12.7 mm precision rifle, 1500 m: 15 km/h crosswind → approximately 25–30 cm deflection
- 120 mm mortar, 8 km: a 10 °C temperature difference → range shift of ~50 m
- Guided munition launch: air density directly affects thrust performance
Without accurate real-time MET data, these variables are compensated only through tabular estimates, resulting in reduced accuracy and higher ammunition expenditure.

Measurement Principle
The ultrasonic anemometer offers three advantages over conventional cup or vane anemometers: no moving mechanical parts (minimizing failure risk), continued operation under icing and freezing conditions, and accurate readings even at very low wind speeds. Temperature and humidity sensors sit inside a solar radiation shield; the barometer is internal and auto-corrects to the local altitude reference.

Applications
- 105 mm and 155 mm artillery battalion/battery meteorological station
- Mortar batteries (60 mm, 81 mm, 120 mm)
- MLRS and rocket launcher fire direction
- Long-range sniper teams
- ATGM and guided munition support meteorology

Integration
The system integrates directly with standard fire control software and vehicle battle management systems (BMS); its STANAG 4082 output is compatible with most NATO-standard artillery fire direction packages. It can be deployed in tripod (portable), mast-mounted (fixed battalion position) or fixed-tower (garrison/facility) configurations.
