Environmental Monitoring Stations

Yes. The AWOS-AV system is FAA-certified and complies with FAR 91.171 and FAR 91.175 standards, as well as ICAO requirements. It is specifically designed for airports and private helipads requiring official automated weather observation for air traffic control and flight operations. The MAWOS system is also available in a non-FAA-certified configuration for broader applications.

OSI stations measure a comprehensive set of atmospheric parameters including wind speed and direction, temperature, relative humidity, barometric pressure, dew point, visibility, precipitation type and rate, and present weather conditions such as rain, snow, drizzle, freezing precipitation, and mixed conditions. Specific parameters vary by station model and configuration.

Yes. The OWI-432 WIVIS and MAWOS stations support flexible power configurations including standard AC, battery, and solar panel options, making them suitable for remote, unattended, and off-grid deployments. The HazMet-100 is also low-power and solar/battery compatible for rapid field deployment anywhere without infrastructure.

The HazMet-100 is engineered for rapid deployment and can be fully set up and transmitting atmospheric data to EPA's ALOHA dispersion modeling program in less than 5 minutes, with no tools required. Its built-in GPS and electronic compass eliminate the need to manually orient the wind sensor, further reducing setup time during time-critical hazmat incidents.

OSI stations are designed for ultra-low maintenance. With no moving parts and no temperature-sensitive analog components, there is no scheduled cleaning of optics required and the systems are insensitive to dirt buildup. The MAWOS system has an MTBF exceeding 80,000 hours and includes built-in continuous self-test and self-diagnostics for ongoing performance monitoring.

OSI monitoring stations support a range of communication interfaces including RS-232 (standard), RS-485, Ethernet, limited distance modems, and optional cellular modems. Additional options include spread spectrum radios, satellite, and GSM connectivity. Data is output as ASCII strings (polled or unpolled) and MODBUS RTU over serial RS-232, with METAR-format reports available on aviation systems.
