IMS4 RVR Runway Visual Range System The IMS4 Runway Visual Range system performs the automated runway visual range assessment and reporting to the airports. Available 24 hours 365 days a year ICAO Forward scatter technology ICAO compliant with CAT I - III AWOS AWDSS Standalone system or integrated within AWOS / AWDSS Multiple sensor interfaces Real time data processing Field sensors The typical set of IMS4 RVR field measurement system consists of forward scatters, background luminance sensors as well as interfaces to runway lights systems. Multiple types of sensors and communication interfaces are supported. The data processing software enables any standard or nonstandard combination of sensor positions along the runways, hot backup of the sensor values and manual data entry. For each sensor type, the evaluation and visualization of the sensor status as well as remote maintenance is provided. 1

MicroSteo IMS4 RVR server Standard COTS Intel based server or a dual hot failover cluster, the IMS4 RVR server collects the visibility, background luminance and runway lights intensity data from the field measurement system, calculates the RVR, distributes the data to displays as well as 3rd party systems; it also provides operators with alerts related to the significant thresholds of the visibility and / or RVR. In case of the integration of the RVR system into AWOS, the RVR values are displayed on the local as well as remote AWOS screens, are imported into METAR / SPECI and local routine or...
