Radio Detection Finders (RDF) are used to home in on a specific radio frequency source and provide Lines of Position (LOP) to help locate the position of a vessel through the use of one or more detection stations. Typically these are used in Search and Rescue (SAR) missions where vessels in distress need to be located, their positions verified, or to locate a source of communication.

When SAR personnel receive an alarm by radio, satellite telephone or Cospas-Sarsat signals, precisely locating the individuals in distress represents the biggest problem. Darkness or poor visibility conditions can prolong rescue activities or even make such activities impossible. The faster the recovery is completed, the greater the chances of survival of the victim, especially in cold water. Speed is what determines whether a rescue mission is a success or a failure.

Our Radio Direction Finder is based on multi-channel architecture provides fast and accurate signal measurements for critical safety-related applications. It can be easily integrated into the Command and Control or VTS systems for search and rescue operations and radio band protection applications.

The RDF system can be networked together on land and /or on rescue craft to identify the line of bearing (LOB) or source location of distress signals or other RF transmissions. Client software provides an easy-to-use interface for monitoring and locating the position of RF transmissions. The output from the RDF system is interfaced into the Command and Control system.
