Doppler Systems offers a rack mounted solution for fixed site radio direction finder (RDF) installations.  The rack mount solution includes a direction finding processor, a wide band FM receiver, a GPS receiver, an Ethernet interface, and an optional self-test generator.  The direction finder works with any of our fixed site antenna arrays.  It can be directly connected to your network or can be accessed over the Internet using VPN or port forwarding on your router.  Configurations are availble to monitor multiple frequencies simultaneously using a single antenna.  Contact us to help you configure a solution that is right for your application.
