Radio Direction Finders and Direction Finding Systems

Networking Direction Finders

There are a number of ways to network both fixed and mobile MPT direction finders.  Where an Ethernet type infrastructure exists, multiple DFs can be networked to one or more control sites running our latest software program TargetTrack. This can even include mobile DFs if a cellular network covers the tracking area. All of the configurations shown below adapt to this type of network by simply inserting the network interface modems along the connection labeled Ethernet.

Doppler Direction Finding Network using Ethernet

Where an Ethernet infrastructure does not exist a VHF or UHF radio modem system can be used. This is a multiplexed type of system where all sites are allocated a time slot for sending data. The physical interface to the DFs is through one of the USB ports using a serial converter if required by the radio modem. So no laptop or PC is required at the remote sites; however, a laptop can be used at the remote or mobile site if it is desired to have an operator.

 Doppler Direction Finder Networking using Radio Modems

It is possible to mix the networking interfaces so that some remote sites communicate via the Ethernet connection and some sites communicate via a radio modem.  The TargetTrack software supports our older DDF6001 and DDF6002 direction finders so these devices can be used on the network as well.
