Support for mixed networks of RFeye Node 100-x and Node 50-8 for TDOA was a new feature in RFeye Site version 1.48.2.44. This version includes Node 40-8.
There are two key features in this release. First, is the addition to display a synthetic vector (line of bearing) to indicate the direction of a signal if an accurate geolocation is not possible. This can be extremely useful when detecting and geolocating low-powered signals such as those emitted by drones. The second key feature is the ability to create a complex mission within RFeye Site and then export that configuration into Mission Manager so it can be run on an automated, scheduled basis. This is called a Mission Automation Configuration (MAC) file.
More about these features can be found in our blog.
