Our RadioFrequency beacon system, also known as "Rockwell lBeacon", help you find lost drone up to distance 8 km .
Only 12 gram weight, 2 month autonomous work time and full "RF silent mode while flying" (it is NO GPS tracker, who have unpredictable strong rf emission! ).
The RF beacon easy connect to NAZA-M GPS receiver (also Phantom 1 and 2)  via special cable , and transfer "last known" coordinates to the searching device only if you need this.
Also you can find RF beacon without coordinates, just go to for strong rf power, who displayed on the search device.
The search device have Bluetooth interface, who can transfer coordinate to the map on Android smartphone or notebook.

how to install it on  DJI phantom 3,  or inspire 1 ?  

Thanks
