This is the same GNSS unit that comes in every Survey3 camera box. It uses a ublox UBX-G7020-KT chip inside to provide a quick location fix. When the camera has satellite lock it will beep 6 times.
The default cable is not as short as the photo shows, it will be about 40 inches (100cm) long. To have us shorten the cable please purchase this item as well.
This receiver only works with our Survey3 cameras.
