This is the same GPS unit that comes in every Survey3 camera box. It uses a ublox UBX-G7020-KT chip inside to provide a quick GPS fix. When the camera has satellite lock it will beep 6 times.
Since this GPS receiver does not have a barometer it is still possible for the altitude values to be captured incorrectly, so some post processing may be required.
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 the Survey3 cameras, not Kernel, Survey2 or Survey1.
