GPS Device Setup

Connect GPS Devices and Layers using Gravio Studio

In Gravio, GPS devices (GPS devices available via COM port connection) can be used as data input devices as a single layer. Please refer to this link for GPS devices that have been confirmed to work.

Confirming GPS Device Connection

For Windows 10, confirm that COMx (in this case COM5) is displayed in the Device Manager to verify the GPS device connection.
