Purpose: To understand the grounding of an Inertial Labs device with a GNSS receiver and to understand the configuration of the TNC antenna cable shield.
Last Updated: July 2020
The shield of the TNC antenna cable is connected to the chassis of the device, and on the GNSS receiver this shield is connected to the power return potential. Since that is the case, the whole enclosure is under the same potential. We recommend users to isolate the chassis from the power return potential if it is required in their application, as we have not had any problems related to chassis isolation in any application.
