Sentinel: What if the GNSS antenna status indicates a fault?

In some circumstances, Sentinel may erroneously indicate a fault with the GNSS antenna. This can occur when the antenna is not powered by Sentinel - i.e. a splitter is connected in-between the antenna and Sentinel. 

The GNSS module checks for open and short circuits on the feed of the antenna and will flag an issue if it believes it is not in a healthy state. In this scenario, a fault being displayed will likely have no impact on the system.

The key indicator is whether satellites are detected correctly, the survey completes, and Sentinel indicates a suitable number of locked satellites with good SNR.

If no satellites are detected and the survey doesn’t complete then the antenna installation should be investigated.
