1. A system, comprising:
a head worn display configured to display symbology of an operating environment;
a tracking camera;
a tracking processing unit communicatively coupled to the tracking camera configured to:
determine a position and orientation of the head worn display; and
transmit a position and orientation signal to a controller, wherein the position and orientation signal includes a signal quality value; and
the controller communicatively coupled to the head worn display and the tracking camera comprising:
one or more processors; and
a memory with instructions stored upon, that when executed by the one or more processors, cause the one or more processors to:
display the symbology on the head worn display;
determine a quality-of-service value based on at least the signal quality value; and
modify, graphically, at least one symbol of the symbology based on the quality-of-service value from a default symbol to a degraded symbol if based on the quality-of-service value changing from a high-quality value to a low-quality value.
