Portable Local Positioning System

Systems, methods, and computer-readable media for mitigating collision occurrences on a drilling rig, of which an example of the method includes associating ultra wide band (UWB) tags with pieces of rig equipment and rig personnel. The tags are configured to communicate with one or more anchors. The method also includes determining interlock rules associated with each of the pieces of rig equipment, monitoring positions of the pieces of rig equipment and the rig personnel using the tags, in real-time, determining that one or more of the interlock rules are violated by a position of one or more of the pieces of rig equipment, rig personnel, or both, and, in response to determining that the one or more of the interlock rules are violated, at least partially disabling operation of one or more of the pieces of rig equipment. Associate tags with rig equipment and/ or rig personnel 502 Identify unsafe zones proximate to at least some of the rig equipment 504 Monitor relative positions of the rig equipment and the personnel in real time using the tags 506 ersonnel in Yes unsafe zone?
