Cellular field testing automation tool: automation of emergency location accuracy improvements

A system comprising:

• a physical computing processor;
• and
• a non-transitory computer-readable medium encoding instructions that, when executed by the physical computing processor, cause the physical computing processor to perform operations comprising:
• detecting, by a cellular field testing tool in response to a device under test making an emergency call, multiple location data structures that each provide respective indications of a location of the device under test;
• selecting, by the cellular field testing tool, a comparison location data structure from the multiple location data structures by applying a selection policy to the multiple location data structures;
• comparing, by the cellular field testing tool, the comparison location data structure to an identification of a location of the device under test according to a ground truth database;
• and
• outputting, by the cellular field testing tool, an indication of whether the device under test passes or fails a corresponding performance test based on comparing the comparison location data structure to the identification of the location of the device under test according to the ground truth database;
• wherein:
• the selection policy selects the comparison location data structure at least in part by comparing an indication of horizontal and vertical uncertainty for the comparison location data structure with an indication of horizontal and vertical uncertainty for a distinct data structure within the multiple location data structures.

A non-transitory computer-readable medium encoding instructions that, when executed by at least one physical processor of a computing device, cause the computing device to perform operations comprising:
