Method, apparatus, and computer program product for real time location system referencing in physically and radio frequency challenged environments

An apparatus comprising a processor and a memory including computer program code, the memory and computer program code configured to, with the processor, cause the apparatus to:

• receive reference tag blink data from a plurality of receivers;
• calculate a reference phase offset between the plurality of receivers;
• analyze a plurality of reference phase offset calculations for at least one reference tag receiver pair over a time interval;
• and
• generate a suspended reference phase offset table in an instance in which the plurality of reference phase offset calculations for the at least one reference tag receiver pair satisfy a stability threshold, wherein a suspended reference phase offset table is generated by causing the reference phase offset to be stored in a memory for later tag location calculations.

A computer program product comprising a non-transitory computer readable medium having program code portions stored thereon, the program code portions configured, upon execution to:

• receive reference tag blink data from a plurality of receivers;
• calculate a reference phase offset between the plurality of receivers;
• analyze a plurality of reference phase offset calculations for at least one reference tag receiver pair over a time interval;
• and
• generate a suspended reference phase offset table in an instance in which the plurality of reference phase offset calculations for the at least one reference tag receiver pair satisfy a stability threshold, wherein a suspended reference phase offset table is generated by causing the reference phase offset to be stored in a memory for later tag location calculations.
