Systems, methods, apparatuses, and computer readable media are disclosed for improving, in some examples, reference in a location system. In one embodiment, a method is provided comprising: receiving reference tag blink data from a plurality of receivers; calculating, using a processor, a reference phase offset between the plurality of receivers; and generating a suspended reference phase offset table, 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.
