Abstract
There is described a system for translating clock domain for non-synchronized sensors comprising a first sensor, a second sensor, and an upstream device. The first and second sensors receive a beacon from a tag. Each sensor transmits a report including a beacon receive time in a sensor clock domain. The upstream device receives the reports and translates beacon receive times from the sensor clock domain to an aggregator clock domain. The translation is based, at least in part, on beacon reception data of the sensors, report transmission data of the sensors, and report reception data of the upstream device. The upstream device determines a location of the tag based on a delta of the beacon receive times in the aggregator clock domain.
