1. A device of calculating seamless positioning, the device comprising:
a domain provided with a sensor for detecting a moving subject and configured to generate sensing data, the domain comprising:
a personal domain performed by a device that is carried by a moving user;
an IoT domain performed by a vehicle or an e-mobility service provider; and
an infrastructure domain performed by a public or private facility management organization, the infrastructure domain configured to transmit a location of infrastructure or surrounding traffic data;
a positioning domain configured to receive the sensing data from each of the personal domain, the IoT domain and the infrastructure domain and perform sensor fusion,
wherein the positioning domain generates a common message format for the sensor fusion,
wherein the sensor fusion is a combination of the sensing data from the personal domain, the IoT domain and the infrastructure domain, or a combination of the sensing data having a time difference generated by a single sensor of the personal domain, the IoT domain or the infrastructure domain;
wherein the common message format is identified by sensing data unit that is a unit of processing of the sensor fusion; and
the positioning domain processes the sensing data unit transmitted in time order.
