System and method to localise an entity

A system to locate an entity within an indoor environment comprising:

• one or more sensors communicatively coupled to the entity, wherein the one or more sensors comprises one of a plurality of inertial sensors and one or more radio frequency sensors, wherein the one or more sensors is configured to:
• sense data representative of a plurality of locations within the indoor environment;
• sense a plurality of data representative of a location of the entity within the indoor environment;
• a processing subsystem communicatively coupled to the one or more sensors, wherein the processing subsystem comprises:
• a raw data collection module configured to:
• generate raw data representative of a plurality of locations within the indoor environment based on the data sensed by the one or more sensors;
• create a floor map of the indoor environment based on the raw data generated;
• a computing module communicatively coupled to the raw data collection module, and configured to compare the plurality of data representative of the location of the entity within the indoor environment sensed by the corresponding one or more sensors with the raw data using a computing technique;
• and
• a location monitoring module communicatively coupled to the computing module, and configured to compute the location of the entity within the indoor environment based on a compared result in real time.
