The connected object possesses a wireless receiver for receiving signals coming from a plurality of located terminals. The signals include location data for locating the located terminals. The connected object calculates a piece of geolocation information of its own position based on a plurality of location data coming from the various located terminals. ## Claims ### Claim 1 A connected object which comprises: a wireless receiver, which is configured to receive signals originating from a plurality of located terminals, said signals comprising location data for locating said located terminals; a processor configured to: calculate a geolocation information item in respect of a position of the connected object on the basis of a plurality of the location data originating from different ones of the plurality of located terminals, determine a precision datum associated with the calculated geolocation information item, a value of this precision datum taking into account a number of occurrences of location data used for the calculation of the geolocation information item, and periodically activate and deactivate the wireless receiver and the calculation of the geolocation item, wherein a frequency of activating the wireless receiver evolves in a manner inversely proportional to the value of the precision datum; and an emitter, which is configured to emit the precision datum and the geolocation information item. ### Claim 2 (depends on 1) The connected object as claimed in claim 1, wherein each of said signals furthermore comprises a datum representative of power of the signal emitted by the respective located terminal, the processor determining a distance between the connected object and the respective located terminal as a function of the received power datum and of an amplitude of the signal measured on reception, the processor determining the connected object's geolocation information item by using the distances with the plurality of located terminals. ### Claim 3 (depends on 2) The connected object as claimed in claim 2, wherein the precision datum determined by the processor depends on the number of occurrences of location data having served to determine distances between the connected object and the located terminals and which have been used for the calculation of the object's geolocation information item. ### Claim 4 (depends on 1) The connected object as claimed in claim 1, wherein the location data are transmitted by the located terminals, each in a packet comprising an identifier present in a header, and the processor is configured to activate the calculating during reception of the identifier so as to process the location data contained in a body of the packet. ### Claim 5 (depends on 1) The connected object as claimed in claim 1, wherein the connected object has a memory for storing a succession of geolocation information items determined by the processor, and said processor is further configured to determine that the connected object is in motion when at least two consecutive geolocation information items are mutually offset geographically by at least a predefined distance. ### Claim 6 (depends on 5) The connected object as claimed in claim 5, wherein the connected object comprises a motion detector configured to increase a frequency of activation of the receiver and the calculation during detection of a motion of the connected object. ### Claim 7 A method for geolocating a connected object furnished with a wireless receiver, wherein the method comprises: receiving by the object signals originating from a plurality of located terminals, said signals comprising location data for locating said located terminals, calculating within the object a geolocation information item in respect of a position of the object by using as input data at least one plurality of location data originating from different ones of the located terminals; calculating within the object a precision datum associated with the geolocation information item by taking into account a number of occurrences of the location data used for the calculation of the geolocation information item; the object periodically activating and deactivating the wireless receiver and the calculating of the geolocation item, wherein a frequency of activating the wireless receiver evolves in a manner inversely proportional to the value of the precision datum; the object periodically activating and deactivating the wireless receiver and the calculation of the geolocation item, wherein a frequency of activating the wireless receiver evolves in a manner inversely proportional to the value of the precision datum; and emitting by the connected object the geolocation information item and the precision datum. ### Claim 8 A non-transitory computer-readable medium comprising a computer program product stored thereon comprising program code instructions for execution of a method of geolocating a connected object when said program is executed on a central unit of the connected object, wherein the program code instructions configure the connected object to: receive, by a wireless receiver of the connected object, signals originating from a plurality of located terminals, said signals comprising location data for locating said located terminals, calculate within the object a geolocation information item in respect of a position of the object by using as input data at least one plurality of location data originating from different ones of the located terminals; calculate a precision datum associated with the geolocation information item by taking into account a number of occurrences of the location data used for the calculation of the geolocation information item; periodically activate and deactivate the wireless receiver and the calculation of the geolocation item, wherein a frequency of activating the wireless receiver evolves in a manner inversely proportional to the value of the precision datum; and emit by the connected object the geolocation information item and of the precision datum. ### Claim 9 A geolocation system, comprising: a plurality of located terminals; and at least one connected object comprising: a wireless receiver, which is configured to receive signals originating from the plurality of located terminals, said signals comprising location data for locating said located terminals; and a processor configured to: calculate a geolocation information item in respect of a position of the connected object on the basis of a plurality of the location data originating from different ones of the plurality of located terminals, determine a precision datum associated with the calculated geolocation information item, a value of this precision datum taking into account a number of occurrences of location data used for the calculation of the geolocation information item, and periodically activate and deactivate the wireless receiver and the calculation of the geolocation item, wherein a frequency of activating the wireless receiver evolves in a manner inversely proportional to the value of the precision datum; and an emitter, which is configured to emit the precision datum and the geolocation information item.
