Abstract:
1. A tracking system configured to track a product and/or an activity, the tracking system comprising: a tracing device and a verification server, the tracing device being coupled with the verification server by means of communication means configured to allow exchange of data between the tracing device and the verification server; the tracing device being coupled with a first satellite localization receiver to acquire data therefrom; the first satellite localization receiver being configured to: receive signals from a satellite localization system; process the received signals to obtain satellite localization observables; and compute locations based on the satellite localization observables; the tracing device being configured to: acquire positioning data from the first satellite localization receiver, the positioning data comprising a location computed by the first satellite localization receiver, and a location time which represents time and data at which the location is computed by the first satellite localization receiver, the positioning data being related to the product and/or the activity to be tracked; select a satellite localization observable based on which the location is computed by the first satellite localization receiver; acquire from the first satellite localization receiver the selected satellite localization observable; and provide the verification server with the positioning data and the satellite localization observable acquired from the first satellite localization receiver; the verification server being configured to: perform a location consistency check based on the location comprised in the positioning data provided by the tracing device, and on the satellite localization observable provided by the tracing device; generate a validation code on the basis of an outcome of the location consistency check, and on the basis of the positioning data provided by the tracing device; and provide the tracing device with the generated validation code; the tracing device being further configured to: store the positioning data, and the validation code provided by the verification server on tracking means associated with the product and/or the activity to be tracked.
