  • Method and system for providing assistance to geolocation of node devices of an asynchronous RF network
    Patent number: 11067697
    Abstract: Where each node device is assumed to know the time-of-day with an accuracy of only plus or minus 1 second, the geolocation of said node device is determined by an A-GNSS server by help of a time-stamp known with an accuracy better than or equal to 10 milliseconds and added by at least one transceiver of the asynchronous RF network. Indeed, the technical feature of said asynchronous RF network according to which the time-of-day at which data are sent from each node device is known in a deterministic manner allows the A-GNSS server to determine retrospectively this time-of-day in function and with the precision of the time-stamp added by said at least one transceiver to the data packet issued from said node device over the asynchronous RF network.
