A method of acquisition by navigation terminals (T1; Tn), of navigation signals broadcast by satellites of a GNSS global navigation system, said method comprising: • A communication of information through a communication channel of a radio frequency link type between a plurality of terminals (T1; Tn) close to one another, having time and frequency synchronization, those terminals thereby forming a synchronized network • And, for each satellite in view, a collaboration between terminals (T1; Tn) of the network thereby formed in order to determine so-called syntonization parameters of the navigation signal relative to the shared time and frequency reference, the said collaboration comprising: - management of the sharing of their respective resources so that each one contributes to the calculations involved in determining the synchronization parameters of the navigation signal; - said management of the sharing of resources comprising the allocation of one or more exploration tasks (P1; Pn) based on the resources of each terminal; - said allocation of exploration tasks (P1; Pn) comprising a sharing of the global time and frequency search space; - said sharing of the global time and frequency search space comprising overlapping ranges; - said sharing of the frequency search space comprising the division into subsets of a frequency range in which the navigation signal of a satellite in view is likely to be received; - said sharing of the time search space comprising the division into subsets of a time range in which the phase of the spreading code used to modulate the carrier emitted by a satellite in view is likely to be found, relative to a time reference; - the transmission by the communication channel of the results obtained for obtaining syntonization parameters of the navigation signal in order for the terminals (T1; Tn) of the network to syntonize to the signal of the satellite in view. • A communication of information through a communication channel of a radio frequency link type between a plurality of terminals (T1; Tn) close to one another, having time and frequency synchronization, those terminals thereby forming a synchronized network • And, for each satellite in view, a collaboration between terminals (T1; Tn) of the network thereby formed in order to determine so-called syntonization parameters of the navigation signal relative to the shared time and frequency reference, the said collaboration comprising: - management of the sharing of their respective resources so that each one contributes to the calculations involved in determining the synchronization parameters of the navigation signal; - said management of the sharing of resources comprising the allocation of one or more exploration tasks (P1; Pn) based on the resources of each terminal; - said allocation of exploration tasks (P1; Pn) comprising a sharing of the global time and frequency search space; - said sharing of the global time and frequency search space comprising overlapping ranges; - said sharing of the frequency search space comprising the division into subsets of a frequency range in which the navigation signal of a satellite in view is likely to be received; - said sharing of the time search space comprising the division into subsets of a time range in which the phase of the spreading code used to modulate the carrier emitted by a satellite in view is likely to be found, relative to a time reference; - the transmission by the communication channel of the results obtained for obtaining syntonization parameters of the navigation signal in order for the terminals (T1; Tn) of the network to syntonize to the signal of the satellite in view. - management of the sharing of their respective resources so that each one contributes to the calculations involved in determining the synchronization parameters of the navigation signal; - said management of the sharing of resources comprising the allocation of one or more exploration tasks (P1; Pn) based on the resources of each terminal; - said allocation of exploration tasks (P1; Pn) comprising a sharing of the global time and frequency search space; - said sharing of the global time and frequency search space comprising overlapping ranges; - said sharing of the frequency search space comprising the division into subsets of a frequency range in which the navigation signal of a satellite in view is likely to be received; - said sharing of the time search space comprising the division into subsets of a time range in which the phase of the spreading code used to modulate the carrier emitted by a satellite in view is likely to be found, relative to a time reference; - the transmission by the communication channel of the results obtained for obtaining syntonization parameters of the navigation signal in order for the terminals (T1; Tn) of the network to syntonize to the signal of the satellite in view.
