The invention relates to a method for determining the location of a detonator (101) in a wireless network of electronic detonators (10), the method comprising: a step of transmitting a signal by the detonator referred to as the transmitting detonator; a step of receiving the signal by at least one other detonator of the network referred to as the receiving detonator; and a step of calculating the distance between the transmitting detonator and the receiving detonator according to the power of the signal that has been received by the receiving detonator. The invention also relates to a method for programming a blast plan, the method comprising steps of a method for determining the location of a detonator. The invention also relates to a system (1) configured to implement a method for determining the location of a detonator. The invention also relates to the use of signal power loss to identify a location of a detonator (101).
