摘要： An asset location, tracking, and recovery system and method includes a network of VHF towers and a control center receiving signals from and transmitting signals to the VHF towers. Primary locating units each include a transmitter, a receiver, and a transponder activated when a signal is transmitted by the control center via the VHF towers to the receiver. Auxiliary locating units include at least a transmitter emitting a signal received by at least one primary locating unit receiver which relays that signal to the control center via the VHF towers from the primary locating unit transmitter.
