摘要
The invention discloses an antenna assembly configured to transmit terrestrial positioning signals from a relay platform having a frame of reference (x, y, z), said transmit being in at least a first mode with a radiating pattern having at least a main lobe having a narrow aperture in a (x, z) plane and a wide aperture in a (y, z) plane. It also discloses a relay platform comprising a receiver of a synchronization signal, a transmitter of positioning signals to an area of service comprising a number of rovers, and an antenna assembly configured to produce a radiating pattern adapted to transmit the positioning signals as a function of the environment of the relay platform and the rovers. In a number of embodiments the relay platforms may be organized in a network of platforms, possibly of masters and slaves, that receive feed-back from the rovers in the AoS so as to optimize the configuration of the antenna elements dynamically to optimize the QoS of positioning based on a number of selected quality indexes.
