CA 2429086

A mobile unit, which communicates with a new and advantageous base station. The mobile unit includes a system for generation of position information and a transceiver for transmitting the position information. In the preferred embodiment, the transceiver is a CDMA system and the system for generating position information includes an arrangement for receiving a GPS signal. In the preferred embodiment, a GPS assisted arrangement is employed which is adapted to receive a signal from an airborne platform as well as from a satellite based platform. The base station is adapted to receive position information from a remote unit and provide a received position signal in response thereto. The base station is further equipped with a mechanism for directing a beam in response to the received position signal. In the illustrative embodiment, the mechanism for directing the beam is a smart antenna system including an antenna array and a beamforming network for driving the array to output the directed beam.

L'invention concerne une nouvelle unité mobile, en communication avec une nouvelle station de base améliorée. L'unité mobile comprend un système de génération d'informations de position et un émetteur-récepteur destiné à transmettre les informations de position. Dans un mode de réalisation préféré, l'émetteur-récepteur est un système AMCR et le système de génération d'informations de position comprend un dispositif de réception d'un signal GPS. Dans le mode de réalisation préféré, un dispositif GPS est utilisé, ce dispositif étant adapté pour recevoir un signal d'une plate-forme aérienne ainsi que d'un plate-forme satellite. La station de base de l'invention est adaptée pour recevoir des informations de position d'une unité à distance, et pour émettre un signal de position reçu en réponse. La nouvelle station de base est également équipée d'un mécanisme destiné à diriger un faisceau en réponse au signal de position reçu. Dans le mode de réalisation illustré, le mécanisme servant à diriger le faisceau est un système à antenne intelligente comprenant un réseau d'antenne et un réseau de formation de faisceau servant à commander le réseau d'antenne pour la génération du faisceau dirigé.
