The present invention provides a multiple band mobile radio (also referred to as a Wireless Communication Device (WCD)) (102) capable of communicating with both a satellite communication system (108, 114) and a terrestrial communication system (120, 122). The satellite communication system can be a Low Earth Orbit (LEO) satellite communication system. The terrestrial communication system can be a Personal Communication System (PCS), or a cellular system, including either an analog or a digitally based cellular system. The WCD can concurrently receive signals from the terrestrial communication system and the satellite communication system. Also, the WCD (102, 300, 470, 500, 600) can receive signals useful for position location, such as a GPS satellite signal alone, or both GPS and satellite communication signals, simultaneously.

L'invention concerne une radio mobile à bande multiple (aussi connu sous le nom de dispositif de communication sans fil (WCD)) (102) permettant de communiquer à la fois avec un système de communication par satellite (108, 114) et un système de communication de terre (120, 122). Le système de communication par satellite peut consister en un système de communication par satellite à orbite basse (LEO). Le système de communication de terre peut consister en un système de communication personnel (SCP), ou un système cellulaire, comprenant soit un système cellulaire analogique, soit un système cellulaire numérique. Le WCD peut recevoir simultanément des signaux provenant du système de communication de terre et du système de communication par satellite. Il (102, 300, 470, 500, 600) peut recevoir des signaux utiles pour localiser une position, tels qu'un signal reçu par satellite GPS unique, ou des signaux GPS et de communication par satellite, simultanément.
