The present invention seeks to provide a dual mode mobile satellite communication unit, which requires low communication cost and very little battery power, does not require always carrying a large unit frame and does not always provide great weight burden on the user. A terrestrial communication portable unit (B) is detachably mounted in the mobile satellite communication unit (A). The mobile satellite communication unit (A) as base unit does not include a key operating section, a display section and a speech transducer section having a microphone and a loudspeaker, and utilizes those mechanically assembled on the portable unit (B) side for keying and other operations. In an interlocked relation to the removal of the portable unit, the stand-by state of the base unit is turned off. It is thus possible to avoid wasteful battery power consumption on the base unit side.

La présente invention concerne une unité mobile et bimodale de communication par satellite, dont le coût de communication est faible, qui nécessite peu d'énergie batterie, ne nécessite pas toujours le port d'un châssis d'unité encombrant et ne constitue pas toujours une charge pesante pour l'utilisateur. Une unité portative de communications terrestres (B) est montée amovible dans ladite unité mobile de communication par satellite (A), laquelle en tant qu'unité de base ne comprend ni section de fonctionnement à touches, ni section d'affichage, ni section à transducteur de la parole comportant un microphone et un haut-parleur, mais implique l'utilisation de ces éléments assemblés mécaniquement sur le côté de l'unité portative, aux fins de numérotation ou d'autres opérations. Lorsque l'unité portative est dans une position de verrouillage par rapport à l'unité de base, l'état de veille de l'unité de base est coupé, et on évite ainsi un gaspillage de consommation d'énergie batterie du côté de l'unité de base.
