ABSTRACT:
A satellite system antenna/high frequency unit of a mobile terminal of the present invention is constructed with a satellite system antenna for a mobile satellite communication system and a satellite system high frequency circuit and a first interface is provided externally of a casing of the unit. A ground system antenna/high frequency unit is constructed with a ground system antenna for a mobile ground communication system and a ground system high frequency circuit and a second interface is provided externally of a casing of the unit. A radio control unit includes a circuit portion within a casing thereof for demodulating a receiving signal to an input intermediate frequency signal and modulating a transmission signal and converting it into an intermediate frequency signal. The radio control unit further includes a radio control interface and a set of switches provided externally of the casing and, in use, only one of the first and second interfaces is connected to the radio control interface. The present mobile equipment can be used in an area which is not covered by a satellite by using a relay device for converting the mobile satellite system into the mobile ground system.
