Receiving apparatus for receiving satellite broadcasting electric wave to be mounted mobile vehicle being realized at low cost and not influence by the weather etc. The apparatus is provided with an antenna of which directivity pattern can be varied, and by a geomagnetism sensor mechanically coupled with said antenna to detect present orientation of the antenna, and comprising antenna controlling means by which the directivity pattern of the antenna is directed towards objective broadcasting satellite based on said detected orientation output. When an electric wave from a gap-filler station is to be received, the antenna is controlled to become non-directivity pattern automatically. For the antenna, a microstrip patch antenna having a plurality of conductive patches arranged in a plane is used.
Receiving apparatus for receiving satellite broadcasting electric wave at least comprising an antenna able to have a plurality of different directivities of the antenna, a tuner being fed with receiving signal of the antenna, a processor for controlling the antenna and for producing an antenna control signal for deciding one directivity pattern among the plurality of directivity patterns and a geomagnetism sensor,
Receiving apparatus for receiving electric wave sent from a ground transmitter station and from a broadcasting satellite, comprising an antenna for receiving at least the electric wave from the ground transmitter station and from the broadcasting satellite, means for detecting present orientation of said antenna, directivity control means for said antenna based on an output signal of said orientation detecting means, and signal receiving means for signal delivered from the antenna,
Receiving apparatus as claimed in any of the preceding claims, wherein the geomagnetism sensor is mounted on a horizontal position stabilizing device.
Receiving apparatus as claimed in any of the preceding claims, wherein an area code input device is provided to adjust locational error of geomagnetism in a very wide area.
