Abstract (en)
The telephone is linked with a satellite location system. An automatic orientation device acts on an antenna (3) of the system. Negative or positive acceleration undergone by the system is measured. An antenna support moves through an angle of 180 degrees . The support orients itself based upon gravity so as to give maximum antenna gain. The antenna support moves within a sphere (7) and is held by two cylindrical coins (9). A stop (10) limits the movement of the support to 180 degrees and allows a lower cylinder to bypass a cable opening.
