The auto-tracking mode uses the conical scanning principle. With a scanner situated in the antenna feed, the peak of pattern direction describes a cone in space around the geometric axis of the antenna. The signal received by the station is amplitude-modulated, the depth of this modulation increasing with the difference between the satellite direction and the direction of the geometric antenna axis. 1, record 1, English, - conical%20scanning

Le système de poursuite automatique fonctionne selon le principe bien connu de l'exploration conique. Grâce à un dispositif d’exploration spécial monté sur le système d’alimentation de l'antenne, la direction du rayonnement maximal décrit un cône, dans l'espace autour de l'axe géométrique de l'antenne. Le signal reçu par la station est modulé en amplitude, la profondeur de cette modulation augmentant avec l'écart entre la direction du satellite et la direction de l'axe géométrique de l'antenne. 1, record 1, French, - exploration%20conique

Great attention is now devoted to combined modulation methods and particularly to multiple-phase-and-amplitude-shift-keyed signal sets (MPASK, sometimes called APK of ASK-PSK), which may be interpreted by means of a two-dimensional phase-amplitude signal. 1, record 3, English, - multiple%2Dphase%2Dand%2Damplitude%2Dshift%2Dkeyed%20signal%20set

On porte actuellement un grand intérêt aux méthodes de modulation mixtes, en particulier celle qui fournit des signaux composites à manipulation par déplacement de phase et d’amplitude multiple(appelée MDPA-M et parfois MAP, contraction de MDA-MDP), dont on peut représenter le signal modulé en phase et en amplitude dans un espace à deux dimensions. 1, record 3, French, - signal%20composite%20%C3%A0%20manipulation%20par%20d%C3%A9placement%20de%20phase%20et%20d%26rsquo%3Bamplitude%20multiple
