The particular form of offset quaternary phase shift keyed modulation which is used in AMSS [aeronautical mobile-satellite service] for channel rates greater than 2 400 bits/s. A-QPSK is a modulation technique that maps a "0" into a 0 degrees and "1" into 180 degrees, or "0" into 90 degrees and "1" into 270 degrees, alternating between the two options on successive bits. 1, record 1, English, - aviation%2DQPSK

Forme particulière de modulation par déplacement de phase en quadrature décalée, utilisée dans le SMAS [service mobile aéronautique par satellite] pour des débits supérieurs à 2,4 kbit/s. Selon la technique de modulation A-QPSK, «0» correspond à 0 degré et «1» à 180 degrés, ou bien «0» correspond à 90 degrés et «1» à 270 degrés, et ces deux options alternent d'un bit au suivant. 1, record 1, French, - modulation%20par%20d%C3%A9placement%20de%20phase%20en%20quadrature%20%2D%20aviation

Forma particular de modulación por desplazamiento de fase en cuadratura que se utiliza en el SMAS [servicio móvil aeronáutico por "satélite"] para velocidades de transmisión por canal superiores a 2 400 bits/s. La A-QPSK es una técnica de modulación que transforma un "0" en 0 grados y un "1" en 180 grados, o un "0" en 90 grados y un "1" en 270 grados, alternando entre las dos opciones en bits consecutivos. 1, record 1, Spanish, - QPSK%20para%20la%20aviaci%C3%B3n
