Abstract

Dispositivos, métodos y sistemas para la sincronización de enlace ascendente en red de satélite de acceso múltiple por división de tiempo (TDMA); en una realización, una terminal de satélite terrestre está configurada para comunicarse con un centro satelital a través de un satélite utilizando el protocolo de comunicación TDMA; la terminal de satélite terrestre está configurada para determinar su propia ubicación, una ubicación del satélite, estimar una distancia entre la ubicación de la terminal y la ubicación del satélite, determinar un avance temporal aproximado en base a la distancia estimada, y transmitir datos al satélite en base a avance temporal aproximado y el protocolo de comunicación TDMA; el avance temporal aproximado puede permitir la comunicación TDMA de enlace ascendente sin una transmisión de preámbulo en un canal de acceso aleatorio; la transmisión de preámbulo es requerida en muchos sistemas convencionales.
