Abrégé
(EN) A method of generating scintillation prediction data comprises: • a) for a plurality of satellites (12A), and reference stations (10A, 10B, 10C, 10D) measuring phase scintillation data, satellite by satellite for each reference station during multiple epochs (t-2, t-1, t, t+k); • b) forecasting an expected phase scintillation value for each satellite and reference station for a period of at least 24 hours based on a cyclical prediction model; • c) for a given user location (20) and a given satellite, spatially interpolating the expected phase scintillation values of the plurality of reference stations to determine a predicted phase scintillation index; • d) repeating step c) for further satellites visible from the user location.
(FR) L'invention concerne un procédé de génération de données de prévision de scintillation qui comprend : • a) pour une pluralité de satellites (12A) et de stations de référence (10A, 10B, 10C, 10D), mesurer des données de scintillation de phase, satellite par satellite pour chaque station de référence pendant de multiples périodes (t-2, t-1, t, t+k) ; • b) prévoir une valeur de scintillation de phase attendue pour chaque satellite et station référence pendant une période d'au moins 24 heures sur la base d'un modèle de prédiction cyclique ; • c) pour un emplacement d'utilisateur donné (20) et un satellite donné, interpoler spatialement les valeurs de scintillation de phase attendues de la pluralité de stations de référence afin de déterminer un indice de scintillation de phase prévu ; • d) répéter l'étape c) pour les autres satellites visibles depuis l'emplacement d'utilisateur.
