TWO CONTROL POINT METHOD [1 record]

Record 1 2002-12-13

English

Subject field(s)
  • Radio Waves
DEF

In ionospheric propagation over distances sufficiently long that one-hop transmission is precluded by the curvature of the Earth; an empirical method of estimating the maximum usable frequency for transmission between two points by way of a specified ionospheric layer from a knowledge of the properties of the ionosphere at the two control points.

Key term(s)
  • two control point method

French

Domaine(s)
  • Ondes radioélectriques
DEF

Méthode empirique d'estimation de la fréquence maximale utilisable, dans la transmission entre deux points au moyen d'une couche ionosphérique donnée basée sur les propriétés de l'ionosphère en deux points directeurs; cette méthode est appliquée dans la propagation ionosphérique sur des distances suffisamment grandes pour que la courbure de la Terre exclue la transmission par un seul saut.

Spanish

Campo(s) temático(s)
  • Ondas radioeléctricas
DEF

Método empírico de estimación de la frecuencia máxima útil, en la transmisión entre dos puntos por medio de una capa ionosférica determinada, basada en las propiedades de la ionosfera en dos puntos de control.

OBS

En propagación ionosférica sobre distancias lo suficientemente largas para que la transmisión de un solo salto no pueda ser posible por la curvatura de tierra.
