Se analiza los distintos dispositivos que irán a bordo de la aeronave para determinar cuáles deben ser conectados al sistema Data Link, la distancia a la que debe llegar el enlace de datos, las condiciones de terreno en las que se realizarán los vuelos, los parámetros que afectarán las comunicaciones y las pruebas de campo realizadas para la aeronave.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract: In this paper we perform the calculations of minimum requirements in relation with carrier frequency, loss propagation, gain antenna, sensitivity communication of equipment. These parameters allow to configure a system of DataLink to be implemented in an air unmanned system (UAS). The equipment is analized to develop the project and to determine which of these should be connected to Data Link system. Also is discussed the distance of coverage, the field conditions in which the operation is carried out, parameters affecting communications and flight tests.]]></p></abstract>
