La posici\u00f3n GPS de los drones LiDAR utiliza la relatividad general, una teor\u00eda de la gravitaci\u00f3n desarrollada por Albert Einstein entre 1907 y 1915.<\/h2>\n

Para entender esta frase, es importante recordar c\u00f3mo funciona un Sistema de Posicionamiento Global (GPS).<\/p>\n

Los sat\u00e9lites que orbitan alrededor de la Tierra transmiten informaci\u00f3n sobre su posici\u00f3n y la hora actual a intervalos regulares. El receptor GPS en la Tierra calcula su distancia a cada sat\u00e9lite calculando la diferencia horaria entre la hora de salida y la hora de llegada de la se\u00f1al. La distancia es igual al tiempo de viaje multiplicado por la velocidad de la luz. Un receptor GPS s\u00f3lo necesita recibir se\u00f1ales de un m\u00ednimo de tres sat\u00e9lites para ser localizado en el espacio por trilateraci\u00f3n (es decir, triangulaci\u00f3n + distancia).<\/p>\n

\u00bfQu\u00e9 tiene esto que ver con la relatividad?<\/strong><\/p>\n

Cada sat\u00e9lite tiene un reloj at\u00f3mico que le da la hora exacta. Sin embargo, Albert Einstein explica que el tiempo fluye m\u00e1s lentamente bajo el efecto de una fuerte atracci\u00f3n gravitatoria. El tiempo a bordo del sat\u00e9lite fluye m\u00e1s r\u00e1pido que en la Tierra (porque la atracci\u00f3n terrestre es m\u00e1s d\u00e9bil). El c\u00e1lculo de la distancia desde la hora de salida y la hora de llegada de la se\u00f1al emitida por el sat\u00e9lite debe tener en cuenta este efecto. Si no tuvi\u00e9ramos en cuenta este efecto, \u00a1la indicaci\u00f3n del GPS se desplazar\u00eda unos diez kil\u00f3metros al d\u00eda!<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
