YellowScan tiene m\u00e1s de una forma de alcanzar la precisi\u00f3n centim\u00e9trica.<\/h2>\n

Las soluciones YellowScan LiDAR utilizan tarjetas INS asistidas por GNSS de Applanix que permiten m\u00faltiples m\u00e9todos de posprocesamiento para alcanzar una precisi\u00f3n centim\u00e9trica.<\/p>\n

Utilizando un receptor GNSS de doble frecuencia, como el que se emplea en los sistemas YellowScan LiDAR, puede localizarse con una precisi\u00f3n de un metro. Sin embargo, la mayor\u00eda de los trabajos topogr\u00e1ficos actuales requieren una precisi\u00f3n centim\u00e9trica o superior. \u00bfC\u00f3mo lo conseguimos? Para obtener este nivel de precisi\u00f3n, es necesario corregir el LiDAR y su trayectoria de vuelo. Para conseguirlo, una t\u00e9cnica com\u00fan es utilizar una fuente separada de observaciones GNSS, de ah\u00ed el t\u00edpico t\u00e9rmino \u00abdiferencial\u00bb aplicado a estos m\u00e9todos. Estas fuentes de correcciones diferenciales pueden proceder de la grabaci\u00f3n de un receptor \u00abf\u00edsico\u00bb, firmemente plantado en el planeta Tierra, a menudo denominado estaci\u00f3n base, o de una estaci\u00f3n de referencia \u00abvirtual\u00bb.<\/p>\n

Podemos definir los receptores f\u00edsicos como su propio receptor GNSS de doble frecuencia instalado sobre el terreno cerca de la zona de estudio, situado en un punto de referencia conocido o en una posici\u00f3n desconocida. Los \u00abpros\u00bb de este m\u00e9todo son que es tuyo, puedes tocarlo, lo controlas y decides d\u00f3nde instalarlo. Por otro lado, los \u00abcontras\u00bb son que es una pieza de hardware que tiene un coste y hay que mantener. Otro enfoque es un receptor GNSS que forme parte de una red nacional (CORS, EUREF, RGP…) situado a 20 km o menos del lugar de la encuesta. Los \u00abpros\u00bb aqu\u00ed son que es un servicio gratuito en un puesto certificado. Los \u00abcontras\u00bb son que es un servicio que puede interrumpirse, puede estar lejos del lugar de la encuesta, la cuadr\u00edcula es gruesa, la l\u00ednea de base es larga y no es tuyo.<\/p>\n

Si busca una referencia virtual, YellowScan integra la tecnolog\u00eda Trimble\/Applanix en sus soluciones, lo que le permite acceder a m\u00e9todos de postprocesamiento adicionales sin tener que poseer una estaci\u00f3n base. Esto incluye el servicio de suscripci\u00f3n RTX de Trimble, disponible en todo el mundo, que le permite procesar su trayectoria en tan solo unos clics. Los \u00abpros\u00bb son que es mundial, r\u00e1pido y no requiere hardware adicional. Los \u00abcontras\u00bb son que el servicio sigue teniendo un coste.<\/p>\n

A trav\u00e9s de la plataforma de YellowScan, puede utilizar Applanix Smartbase para crear una estaci\u00f3n de referencia virtual (VRS) en el centro de su \u00e1rea de estudio basada en sus redes GNSS nacionales. Los \u00abpros\u00bb son que no se necesita hardware adicional y los \u00abcontras\u00bb son que depende del pa\u00eds y que el coste del servicio es un factor a tener en cuenta.<\/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
