| Summary: | Low-cost antennas and receivers were evaluated in embedded systems altogether with a geodetic single-frequency receiver for measure a geodetic baseline; employing this equipment with a continuous reference station of the Red Geodésica Nacional Activa; located in Culiacan, Sinaloa, Mexico. The aim of this study was determinate the precision of the low-cost receivers employed, evaluating coordinates and distances obtained by applying the differential GPS method with academic and commercial software. Was found millimeter variances between the positioning of a geodetic receiver and the low-cost receivers for a geodetic baseline of 5.1 kilometers, doing possibly the implementation in geodetic or topographic applications. Se evalúa una línea base geodésica mediante la implementación de antenas y receptores de bajo costo en sistemas embebidos, así como un receptor geodésico de una frecuencia. Estas mediciones fueron ligadas a una estación de referencia continua de la Red Geodésica Nacional Activa, ubicada en Culiacán, Sinaloa, con el objetivo de determinar la precisión de los equipos de bajo costo estudiados. Para ello se analizan las coordenadas y distancias obtenidas al aplicar el método de posicionamiento diferencial con software académico y comercial. Los resultados presentan diferencias de orden milimétrico entre el posicionamiento con un receptor geodésico y uno de bajo costo para una línea base de 5.1 km que hacen posible la utilización de equipos de bajo costo en trabajos geodésicos y topográficos. |
