Resumen
Resumen. La práctica dirigida consistió en plantear diferentes propuestas de diseños geométricos de redes geodésicas con diferentes coberturas a nivel nacional, comprobar la funcionalidad actual de NTRIP y de la Estación de Referencias Virtual (VRS) de Acueductos y Alcantarillados (AYA) dentro y fuera del Gran Área Metropolitana (GAM) y aplicar el método de ajuste simulado como estrategia de preanálisis de la factibilidad de las configuraciones de las redes planteadas. El objetivo fue definir una propuesta técnica de red geodésica para incrementar la cobertura y la operatividad de la metodología VRS. En el desarrollo del proyecto se realizaron levantamientos GNSS con equipo Spectra Precision SP85, para la aplicación de las metodologías VRS y NTRIP, se utilizaron visores cartográficos institucionales para la búsqueda de posibles sitios de monumentación de las antenas GNSS, las herramientas ArcGis Pro y QGIS para la elaboración de los mapas de cobertura y el software de Ajuste de Redes Geodésicas (ARGE) para la simulación de los diseños geométricos de red. Los resultados obtenidos comprueban que en las regiones fuera de la GAM como Limón y Puntarenas la cobertura de la red administrada por AYA es prácticamente nula y que existen sectores dentro de la región central con intermitencia de señal como Irazú y San Ramón. Por otra parte, en el análisis de las simulaciones de las configuraciones de redes propuestas y el diseño actual de la red activa de AYA, se obtuvieron valores máximos de 2,14 cm en el Norte y Este de la propuesta 3 y 5,5 mm en el Este de la red activa de AYA y valores mínimos de 1,37 cm en el Norte de la propuesta 2 y 1,7 mm en el Norte de la red actual de AYA. No obstante, la diferencia significativa está en el rango de cobertura de cada uno de los diseños geométricos. Finalmente, el proyecto concluyó con la elección de una propuesta técnica de red geodésica que abarca un 45% del territorio nacional aproximadamente, esta cumple con los rangos de tolerancias permitidas en la Norma Técnica de Información Geográfica de Costa Rica; además, el diseño geométrico está conformado por 6 antenas GNSS de AYA y la antena AACR de la red SIRGAS-CON.
Abstract. The guided practice consisted of proposing different geometric designs for geodetic networks with different coverage levels nationwide, checking the current functionality of NTRIP and the Virtual Reference Station (VRS) of Acueductos y Alcantarillados (AYA) inside and outside the Greater Metropolitan Area (GAM), and applying the simulated adjustment method as a pre-analysis strategy for the feasibility of the proposed network configurations. The objective was to define a technical proposal for a geodetic network to increase the coverage and operability of the VRS methodology. During the project, GNSS surveys were carried out using Spectra Precision SP85 equipment. For the application of VRS and NTRIP methodologies, institutional cartographic viewers were used to search for possible sites for GNSS antenna monuments, ArcGIS Pro and QGIS tools were used to create coverage maps, and Geodetic Network Adjustment (ARGE) software was used to simulate the geometric network designs. The results obtained confirm that in regions outside the GAM, such as Limón and Puntarenas, coverage of the network administered by AYA is practically nil and that there are areas within the central region with intermittent signal, such as Irazú and San Ramón. Furthermore, in the analysis of the simulations of the proposed network configurations and the current design of the active AYA network, maximum values of 2.14 cm were obtained in the north and east of proposals 3 and 5.5 mm in the east of AYA's active network, and minimum values of 1.37 cm in the north of proposal 2 and 1.7 mm in the north of AYA's current network. However, the significant difference lies in the coverage range of each of the geometric designs. Finally, the project concluded with the selection of a technical proposal for a geodetic network covering approximately 45% of the national territory. This proposal complies with the tolerance ranges permitted in Costa Rica's Technical Standard for Geographic Information. In addition, the geometric design consists of six AYA GNSS antennas and the AACR antenna from the SIRGAS-CON network.
