| dc.description | La transferencia de tiempo y frecuencia mediante sistemas GNSS es fundamental para garantizar la sincronización y trazabilidad temporal en aplicaciones científicas, industriales y de telecomunicaciones. Sin embargo, los sistemas comerciales especializados pueden representar altos costos de adquisición e implementación. Este trabajo presenta el desarrollo de un prototipo de bajo costo para la comparación de señales de osciladores atómicos mediante la técnica satelital Common-View. El sistema integra un receptor GNSS, una referencia externa proveniente de un oscilador atómico de cesio y herramientas de software para la adquisición y procesamiento de datos. El prototipo permite capturar observaciones GNSS, convertirlas a formatos RINEX, aplicar correcciones temporales y generar archivos CGGTTS utilizados en comparaciones internacionales de tiempo. La validación se realizó frente a un sistema de referencia desarrollado por el NIST, conectando ambos sistemas a UTC(INM). Los resultados demuestran la viabilidad técnica de implementar sistemas de transferencia de tiempo mediante GNSS utilizando receptores de bajo costo, fortaleciendo las capacidades metrológicas y de investigación en tiempo y frecuencia. | |
| dc.description.abstract | Time and frequency transfer using GNSS is essential for ensuring synchronization and temporal traceability in scientific, industrial, and telecommunications applications. However, specialized commercial systems may involve high acquisition and implementation costs. This work presents the development of a low-cost prototype for comparing atomic oscillator signals using the satellite-based Common-View technique. The system integrates a GNSS receiver, an external reference provided by a cesium atomic oscillator, and software tools for data acquisition and processing. The prototype enables the acquisition of GNSS observations, their conversion into RINEX formats, the application of time corrections, and the generation of CGGTTS files used in international time comparisons. The prototype was validated against a reference system developed by NIST, with both systems connected to UTC(INM). The results demonstrate the technical feasibility of implementing GNSS time-transfer systems using low-cost receivers, strengthening metrological and research capabilities in time and frequency. | |
