“…Similarly, all observations were decimated to 15 s with TEQC software for static relative method, therefore Topcon Tools (Topcon, 2009) software was used for processing observations. Code and Phase observables were used with an elevation cut off angle of 15° (10 to 15° is commonly used as less elevation in the atmospheric effect degrade the received signal, since the visibility of the satellite is lower) (Hofmann-Wellenhof et al, 2007;Zamora-Maciel et al, 2020), precise ephemeris (SP3) from IGS (Spofford & Remondi, 1994), and IGS ANTEX file for Receiver antenna phase center correction. The obtained coordinates were analyzed using the official reference frame in Mexico (ITRF08…”

“…Wielgocka et al (2021) presented the feasibility of using low-cost dual-frequency GNSS receivers for land surveying, they also used a wellknown ZED-F9P receiver in conjunction with ANN-MB-00-00 antenna where the obtained results reached cm of precision in PPP with a 2.4 h of the session, regarding the vertical component the results still are inaccurate. As per the Static relative method in short and long distances, Romero-Andrade et al (2020) and Zamora-Maciel et al (2020), evaluate a geodetic baseline at ~5 and ~33 km from the CORS reference station, achieving a mm precision in consideration of survey time. present the reliability of the RTKLib (Takasu, 2013) software used in different embedded systems, also they found that the Precise Point Positioning could be considered for use in different embedded systems and achieve high precision.…”

The advancement of low-cost GNSS receivers with modern built-up characteristics has opened a new window to investigate the performance of various low-cost receivers with an outlook on their performance and suitability for varied geodetic purposes. The main objective of this study is to evaluate the positioning performance of single and double-frequency GNSS receivers in combination with geodetic antennas in static relative mode regarding Mexican regulations. The recorded observations were processed by a static relative method including the CORS station from the National Institute of Statistics and Geography in Mexico (INEGI). The results of the survey conducted at a distance of 4 and 33 km from CORS station show similar accuracy for all low-cost receivers. For low-cost GNSS receivers NEO-M8T, NEO-6T, and ZED-F9P the solutions that were obtained reached mm in horizontal precision using a geodetic grade antenna. Similarly, the ZED-F9P model was proved at a long distance from the CORS station and presents high precision. Regarding the vertical component, in all cases where the GGM10 model was included, the vertical component is not allowed to use for topography or geodetic works, however, the horizontal component where mm precision was achieved is allowed for different highly precision survey works.

“…Durante la época de los años 90, surgen los denominados equipos GNSS de bajo costo inicialmente para trabajos de mapeo (Tsakiri et al, 2018;Zamora-Maciel et al, 2020;Tsakiri et al, 2017), más sensibles en la recepción de señal logrando una potencia promedio de la señal recibida de -160 dB (Zhang and Schwieger, 2016) incluso con una sola frecuencia, en comparación a los equipos de orden geodésico que logran ~-128.5 dB (Zamora-Maciel et al, 2020).…”

Con el avance de la Geodesia y la mejora de las especificaciones técnicas de los receptores de bajo costo, los GNSS abren nuevas alternativas para investigar las capacidades técnicas y rendimiento real que proveen este tipo de receptores para diferentes propósitos geodésicos. En este contexto, la precisión alcanzable fue analizada usando el receptor de bajo costo GNSS ZED-F9P en conjunto con dos antenas de orden geodésico (ASH701975.01B y LEIAS10 NONE) y una antena de bajo costo (BEIBT300 NONE). Las observaciones GNSS fueron llevadas a cabo en un periodo de dos días para cada modelo de antena. El análisis fue realizado en tiempos de observación de 12, 6 y 1 h, respectivamente. Estas observaciones fueron procesadas usando el método relativo estático mediante la inclusión de una estación de referencia continua del Instituto Nacional de Estadística y Geografía, la cual está localizada a una distancia aproximada de 4 km. Los resultados demuestran que la mayor precisión es lograda en un periodo de 12 h, con diferencias mínimas de 3 cm para la componente Norte y 33 cm para la vertical. En este sentido, la solución menos precisa es obtenida en el periodo de 1 h resultando diferencias de 70 cm, 46 cm y 2.3 m para la componente Norte, Este y vertical respectivamente. With advancements in geodesy and enhancements in the technical specifications of low-cost receivers, GNSS opens up new avenues for investigating the capabilities and performance provided by these receivers for various geodetic purposes. In this context, the precision achievable using the low-cost GNSS receiver ZED-F9P in conjunction with two geodetic antennas (ASH701975.01B and LEIAS10 NONE) and a low-cost antenna (BEIBT300 NONE) was analyzed. GNSS observations were conducted over a 2-day period for each antenna model. The analysis involved observation durations of 12, 6, and 1 h. These observations were processed using the static relative method alongside a continuously operating GNSS station from the Active National Geodetic Network of the National Institute of Statistics and Geography, situated at ~4 km. The results demonstrate that the highest precision was achieved over a 12 h period, with minimal differences of 3 cm for the North component and 33 cm for the vertical component. Conversely, the least accurate solution was obtained within a 1 h observation period, resulting in differences of up to 70 cm, 46 cm, and 2.3 m for the North, East, and vertical components, respectively.
