Análise de séries temporais de multicaminho em estações de monitoramento contínuo

Data from reference stations are widely used in GNSS (Global Navigation Satellite System) positioning, and can be used in relative positioning or network-based positioning concept. Positioning accuracy will be directly influenced by errors in signals collected in these stations. In this paper, it is aimed at evaluating these data quality using temporal series of multipath index MP1 and MP2. A statistical study of temporal series with 7 years of daily observations related to 7 stations from RBMC (Rede Brasileira de Monitoramento Contínuo) was accomplished. In order to investigate trends and seasonality a linear regression model, correlograms, and Fourier periodograms were used. We also used a harmonic adjust to identify peaks on temporal series. At last, the possible causes of seasonality found in some stations were discussed. It was also possible to identify peaks in MP values of March and October months (mainly in stations located near geomagnetic equator).

Transformação de coordenadas com modelagem de distorções entre SAD69 e SIRGAS2000 com o uso de Thin-Plate Splines

Several countries have been passed by change processes in their fundamental geodesic structure with the focus on the adoption of geocentric reference systems. In Brazil, the adoption of the SIRGAS2000 evolves the coexistence of two realizations from the COrrego Alegre system, two realizations from the SAD69 system and one realization from the SIRGAS2000 system. To make use of products in the old reference systems, methods of coordinate transformation between the existent reference frames are necessary. So, in this paper one solution for the transformation between coordinates from different reference frames, based on Thin-Plate Splines (TPS), that allows the estimation of parameters from one linear transformation and also one non-linear model is presented. The TPS model was developed to work with tridimensional coordinates and in this paper the results and analysis are performed with simulated data and also with data from the official Brazilian Geodetic System (SGB). In the check points from SAD69 stations (realization of 1996 - SAD69/96), the values of RMSE obtained were of 78,2 mm in latitude and 67,5 mm in longitude, before the transformation to the SIRGAS2000. In the comparison between the TPS model and ProGriD (Brazilian software provided by IBGE), the statistical indicators were reduced in 97%, by using the TPS model. Based in the obtained results from real dataset, the TPS model appears to be promising, since it allows improving the quality of transformation process with simultaneous distortion modeling.

O risco ambiental representado por campos eletromagnéticos em Presidente Prudente (SP)

Currently the mobile services represent an essential tool in daily life of the population. However, while offering greater convenience to its users, there is growing concern about the harmful effects to human health, derived from daily exposure of the public to electromagnetic fields from radio base stations (RBS), since even today, there is no study proving that longterm exposure to low-level fields are not harmful to health. In Presidente Prudente has not been a study reporting values of measurements of electromagnetic fields from base stations installed in the city. Based on these data, this study aimed to assess the levels of electromagnetic exposure in the city of Presidente Prudente regarding recommended by international bodies, as well as propose measures that can reduce public exposure to electromagnetic fields. For measuring values of electromagnetic fields, we used appliance Electromagnetic Field Meter Portable Digital - DRE-050, the Instrutherm, following the methodology suggested and adapted from the Adilza Condessa Dode’study. In total, 49 points were mapped corresponding to the areas at risk of exposure to electromagnetic fields generated by the substations of power grid, transmission towers and telecommunication towers located in the city of Presidente Prudente (SP)
