13. A TECNOLOGIA MÓVEL, INTEGRADA A RECEPTORES GPS BLUETOOTH, APLICADA À GESTÃO TRIBUTÁRIA URBANA: CADASTRO DO IPTU E ISSQN / THE MOBILE TECHNOLOGY INTEGRATED BLUETOOTH GPS RECEIVER, APPLIED TO THE MANAGEMENT OF URBAN TAX: REGISTER OF IPTU AND ISSQN
The process of tax decentralization and the growing participation of municipal governments in the set of tax resources of Brazil, amplify its expansion in the management of public services dedicated to the population, creating conflicts in the structure of this level of government. The expansion and the improvement of the public services dedicated to the pop

14. O teorema da função implicita em um contexto aplicado e algumas conexões no calculo de areas de regiões planas / The implicit function thorem in an applied context and some connections in the calculus of the area of plane regions
The objective of this work is twofold. First, it presents an applied context for using the Implicit Function Theorem. This result allows to analyze the influence of the accuracy of the clocks involved in the working of the GPS (Global Positioning System), the receiver of which is a device used to locate the position of a point on the surface of the earth.

15. Morfologia e dinâmica das irregularidades ionosféricas de pequena escala e imageamento ionosférico por GPS / Morphology and dynamic of small-scale ionospheric irregularities and ionospheric imaging by GPS
The signals received from the Global Positioning System (GPS) satellites were used to study the behavior of three important geophysical parameters of the ionosphere: small-scale irregularities, their zonal drift velocities and the Total Electron Content (TEC). From the fluctuations (scintillations) in the amplitude of the GPS L1 signal (1575.42 MHz), detecte

16. Real time orbit determination using GPS navigation solution
This work analyses a real time orbit estimator using the raw navigation solution provided by GPS receivers. The estimation algorithm considers a Kalman filter with a rather simple orbit dynamic model and random walk modeling of the receiver clock bias and drift. Using the Topex/Poseidon satellite as test bed, characteristics of model truncation, sampling rat

17. The integration of GPS, vegetation mapping and GIS in ecological and behavioural studies
Global Positioning System (GPS) satellite navigation receivers are increasingly being used in ecological and behavioural studies to track the movements of animals in relation to the environments in which they live and forage. Concurrent recording of the animal's foraging behaviour (e.g. from jaw movement recording) allows foraging locations to be determined.

18. COMPARAÇÃO DE DOIS TIPOS DE SOLUÇÃO NO POSICIONAMENTO COM RECEPTORES GPS / COMPARISON BETWEEN TWO TYPES OF SOLUTION IN THE POSITIONING WITH GPS RECEIVERS
The basic principle of GPS use consists in the simultaneous measure of the distances between the receiver antenna and at least four satellites of the constellation. Known the distance from the satellite to the receiver antenna and the satellites coordinates, it is possible to calculate the user antenna coordinates in the same reference system of the satellit

19. Análise da precisão e acurácia de pontos georreferenciados com a técnica do código suavizado pela fase da portadora utilizando GPS de simples freqüência / Precision and accuracy analysis of georeferencing points using the carrier-smoothed-code technique with GPS single frequency receiver (L1)
The present dissertation has as objective to evaluate precision and discrepancies of coordinates (accuracy) obtained through GPS observations, in a rapid static method, measured by single frequency, which applies carrier-smoothed-code for different baseline length (20, 50, 75, 100, 150, 200 and 300 km), since continuous monitoring station from EESC/USP.

20. TERRAIN ELEVATION MODELLING WITH CONVENTIONAL ALTIMETRY AND GPS / MODELAGEM DA ELEVAÇÃO DO TERRENO COM ALTIMETRIA CONVENCIONAL E GPS
The Global Positioning System has all heights referred to the ellipsoid. However, for engineering applications it is necessary to have heights related to the earth gravitational field, which have physical meaning. In order to determine the orthometric height from the geoidal height, which is given at the GPS, it is necessary to know the geoidal undulation. T

21. Utilização do módulo "creatalink" para a transmissão, em tempo real, de sinais de correção para sistemas GPS diferenciais (DGPS) / Use of creatalink module to transmit in real time corrections signals for differential GPS (DGPS) systems
GPS is a radio navigation system base on a satellite network providing 24 hours radio data to determine point coordinates and world wide coverage. The precision is in the decametric range which is not adequate to many applications. DGPS or Differential GPS is a technique used to improve this precision down to metric level adding informa-tion to the receiver.

22. Orbit determination of artificial satellites in real time using gps navigation solution / Determinação de órbitas de satélites artificiais em tempo real através da solução de navegação de GPS
The Global Positioning System (GPS) is a satellite navigation system that allows the users to determine 3D positioning and the time with high precision. Its main purposes are: aid to radionavigation in three dimensions with high precision positioning, navigation in real time, global coverage and quick acquisition of data sent by the GPS satellites. It is pro
