(In: ENCONTRO DE JOVENS TALENTOS DA EMBRAPA CERRADOS, 3., 2007, Planaltina, DF. Resumos apresentados. Planaltina, DF: Embrapa Cerrados, 2007. p. 43., 2011)
Towards forecasting and mitigating ionospheric scintillation effects on GNSS
(2007-12-01)
The effect of the ionosphere on the signals of Global Navigation Satellite Systems (GNSS), such as the Global Positionig System (GPS) and the proposed European Galileo, is dependent on the ionospheric electron density, ...
Gps-Inspired Method For Rodent Tracking Using Arduino-Based Open Field And Fft Analysis
(2014)
Due to the fact that video-based tracking methods for laboratory rats are expensive and time consuming,
a novel approach of the time dependent position was developed. In this work we show a new kind of cage
for performing ...
Ionospheric Equatorial Plasma Bubble effects on L1 single frequency code GPS positioning using precise ephemerides
(2021-01-01)
Amplitude and phase variations of Global Navigation Satellite Systems (GNSS) radio signals used by the aeronautic community occur due to ionospheric irregularities (ionospheric scintillation), which may cause the degradation ...
Multipath reduction from GPS double differences using wavelets: How far can we go?
(2004-12-01)
Wavelets are being extensively used in Geodetic applications. In this paper, the Multi-Resolution Analysis (MRA) using wavelets is applied to pseudorange and carrier phase GPS double differences (DDs) in order to reduce ...
Modifying the stochastic model to mitigate GPS systematic errors in relative positioning
(2007-12-01)
The GPS observables are subject to several errors. Among them, the systematic ones have great impact, because they degrade the accuracy of the accomplished positioning. These errors are those related, mainly, to GPS ...
