Inventions Utilizing Satellite Navigation Systems in the Railway Industry – An Analysis of Patenting Activity
(Universidad Alberto Hurtado. Facultad de Economía y Negocios, 2014)
Investigações preliminares sobre a influência do clima espacial no posicionamento relativo com GNSS
(Universidade Estadual Paulista (UNESP), 2014)
Using cubic splines to mitigate systematic errors in GPS relative positioning
(2004-12-01)
Systematic errors can have a significant effect on GPS observable. In medium and long baselines the major systematic error source are the ionosphere and troposphere refraction and the GPS satellites orbit errors. But, in ...
GNSS REFLECTOMETRY MEASUREMENT OF SNOW DEPTH AND SOIL MOISTURE IN THE FRENCH ALPS
(Ieee, 2015-01-01)
Over the last ten years Earth observing systems have grown considerably and thus allow the use of Global Navigation Satellite System (GNSS) signals for remote sensing. Several studies in the U.S. have proven the ability ...
GNSS reflectometry measurement of snow depth and soil moisture in the French Alps
(2015-11-10)
Over the last ten years Earth observing systems have grown considerably and thus allow the use of Global Navigation Satellite System (GNSS) signals for remote sensing. Several studies in the U.S. have proven the ability ...
GPS Diffractive Reflectometry: Footprint of a Coherent Radio Reflection Inferred From the Sensitivity Kernel of Multipath SNR
(Ieee-inst Electrical Electronics Engineers Inc, 2016-10-01)
The validation of remote sensing environmental estimates requires knowledge of their spatial extent and resolution. Here, we consider coherent radio reflections routinely observed in ground-based global positioning system ...
Mitigating systematic errors for single frequency GPS receivers employing a penalized least squares methodology
(2006-12-27)
Among the positioning systems that compose GNSS (Global Navigation Satellite System), GPS has the capability of providing low, medium and high precision positioning data. However, GPS observables may be subject to many ...
Grade ionosférica para aplicações em posicionamento e navegação com GNSS
(Universidade Estadual Paulista (UNESP), 2010-09-20)
O efeito da ionosfera é a maior fonte de erro sistemático nos sinais transmitidos pelos satélites do GNSS (Sistema Global de Navegação por Satélite), o qual afeta principalmente a acurácia do posicionamento e navegação ...
