United Nations office for outer space affairs GNSS web-pages
(2004-07-01)
In this article, Dr. J.F.G. Monico introduces the on-line resources at the website of the UN Office for Outer Space Affairs, including the web-based GPS resources and their technical background information. Its purpose is ...
A Model for the Relationship between Rainfall, GNSS-Derived Integrated Water Vapour, and CAPE in the Eastern Central Andes
(Multidisciplinary Digital Publishing Institute, 2021-09)
Atmospheric water vapour content is a key variable that controls the development of deep convective storms and rainfall extremes over the central Andes. Direct measurements of water vapour are challenging; however, recent ...
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 ...

Integration of satellite signal acquisition algorithm to the GNSS-SDR framework
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia de ComputaçãoEngenharia de Computação e Automação, 2022-07-27)
The Variance-Triggered Two-Step Acquisition (VTTS) is an algorithm that composes one
step of the position calculation of a Global Navigation Satellite System (GNSS) receiver.
The main function is to detect visible ...
Avaliação de multicaminhamento em diferentes coberturas vegetais - Global Navigation Satellite System (GNSS) x Estação Total.
(Universidade do Vale do Rio dos Sinos, 2017)

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 ...
