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 ...
Generating VRS data using atmospheric models: How far can we go?
(2007-12-01)
Nowadays, with the expansion of the reference stations networks, several positioning techniques have been developed and/or improved. Among them, the VRS (Virtual Reference Station) concept has been very used. In this paper ...

Simultaneous localization and mapping using an RGB-D camera for autonomous mobile robot navigation
(2021-08)
This paper presents the implementation of a simultaneous localization and mapping (SLAM) algorithm for autonomous mobile robot navigation. The proposed implementation uses an RGB-D camera to detect the environment and map ...
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, ...
