Accuracy assessment of Precise Point Positioning with multi-constellation GNSS data under ionospheric scintillation effects
(2018-01-01)
GPS and GLONASS are currently the Global Navigation Satellite Systems (GNSS) with full operational capacity. The integration of GPS, GLONASS and future GNSS constellations can provide better accuracy and more reliability ...
Posicionamento por ponto de alta precisão utilizando o GPS: Uma solução para a geodinâmica
(2000-03-01)
Point positioning from GPS data can provide precision varying from 100 meters to a few millimeters at the level of 95% probability. To reach the best level of accuracy, users need proper equipment and software, as well as ...
The accuracy potential of Galileo E5/E1 pseudoranges for surveying and mapping
(2011-12-01)
In the paper we discuss the potential of the new Galileo signals for pseudorange based surveying and mapping in open areas under optimal reception conditions (open sky scenarios) and suboptimal ones (multipath created by ...
A simplified model for friction compensation in precise feed drives
(Inderscience Enterprises, 2018-11)
Friction is a complex phenomenon with negative effects on the precision of positioning systems. In this work, a single-state friction model for control purposes, aimed to simplify the implementation of control algorithms ...
Two-State GMS-Based Friction Model for Precise Control Applications
(Springer, 2016-05)
The capability of a model to represent the complex friction behavior is particularly important for systems where friction has a major impact on motion precision. In this work a GMS-based model is proposed which would require ...
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 ...
