Ambiguity-Free Method for Fast and Precise GNSS Differential Positioning

Baselga Moreno, Sergio (American Society of Civil Engineers, 2014-02)

Methods based on integer ambiguity determination, such as the least-squares ambiguity decorrelation adjustment (LAMBDA) method, are currently used for precise global navigation satellite system (GNSS) differential positioning. ...
Control de Velocidad basado en Lógica Borrosa para Entornos Urbanos Congestionados

Milanés, V.; Onieva, E.; Pérez, J.; de Pedro, T.; González, C. (Universitat Politècnica de València, 2009-10-08)

[ES] Los sistemas de control de crucero adaptativo permiten, adecuando la velocidad, realizar el seguimiento del vehículo precedente en autopistas mientras este vehículo no se detenga. Sin embargo, en áreas urbanas donde ...
GPS and GLONASS Static and Kinematic PPP results

Anquela Julián, Ana Belén; Martín Furones, Ángel Esteban; Berné Valero, José Luis; Padin Devesa, Jorge (American Society of Civil Engineers, 2013-02)

Precise point positioning (PPP) involves observations from a single global navigation satellite system (GNSS) receiver and benefits of satellite orbit and clock products obtained from the global infrastructure of permanent ...
Multi sensor fusion framework for indoor-outdoor localization of limited resource mobile robots

Marín, Leonardo; Vallés Miquel, Marina; Soriano Vigueras, Ángel; Valera Fernández, Ángel; Albertos Pérez, Pedro (MDPI, 2013-10)

This paper presents a sensor fusion framework that improves the localization of mobile robots with limited computational resources. It employs an event based Kalman Filter to combine the measurements of a global sensor ...
PPP technique analysis based on time convergence, repeatability, IGS products, different software processing and GPS+Glonass constellation: a case study

Martín Furones, Ángel Esteban; Anquela Julián, Ana Belén; Capilla, Raquel M.; Berné Valero, José Luis (American Society of Civil Engineers, 2011)

In recent years interest has increased for precise point positioning (PPP), which provides an alternative to precise relative processing because of its potential as a reliable absolute positioning technique. PPP technique ...
Sistema de Posicionamiento para Vehículos Autónomos

Milanés, V.; Naranjo, J. E.; González, C.; Alonso, J.; García, R.; de Pedro, T. (Universitat Politècnica de València, 2008-10-10)

[ES] Uno de los objetivos más importantes de los Sistemas Inteligentes de Transporte (ITS) es evitar la pérdida de precisión en el posicionamiento y guiado del vehículo, debido a la disminución en la calidad de la señal ...
Tangent-to-curve transition on two-lane rural roads based on continuous speed profiles

Pérez Zuriaga, Ana María; Camacho Torregrosa, Francisco Javier; García García, Alfredo (American Society of Civil Engineers, 2013-11-01)

[EN] In the road geometric design process, speed variation along the road segment is one of the most popular criteria to evaluate road consistency, hence the importance of estimating operating speed and its variations. ...
