    Martín Escalona, Israel; Barceló Arroyo, Francisco; De la fuente, Andres (2009)
    Conference report
    Restricted access - publisher's policy
    Hybridization is a hot topic in the location field. Since there is no universal location technique that is capable of positioning in indoor and outdoor environments, two or more techniques must be coupled to produce a ...
  • On the Resolution of position ambiguity when integrating GNSS and WLAN observables 

    Fernández, Daniel; Ciurana Adell, Marc; Jofre, Martí; Gutiérrez, Esteban; Chester, Ed; Barceló Arroyo, Francisco; Martín Escalona, Israel (2010)
    Conference report
    Restricted access - publisher's policy
    This contribution proposes a positioning system that fuses GPS pseudoranges and WLAN ranges when fewer than four GPS satellites are available. In order to enhance as much as possible the positioning availability, a tight ...
