Code:    TIC2001-2356-C02-01
Funder:    Spanish Government
Start date:    2001 December 28th
End date:    2004 December 27th

SPCOM Participants:    Pau Closas Gómez, Juan Fernández Rubio, Carles Fernandez Prades and Alejandro Ramirez Gonzalez
SPCOM Responsible:    Juan Fernández Rubio

Summary

The objective of this project is to investigate a suite of techniques for the improvement of GPS/GNSS satellite navigation systems in varying scenarii: open, rural, urban and indoor. Three avenues will be undertaken: single- and multiple-antenna GNSS digital signal processing, GNSS observables processing and GNSS integration with other systems.
