Galileo CZ – 5. GNSS software receiver

• Concept – software defined radio• Modular architecture – RF unit + DSP unit

+ HPC• Purpose – multiplatform modular receiver,

position sensor for other projects

Theme in relationship with topics beyond frame of the project


Galileo CZ

• FEE CTU Prague• 2001–2006• Wide area of research• Outputs of pilot projects should provide

background and knowledge for seamless implementation of Galileo (GNSS) in applications in CR

• http://radio.feld.cvut.cz/satnav/galileo_cz/



• DGPS Reference Station – still in service• Project Galileo CZ• Indoor/AGNSS – GNSS software receiver• Other projects


Indoor navigation/AGNSS

• Signal impulse response modeling• Indoor signal processing with aided

information from external antenna• Signal processing algorithms –

implementation into GNSS receiver

Assisted GNSS (AGNSS)

Present GNSS activities - Development and Production

Main trends of development and production:• GPS/GNSS receivers development and

production (DICOM Inc., Uherské Hradiště)

• Use of GNSS technology in positioning related applications – Systems for Localization of Stolen Vehicles

(AutoAWACS Bohemia, SECAR Bohemia – Sherlog)– Fleet Management Systems

(Princip - LUPUS,RADOM – RACARDT,...)


Present GNSS activities - Other Areas of application

• Geodesy, Cartography, Surveying• Ecology – localization and monitoring of

black dumps, trail paths, etc.• Integrated rescue system – Fire brigades

fire hose valves localization, localization and summarization of rescue spots for injured rock climbers, etc.

• Riverbed mapping


Agenda


– Research– Development & Production– Other activities

• Future


Future of GNSS in CR

• GNSS systems research• Coordination of research activities

related to GNSS in CR• Cooperation in EU area and abroad• Popularization of GNSS and its

applications in CR
