June 12, 2008 REGIONAL PPP

© GMV, 2013 Precise Positioning Workshop 2013June 2013Page 10 REGIONAL PPP Global network not always affordable-> Demonstrator server allows to easily set up a regional network. Real time PPP comparison –Global products –Regional products Slight degradation performances

June 12, 2008 GALILEO PPP

© GMV, 2013 Precise Positioning Workshop 2013June 2013 GALILEO PPP (1) 4 operational Galileo satellites (E11, E12, E19 and E20) since late Large number of contributors to MGEX project ( providing RINEX 3.0X and RTCM observations. IOVs disposition provides up to 3 hours of common view over Europe -> feasibility for PPP solutions. Page 12

© GMV, 2013 Precise Positioning Workshop 2013June 2013 GALILEO PPP (2) TRIMBLE R10 receiver at GMVs premises. May 31 st. 150 minute window with 4 IOV satellites over Tres Cantos. Postprocessing of the recorded RINEX data. –Static PPP based on IGS products for precise coordinate determination. –Galileo only static PPP based on GPS+Galileo products. Position error below 5 cm. Page 13

June 12, 2008 PPP PROTECTION LEVELS

© GMV, 2013 Precise Positioning Workshop 2013June 2013 PPP PROTECTION LEVELS Based on process indicators and experimentation we generate a PL. Conservative approach for the definition of the PLs. Computed PLs bound the position error in nominal condition and under challenging environments. Intensive experimentation is foreseen. Page 15

June 12, 2008 CONCLUSIONS

© GMV, 2013 Precise Positioning Workshop 2013June 2013 CONCLUSIONS Full end user demonstration capability –Focused on robustness and operability –Enables to analyse different performance drivers –Extensive real-time field tests –Promising solutions for some of the main challenges Regional PPP: Feasible, promising results in real-time Galileo: Still proof of concept, but upcoming reality PL: Potential enabler for PPP applications Page 17
