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

GALILEO PPP (1)
4 operational Galileo satellites (E11, E12, E19 and E20) since late 2012.
Large number of contributors to MGEX project (http://igs.org/mgex/) providing RINEX 3.0X and RTCM observations.
IOVs disposition provides up to 3 hours of common view over Europe -> feasibility for PPP solutions.

GALILEO PPP (2)
TRIMBLE R10 receiver at GMVs premises.
May 31st. 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.

PPP PROTECTION LEVELS
![Page 15: AN INDUSTRY APPROACH TO PRECISE POINT POSITIONING GNSS PPP WORKSHOP D. Calle A. Mozo P. Navarro R. Píriz D. Rodríguez G. Tobías JUNE 13 TH, 2013 - GNSS.](https://reader035.fdocuments.us/reader035/viewer/2022062407/56649dc85503460f94abdd94/html5/thumbnails/15.jpg)

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.

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
