Activities
Collect ESTB/EGNOS Data and Evaluate
them from different sites in Europe
 Group of experts to support:

the development of the tools need in the future
EGNOS Operational Validation
 definition of data collection procedures


Baseline for the future static campaign in the
GOV Plan – extended with the ANSP
participation
Activities (2)




Data collection at regular intervals - full flexibility
Regular performance reports - Web site
Recommendations for the tools - PEGASUS
Deep analysis on specific subjects/anomalies

VPL trend analysis

Protection Levels and MT 25 in PEGASUS

High fast corrections values, UDREI holes (14/02/03)

Ionospheric tests - ESTB corrections monitoring

ESTB Performance against losing satellites

MIs appearing due to bad ionospheric corrections

Multipath analysis…
Why BUTE?


Extension of network to the east
Broad GNSS experience:

GPS education since 1988/1995

Operating a permanent station since 2000


especially for surveyors

participating in the EUREF IP project

Concluding remarks

BUTE and Integricom involved in EGNOS
data collection and data analysis

Eurocontrol GOV activities
Building expertise on EGNOS within a
network of 6 European Universities and many
ASP-s
 Ready to take step to Galileo
