Galileo Governance: ESA’s role
• Translate Mission requirements into System Implementation Requirements
• System Architect and Design Authority• Infrastructure procurement• System full deployment, integration and validation• Initial operations to support validation and “interim
service” provision during full deployment• Handover to EC for transfer to Operational Phase
EC and ESA roles:• EC Programme Manager• ESA System Prime / Procurement Agent

• mass 600 kg, power 700 W• Launched on 29th Dec 2005• Signal in Space broadcast
since 2th Jan 2006

GIOVE Satellites
GIOVE-A In Orbit Status
• Nominal mission completed in March 2008– 12-month mission extension to continue operations until
March 2009– all operations onboard the spacecraft remain nominal– SSTL expects the spacecraft to continue operating
beyond the current extension period– Latest in-orbit test campaign in August 2008 confirmed
that performance of navigation signals remains consistent• Overall signal availability is 91.7%• Since February 2007, availability is 99.8%• 14th August 2008 - switch to redundant payload to
monitor redundant RAFS long term performance

April 26th - Launch from Baikonur
April 27th - Separation from Fregat- Telemetry acquisition- Solar Array deployment- Successful Sun Acquisition
April 28th - Transition to Earth Acquisition Mode
May 5th - Spacecraft in Nominal Mode- Payload ON (without Signal in Space)
May 5th – 7th - Payload-A commissioning
07 May 2008 00:04:56 First ever in-orbit CBOC transmission
June 9th - Payload-B commissioning
July 10th - successful In Orbit Test Review
Payload In Orbit Test using Redu and Chilbolton stationscompleted with excellent results
GIOVE-B In Orbit Status
GIOVE-B Payload In Orbit Testing• Performance Measurements:
– EIRP– Center Frequency– Modulated Spectra– In Band Unwanted Spurious– Out of Band Unwanted Spurious– Septentrio Receiver
Auto Correlation Functions
• In Orbit Test campaign confirms that the performance of both payloads has not been modified during launch and is in line with ground test results
Examples: Power Spectrum Envelope• E1 BOCc(15,2.5) + CBOC

GIOVE RAFS and PHM stability
GIOVE-B Passive Hydrogen Maser
PHM• Successful 2400+ operating hours in orbit and
4 switch-on sequences• Apparent short-term stability is the best ever observed
from space• Medium-term stability affected by periodic oscillations,
also observed on some GPS satellites• Extremely low frequency drift, no frequency jumps so far• 95% clock prediction error is:
~ 0.5 nsec after 100 min (~15 cm ranging error)~ 2 nsec after 1 day (~ 60 cm ranging error)

IOV Mission
Risk reduction prior to full system deployment:
• Verification of:– Space, ground and user components, incl. interfaces– Navigation Processing– Integrity processing regarding the establishment of Signal
in Space Accuracy and Integrity Flag confidence levels, characterisation of feared events and Time To Alertanalysis
– Operational procedures– Adequacy of the siting requirements
• Analysis of system performance for refinement of Full Operational Capability
• User Equivalent Range Error budget characterisation
IOV status• IOV figures:
– started 21 December 2004– Thousands of engineers working all over Europe– > 400 subcontracts
• Technical baseline consolidated• ESA System Prime & Segment contracts novated end 2007• Galileo Misson Segment & Galileo Control Segment CDRs
completed 2Q08• Ground Segment facilities deployment started mid 2008• Payload EM integration & CDR ongoing• Satellite EM integration has started• System Preliminary CDR 4Q08• Satellite CDR 2Q09• System CDR mid 09
Space Segment Development StatusUp to End 2008: – CDR Closeout for all P/L & P/F equipment– Delivery of most equipments for EM
satellite– Validation activities (compatibility tests,
security accreditation)– Qualification of STM satellite– Qualification of SM satellite
(mainly for launcher dispenser testing)– EM payload testing– EM flat-sat testing
Overall Spacecraft:
730 Kg / 1.8 kW class
Mid-Term Activities:• EM satellite integration & testing (Jan 09)• Space Segment CDR (March 09)• Start of PFM satellite integration & testing (March 09)

Galileo Programme Status
Message to the GNSS community:
• Europe’s contribution to GNSS is well under way - every 2nd year a new Galileo launch campaign starts
• Together we win - interoperability is not an option – it is the baseline
• The challenge is NOT to be better butTO BE THERETO BE IN TIME
