  1. PNT Advisory Board Nov 2009 Arve DimmenDirector Maritime Safety Norwegian Coastal Administration

  2. IMO e-navigationWork programme

  3. GPS + GLONASS = approx 50 satellites Combined systems improve availability of satellite navigation in situations where part of the sky is blocked.- Urban Canyons- Offshore structures- Fjords Advantages of combined GPS and GLONASS PPP - experiences based on G2, a new service from Fugro IAIN 2009 Stockholm

  4. Conclusions • First real-time GPS/GLONASS PPP service • Developed by Fugro in cooperation with ESA/ESOC • Test results confirm decimetre level accuracy • GLONASS improves availability, robustness and convergence time Future Galileo, … Advantages of combined GPS and GLONASS PPP - experiences based on G2, a new service from Fugro IAIN 2009 Stockholm

  5. Glonass status The next slides comes from: 13-th International Association of Institutes of Navigation World Congress, 27-30 October, 2009, Stockholm, by Sergei Revnivykh

  6. GLONASS Improvement Events In 2007-2008 12 GLONASS-M satellites launched 1st phase of Ground Control modernization Refined geodesy reference implemented (PZ-90.02) 19 GLONASS-M Satellites in orbit (two civil signals inL1 и L2) Next launches (delayed): December 2009 3 “Glonass-M” sats 1-st quarter 2010 3 “Glonass-M” sats Блок 36. 26.10.2007 Блок 37. 25.12.2007 Блок 38. 25.09.2008 Блок 39. 25.12.2008 9

  7. GLONASS Accuracy • GLONASS accuracy has 5 time improved for last three years 20.02.2006 25 m (1 sigma) • Now it is the same order of GPS • Next improvement phase is expected by 2011 20.02.2007 18 m (1 sigma) 20.02.2008 15 m (1 sigma) 20.02.2009 5-7 m (1 sigma) 10

  8. GLONASS Strategy Planning Number of operational satellites • Full constellation deployment in 2010 • Ground Control Segment modernization • New GLONASS-K satellite (with improved performance) IOV start by 2010 • GLONASS will continue transmitting existing FDMA signals • Additional new CDMA signals since GLONASS-K deployment • GLONASS performance competitiveability provision plan • GLONASS Federal Program extension until 2020 11
