  1. Test of Seres receiver using EGNOS signal Joanna Czapska joanna.czapska@gmail.com Warsaw University of Technology Faculty of Geodesy and Cartography

  2. Seres receiver

  3. The Seres receiver • Uses a new GPS engine • Cooperates with EGNOS, WAAS, MSAS satellite systems • Two modes of operation: • With EGNOS correction • Without EGNOS correction

  4. Description of the test • First part static surveying in Warsaw • One measurement site • Second part static surveying in Józefosław • Four measurement sites

  5. Data received in the first part • Obtained ∆x, ∆y and ∆h • From these calculated R2 and R3

  6. Graph I R2 variation in time with EGNOS correction and without the correction

  7. Graph II R3 variation in time with EGNOS correction and without the correction

  8. Results • Comparison of average distances R2 and R3

  9. Results • Comparison of standard deviations R2 and R3

  10. Comparison of σ-errors for R2 (68%-σ, 95%-2σ, 99%-3σ) Surveing with EGNOS correction Surveing without EGNOS correction

  11. Comparison of σ-errors for R2

  12. Comparison of σ-errors for R3

  13. Results - Summary

  14. Data received in the second part • Obtained geographical coordinates: B, L, H (four points A, B, C and D) Astrogeodetic Obserwatory in Józefosław Astrogeodetic Observatory in Józefosław

  15. Comparison of σ-errors for R2

  16. Comparison of σ-errors for R3

  17. Results - Summary

  18. Site A coordinates obtained with EGNOS correction and without this correction True coordinates H=0,00m With EGNOS H=0,70m Without EGNOS H=1,04m

  19. Site B coordinates obtained with EGNOS correction and without this correction Without EGNOS H=0,89m With EGNOS H=1,07m True coordinates H=0,00m

  20. Site C coordinates obtained with EGNOS correction and without this correction True coordinates H=0,00m With EGNOS H=0,37m Without EGNOS H=0,68m

  21. Site D coordinates obtained with EGNOS correction and without this correction Without EGNOS H=1,28m True coordinates H=0,00m With EGNOS H=1,01m

  22. Conclusion • EGNOS correction improves accuracy of the measurements. • The Seres receiver has very fast start-up and acquisition times. • It is very handy and easy to transport • It is very easy to use

  23. Thank You Have a nice day.
