1. ESTB in Maritime, Air and Land applications Jarosław Cydejko, Marek Grzegorzewski, Stanisław Oszczak, Adam Ciećko EGNOS WORKSHOP, 24 September 2004, Kraków

2. The maritime experiments verifying the ESTB performance in Poland: Maritime Academy in Gdynia Maritime Office in Gdynia July 2001 – first tests in Gdynia - focused on the comparision of ESTB performance with other GPS-based methods of satellite positioning, such as maritime DGPS and standalone GPS; April 2002 – tests in Gdynia (East Coast) and Dziwnów (West Coast) –focused on the comparison of ESTB performances observed in different locations on the edge of system nominalcoverage. NB:Tests in static conditions;The receivers’ antennas located in known positions; Simultaneous observations for different systems, modes and locations; August 2003 – maritime tests conducted at sea, in the area of Gdańsk Bay within traffic separation scheme established on the approach waters to Gdynia and Gdańsk Harbours. NB:Tests in dynamic conditions, on vessel navigating at sea; The ESTB position estimations refered to simultaneous RTK GPS observations; Simultaneous observations for different systems and modes;

21. Land navigation tests performed in Central European Countries in 2002 The main goal of performed trials was the use ESTB signal in satellite based navigation. The authors of the report carried out three experiments across the Central European Countries aiming at data collection during car navigation. The tests were performed in August – September 2002. North-East Poland, East Slovakia and North-East Italy were chosen as test areas. With current allocation of RIMS, the area of Poland and Slovakia is on the eastern edge of the predicted ESTB coverage (Figure 1).

GNSS receivers used in the experiments • 2 Ashtech Z-XII geodetic receivers (used for calculation of the OTF car trajectory with one second interval) • 2 NovAtel geodetic receivers with EGNOS option of University of Trieste • Magellan Meridian Platinum handheld - the top model of popular Meridian Series, equipped with EGNOS option.

35. Conclusions The performed tests show that GPS positioning with the use of ESTB correction gives very promising results. Even better than expected. The horizontal positioning of moving vehicles with errors around 1-2 meters would be satisfactory for the majority of users of the satellite navigation systems.

36. Conclusions Slightly lower accuracy was achieved for vertical coordinate. However the average error of around 3-4 meters without fully operating EGNOS system gives good prognoses for the future. Some disruptions of ESTB performance were observed giving false results of positioning, therfore Full Operational Capability (FOC) status of the EGNOS system is essential for user. Untill this time ESTB should be used with care.
