Austrian EGNOS Data Server
Industrial and scientific research and development to implement an EGNOS data service for Austria, which
shall provide higher positioning performances.
The Austrian EGNOS data server (OEGNOS – Österreichischer EGNOS Datenserver) provides an EGNOS correction data
service especially tailored to the requirements in Austria. For that purpose, improved EGNOS correction data
are provided to the users via a terrestrial communication connection. Especially in Austria, this service will
induce a significant added value due to the challenging topography and thus the arising EGNOS satellite signal
shading. By the integration of local meteorologic parameters (atmospheric corrections – ionosphere, troposphere),
derived from real measurements, the quality of the EGNOS correction data is improved significantly. Therefore,
the EGNOS correction data are decoded, supplemented by the computed local ionospheric and tropospheric corrections,
encoded into an RTCM format, and provided via an authenticated GSM/GPRS (TCP/IP) connection. Due to the improved
absolute accuracy of the single point positioning new application areas arise (e.g. agrarian area determination,
special inland waterway navigation applications, first GPS/EGNOS based driver assistance functions etc.), which
can not be covered by conventional GPS/EGNOS positioning in Austria.
The main goal of the project is the industrial and scientific research and development regarding the generation
of an Austrian EGNOS data service which provides improved accuracy. Thus, a data server and a test user terminal
will be developed and tested in order to evaluate the complete system. The first version of this service will
cover a local area in the surroundings of Rottenmann (Styria).
A future planned development (at present not part of the project) aims at the back coupling of the test user
terminal. This means that the approximate coordinates (single point position solutions) of the terminal are
transmitted to the EGNOS data server in order to be able to compute, assign, and re-transmit the corresponding
correction set to the test user terminal. Furthermore, the transmission of the improved EGNOS correction data
via a radio broadcasting service is envisaged in order to provide them e.g. for automotive applications.
