The EGNOS System Test Bed (ESTB) interrupted transmission on PRN 131 starting from Friday the 27th of May 2005. Consequently, the SISNeT platform has a new configuration since that date. In particular, the SISNeT platform is monitoring the AOR-E (PRN120) Geostationary satellite, instead of IOR (PRN 131). The PRN120 transmission is accessible at the usual IP address 131.176.49.142, at the usual port 7777 and employing the current SISNeT Data Server Version 2.1. The test version of the SISNeT Data Server V3.0 (previously available at port 7778 for testing purposes) is still accessible, providing access to the ESTB messages obtained directly from the ESTB CPF in Honefoss (Norway).

In the coming days, the ESTB signal will become available again through PRN 120. Therefore, once this change is implemented, you will be able to find:

- ESTB signal obtained from GEO PRN 120 at port 7777, using Data Server v2.1
- ESTB signal obtained from the ESTB CPF at port 7778, using Data Server v3.0
