SISNeT is a technology that combines
the powerful capabilities of satellite navigation and the
Internet. The highly accurate navigation information that
comes from the EGNOS (European Geostationary Navigation Overlay
Service) Signal-In-Space (SIS) is now available over the Internet
and in real time via SISNeT.
Specifically, SISNeT gives access to the wide-area differential corrections and the integrity information of EGNOS. The SISNeT project was undertaken by ESA during the second half of 2001. In August 2001, the first prototype of the system was set-up, and the SISNeT concept was successfully validated. Since February 2002, the system has been operational, broadcasting an EGNOS signal through the Internet, as generated by the EGNOS System.
Any user with access to the Internet (usually through wireless
networks - GSM or GPRS) can access EGNOS through SISNeT, irrespective
of the GEO visibility conditions. No EGNOS receiver is needed.
The scientific and engineering communities can benefit hugely
from SISNeT because they can exploit the EGNOS information simply via the Internet.
