System Description
magicSBAS can process observation data from a regional network of reference stations to generate wide area SBAS corrections and integrity parameters for GPS, GLONASS, GALILEO and COMPASS, fully compliant with SBAS international standards such as RTCA/DO-229D and ICAO SARPs.
One of the key advantages of magicSBAS is the capability to process raw data in standard formats like NTRIP, RINEX, EDAS or EGNOS format. The NTRIP protocol in particular is a widely extended, open non-proprietary protocol designed to disseminate GNSS streaming data to stationary or mobile users over the internet and is supported by most of the commercial dual-frequency receivers. There are currently hundreds of Continuous Operating Reference Stations (CORS) worldwide providing data in this format that can be used together with magicSBAS to quickly evaluate the feasibility of an SBAS in nearly any region.
The magicSBAS augmentation message can be disseminated to users via internet, using the SISNeT protocol, or can be made available in binary format for broadcasting through a supported GEO satellite provider. magicSBAS also offers the capability to emulate virtual DGPS stations producing local corrections in RTCM SC-104 v2.3 format.
magicSBAS can be run both in real-time and post-processing modes. In real-time mode, magicSBAS can be used to provide an early pre-operational SBAS service that could be used for non-safety critical applications like mapping, precision agriculture or multi-modal transport. In fast post-processing replay mode, magicSBAS is the ideal tool to support SBAS engineering and feasibility studies.
The magicSBAS product suite includes a real-time service monitor and two performance analysis-modules called magicGEMINI and eclayr. Using these modules, the operator can perform a comprehensive set of performance analysis including accuracy, integrity, service continuity and availability.
