  EGNOS – European Geostationary Navigation Overlay System   Part of the world-wide Satellite-Based Augmentation Systems (SBAS) to the U.S. Global

Positioning System (GPS), the Russian GLONASS System and European Galileo system   An initiative of the European Commission (EC) and the European Space Agency (ESA) to

build a civilian component to the military navigation systems of GPS and GLONASS   Provide integrity and high availability and continuity to the (aeronautical) users; improve

accuracy of single-frequency navigation receivers   Other SBAS elements are WAAS (US, Canada Anik 1R) and MSAS (Japan MTSAT-1R, 2)

  Three GEO satellites providing EGNOS signals are currently on orbit (Inmarsat 3F2, Inmarsat 4F2 and ESA Artemis satellite)

  Ground infrastructure deployed   EGNOS Satellite operations

  Autonomous network of monitoring stations located throughout Europe monitor all visible GPS and GLONASS satellites

  Data collected by monitoring stations are processed to generate integrity messages and GPS/GLONASS/Galileo clock and ionospheric correction data

  EGNOS messages uplinked to satellites and down to EGNOS users via L1 and E5 channels   EGNOS certified for non-safety of life (“open service”) applications earlier this month   To be certified later this year for safety of life non-precision approach and approaches with

vertical guidance (APV) aeronautical applications   EC solicited additional GEO assets to replace the existing satellites

  SES providing one such asset on Sirius 5

EGNOS Signal and Message Structure

  Specifications in RTCA MOPS DO229   EGNOS Signal in Space (SIS) is broadcast on GPS L1 (1575.42 MHz)

  With Sirius 5, EGNOS SIS will broadcast on L1 and E5 (1191.795 MHz)   GEOs use GPS-like PRN code

  PRN 120-138 assigned for use for SBAS satellites   Data rate 250 bits per second

  5 times faster than GPS data rate   Utilizes Forward Error Correction (FEC) coding   1 message = 250 bits = 1 second   250-bit message structure

  8-bit message preamble (for data acquisition purposes)   6-bit message type identifier (0 – 63)   212-bit message data   24-bit message parity (Cyclic Redundancy Check)

  Message types include GEO-do-not-use, fast corrections, user differential range error (UDRE) / integrity, slow corrections, ionosperic corrections, etc.
