EGNOS
  • The European Geostationary Navigation Overlay Service
  • The official start of operations- on 1 October 2009
  • 3 satellites- AOR-E (PRN120), IOR-W (PRN 126) and (PRN 124)
  • signal-in-space is broadcast by Geostationary Earth Orbit (GEO) satellites in the L1 frequency, centered at 1575.42 MHz.
  • More than 40 ground stations
slide3
WAAS
  • The Wide Area Augmentation System
  • Space segments- multiple geosynchronous communication satellites(Inmarsat-4 F3, Telesat'sAnik F1R, and Intelsat's Galaxy 15)
  • Ground segments- 38 Wide-area Reference Stations (WRS), 3 WAAS Master Station (WMS), 6 Ground Uplink Stations (GUS), 2 Operational Control Centers (OCC)
  • The user segment is the GPS and WAAS receiver
  • Provides ranging signals transmitted by GEO satellites
slide4
MSAS
  • Multi-functional Satellite Augmentation System
  • Space segment contain two satellites: MTSAT-1R and MTSAT-2
  • The MSAS Ground Segment is composed of four Ground Monitor Station (GMS) that collect information on the GPS and MTSAT signals
  • The MSAS user segment is the GPS and SBAS-enabled receiver
slide5
VOR
  • VHF omnidirectional radio range
  • short-range radio navigation system for aircraft, enabling aircraft to determine their position
  • VOR stations broadcast a VHF radio composite signal
  • A VOR ground station sends out a master signal, and a highly directional second signal that varies in phase 30 times a second compared to the master.
  • The identifier is typically a two- or three-letter string in Morse code.
slide6
DME
  • Distance measuring equipment
  • Aircraft use DME to determine their distance from a land-based transponder by sending and receiving pulse pairs
  • The ground stations are typically co-located with VORs
