List of system for radio determination of position

1. List of system for radio determination of position Miroslava Trojanovičová

2. 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

3. 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

4. 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

5. 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.

6. 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
