Ppt on Communication and Navigation at AIPORT AUTHORITY OF INDIA

  1. 1. TRAINING SEMINAR ON NAVIGATIONAL AIDS AT AIRPORT AUTHORITY OFSUBMITTED TO: INDIA SUBMITTEDProf. S. S. BY:Shekhawat Akshay Kumar ID-09EJCEC010
  2. 2. AAI:PORTFOLIOWorks under Ministry of CivilAviation(MOCA) Construction andIt Air Traffic provides: development Services of airports and air routes ATM CNS
  3. 3. SURVEILLANCE CNS NAVIGATIONALCOMMUNICATION AIDS
  4. 4. COMMUNICATIONWays to Communicate at AAI: Voice Data VHF AFTN HF AMHS
  5. 5. NAVIGATIONAL-AIDSART of determining the position of anaircraft over earths surface and guiding itsprogress from one place to anotherNav-Aids used by AAI: Sat. NDB VOR DME ILS Nav.
  6. 6. NDB: Non DirectionalBeacon relative Provides bearing to the aircraft w.r.t. direction of NDB N equipment irrespective of aircraft heading W Used by aircraft to E help obtain a fix of their geographic NDB location on the surface S of the Earth Most commonly used as "locators" for an instrument landing
  7. 7. VOR: VHF Omni Range A standard ICAO ground based radio navigational aid. Type of short-range radio navigation system for aircraft Enable the aircraft to determine their position and stay on course by receiving radio signals transmitted by a network of fixed ground radio beacons, with a receiver unit. Transmits 30 Hz reference and a variable

  19. 19. SATELLITENAVIGATION Satellite-based augmentation systems (SBAS), such as GAGAN, WAAS, EGNOS and MSAS, complement existing global navigation satellite systems (GNSS) SBAS compensate for certain disadvantages of GNSS in terms of accuracy, integrity, continuity and availability Based on the transmission of differential corrections and integrity messages for navigation satellites that are within sight of a
