5. NAVIGATIONAL-AIDS
'ART' of determining the position of an
aircraft over earth's surface and guiding its
progress from one place to another
Nav-Aids used by AAI: Sat.
NDB VOR DME ILS
Nav.

6. NDB: Non Directional
Beacon 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. 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

MEASURING
EQUIPMENTS
System combining Ground Based and

19. SATELLITE
NAVIGATION
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
