TRANSCRIPT
TACAN (TACTICAL AIR NAVIGATION System)
Accurate within one degree
Provides continuous range and bearing
100 aircraft can receive range at one time
No limit of aircraft receiving bearing information
Signal sent to ground station
Signal sent back to airplane
TACAN equipment required (pricey!)
TACAN measures distance in slant range
Slant range = straight-line-of-sight
Directly over the station DME measures
height above ground
