  1. Anonymous Traffic Collision Avoidance System (ATCAS) by David Bonatz CS 410 09/17/2007

  2. Societal Problem The current collision avoidance system (TCAS II) costs on average $200,000 per aircraft,3 and it is only capable of performing vertical advisories to avoid collisions.

  3. My Solution: ATCAS It will be more reliable. It will be capable of both vertical and horizontal avoidance advisories. It will be cheaper. It can be used on more aircraft.

  4. How TCAS II Works = Interrogation = Transponder

  5. How ATCAS Works = Transponder = Receiver

  6. ATCAS versus TCAS II ATCAS TCAS II Needs at least a 32 bit transmission Needs other crafts Squawk ID Uses 5 receivers Expected to cost from $10,000-$50,000 Can create horizontal course advisories Needs at least a 64 bit transmission2 Needs other crafts Squawk ID, flight path, and location4 Uses 1 receiver Can cost from $50,000 to $250,000 Cannot create horizontal course advisories

  7. Advantages and Disadvantages Advantages: -Less clutter of transponder signals -Cost affective for small aircraft -Can use swarm intelligence to avoid other craft Disadvantages: -Uses 5 receivers to triangulate other aircraft -Unable to get more detailed information

  8. Swarm Intelligence1

  9. Cost Break Down 5 Receivers: $800 each = $4,000 1 Computer: $500 each = $ 500 Instillation: $1,000-5,000 = $3,000 Software: $500 = $ 500 Unexpected Costs: = $2,000 Total = $10,000

  10. Can versus Should Can: -Society has the technology.-A small computer can easily handle the work.-Airplanes are capable of handling additions of new systems. Should: -It will reduce number of mid air collisions.-It will reduce insurance costs.-It is cheaper then current collision avoidance systems.-More aircraft can participate in the system.
