Applications Of Formation Flights

Ground Based Systems

• Previously the information from the formation
  flight would reach ground based instruments and
  then to the flights back again .
• This lead to a number of accidents and failures
  in formations flights , hence NASA came up with
  an Instrumentation System called the Formation
  Flight Instrumentation System (FFIS).
• FFIS makes use of GPS , Extended Kalman filter
  and an interface .

Extended KALMAN FILTER

• The Kalman Filter is a recursive filter which
  estimates the state of a dynamic system from a
  series of incomplete and noisy measurements.
• In this project an extended KALMAN filter is used
  along with GPS( FFIS) to eliminate the need for
  ground based systems information flight.
• We used MATLAB to simulate the results for the
  filter to estimate position, velocity and
  attitude of the next aircraft.
