  3. What Is Formation Flight

  4. Applications Of Formation Flights

  5. 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 .

  6. BLOCK DIAGRAM FFIS

  7. 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.
