A method and system for collision avoidance, carried by each aircraft,
includes a miniature MEMS (MicroElectroMechanical Systems) IMU (Inertial
Measurement Unit), a miniature GPS (Global Positioning System) receiver, a
display, a data link receiver/transmitter, and a central processing
system. Each aircraft carries a GPS receiver coupled with a self-contained
miniature IMU for uninterrupted position determination. This position
information is shared with other aircraft over an RF (Radio Frequency)
data link. An intelligent display shows the relative positions of the
aircraft in the immediate vicinity of the host aircraft and issues voice
and flashing warnings if a collision hazard exists. This system provides
situational awareness to the pilot and enhances the safety of flight.
