<p><P>PROBLEM TO BE SOLVED: To provide control in distributed formation within multiple cells of aircraft in formation by using a Traffic Alert and Collision Avoidance System(TCAS) and a Mode-S Data Link Transponder. <P>SOLUTION: The Traffic Alert and Collision Avoidance System (TCAS) is based on receiving and processing Mode-S transponder messages, without requiring for TCAS computer to interrogate transponder of each aircraft under flight within formation (i.e., passive TCAS). The Mode-S transponder provides a TCAS computer with ADS-B Global Positioning System(GPS) squitter data, while TCAS computer receives and processes data without the need for interrogating the transponder of multiple cells in aircraft. Thus, this system allows 2-250 aircrafts during flight in formation, to be safely separated by selectable distances. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
