Systems and methods determine at least one air data parameter, such as an angle of attack (AOA), an angle of sideslip (AOS), a total pressure (pt), and/or a static pressure (ps), from information provided by four pressure sensors coupled to four ports on a surface of a vehicle. Each of the ports may be defined by at least a unit vector, wherein the unit vectors are oriented in different planes.
