Abstract
Link margin (LM) analysis has a critical importance on designing and using aeronautical communication (AC) systems. Antenna gains are vital to analyze LM, while gains of airborne antenna are affected by position or attitude of aircrafts. To study the relationship between LM and position or attitude of aircrafts, a method of LM analysis is presented based on coordinate transformation. The coordinate is used to be calculated for elevation and azimuth angles, which are associated with antenna gains. The method is validated in typical scenarios, and the result indicates that the LM calculating model is accuracy and practicable.
