- Abstract
- The Aeronautical Earth Stations in Motion (AESIM) operating in the 27.5-29.5 GHz (Earth-to-space direction) frequency band have to protect the fixed and mobile services which is allocated as co-primary basis in the same frequency band, therefore A-ESIM shall not cause unacceptable interference to the stations of fixed and mobile services. Concerning this, World Radiocommunication Conference (WRC-19) developed power flux density (pfd) limits, as protection criteria, for A-ESIM to protect the terrestrial radio stations. To comply with this pfd limit, the A-ESIM need to be operated above a specific altitude with e.i.r.p. characteristics such as transmit power and antenna pattern. This paper introduces a method to examine whether the A-ESIM operation will meet the pfd limitation and to provide the minimum operational altitude for A-ESIM complying with the pfd limitation. Based on the proposed method, simulation considering actual AESIM operation was conducted and the minimum altitudes of AESIM were determined within the service area not to cause unacceptable interference to the terrestrial services.
