A new airborne Base Transceiver Station (BTS) service is constructed and verified on a Low Altitude Flying Platform (LAFP). A telecommunication signal relay via LAFP is proposed. To establish effective frequency isolation, the downlink relay falls on the construction of steady Microwave Air-Bridging (MAB) between LAFP and ground E1 optical fiber network. An efficient GPS-to-GPS (G2G) tracking system is designed and implemented using Adaptive Neural Fuzzy Inference System (ANFIS) algorithm for controlling the antenna pointing mechanism. Flight tests using ultra-light aircraft are carried out to verify the microwave link performance with acceptable feasibility and reliability on the proposed LAFP for airborne mobile communication services.
