In order to solve the problem of information interaction and communication delay in the application of unmanned aerial vehicle(UAV) formation flight based on global navigation satellite system(GNSS) high precision relative positioning, the design of network topology of the formation flight is optimized to realize the information interaction of all members and minimize the communication cost. Then, a new communication channel access mechanism is proposed. Finally, a formation flight simulation of 16 aircrafts is performed to evaluate the communication network and relative positioning performance. Results show that the end-to-end communication delay among formation members is less than 20 ms. The relative position accuracy can reach sub-decimeter when the total delay of communication and carrier phase difference processing is less than the time interval of relative position sensing, and the sensing error is related to the delay and vehicle maneuver.
