This paper describes a reference trajectory generating function of the D-SEND#2 vehicle. The function is composed of two parts. The first one is to output appropriate commands based on the flight trajectory data which was designed beforehand to realize it on the actual flight in real-time. The second part is a real-time trajectory prediction method, and it compensates for the differences between the actual flight conditions and the design conditions. The designed function was evaluated using single error analysis and Monte-Carlo simulation (MCS). All cases in single error analysis succeeded, and the result of MCS was the success rate at 98.1%. It was found that the function has only a little tolerance for the uncertainty of steady wind and the model error of drag coefficient because the vehicle has no engine or devices for velocity control.
