This paper presents a multi-antenna GNSS solution for a launch vehicle able to provide position and velocity of the launcher continuously, including during the rotation and acceleration phases of flight. The originality of this work is the development of a multi-antenna, multi-constellation (GPS/GALILEO) and multi-frequency (L1/L5) GNSS positioning solution. The multiple antenna configuration is considered in order to keep tracking a sufficient number of GNSS signals during the whole flight. Under these improved visibility conditions, a navigation solution is proposed combining data received from all antennas to estimate the position and velocity of the launch vehicle. The proposed algorithm is an Extended Kalman Filter that uses code pseudoranges and doppler measurements. In the paper, several configurations and combinations are tested and compared.
