Cover Story: The use of autonomous drones and particularly beyond visual line-of-sight (BVLOS) flying has increased in recent years. This is offering new possibilities to develop efficient drone-based applications. Due to possible disruptions in GNSS positioning, redundant positioning systems are required to ensure reliable operation. In this study, a new visual–inertial sensor suite was developed to enable visual–inertial odometry (VIO)-based positioning at high flying altitudes. Empirical testing of the system was carried out at flying altitudes of 40–100 m. Results showed that the proposed VIO-based positioning system could be used as a redundant system for high flying altitude operations. The data collected for the study are openly shared to enable further research and development. View this paper
