Hemav is a technology-based start-up that offers aerial services with UAVs (Unmanned Aerial Vehicle). One of them is precision agriculture, where remote-sensing techniques combined with the use of several kinds of cameras (multispectral, IR, thermal...) generate maps containing information such as vigor, soil and irrigation determination. In order to offer the best quality of service to their clients, they want to enhance their current prototype by increasing its efficiency and autonomy as well as collecting more telemetry data for monitoring purpose in order to make it safer. Additionally they would also like to produce an agriculture optimized platform. In that context, the scope of this project would be to improve the actual prototype in terms of efficiency, autonomy and telemetry in order to produce a new UAV family optimized for agriculture purpose.
