PALU is an innovative startup operating in the Aerospace Market, which provides affordable guidance solutions to improve safety of Rotorcrafts during approach and landing operations, especially in critical situations (poor visibility conditions, reduced space of landing, search and rescue operations... ). Since 2016 we are member of the Helicopter Association International (HAI).ANGELS is actually our most important project; it is a next generation landing system based on ADS-B technology. Since 2014, the ANGELS Project is co-funded by the Horizon2020 Programme of the European Union.
