DEIS UAV: GNC Design and avionics implementation issues.

Guidance Navigation and Control (GNC) system of an Unmanned Aerial Vehicle (UAV). The vehicle, thanks to a partially autonomous flight capability, aims to be a very low cost and compact solution to perform significant flight test of general GNC algorithms or as a platform for mission oriented experiments, compared to very expensive aircraft based flight tests. The development activity includes the project, the synthesis and the assembly of the on\u2013board avionics equipment, together with the software implementation for data collection and some basic GNC algorithms. A demonstrative application will be the test of some integrity monitoring functions and algorithms with the use of data collected during some flight
