Techniques of Informatics and Microelectronics for integrated systems Architecture

Inertial navigation systems (INS) for safety-critical autonomous objects such as unmanned vehicles and satellites usually have to cope with position and orientation errors provoked by integrating drift and noise from their inertial sensors. Attitude estimation and control algorithms embedded in INS as well as complementary global navigation satellite system (GNSS)-like technologies act hence to periodically correct object's position and orientation by compensating inaccurate data coming from inertial sensors. Furthermore, INS have to deal with space-to-ground high-energy ionizing radiation effects in their semiconductor devices (e.g. processors and memories) as energetic radiation particles are capable to lead INS's embedded algorithms to failing in properly estimating the object's attitude and controlling safety-critical functions. stAte project aims to investigate high-energy ionizing radiation effects in INS's computing systems, more specifically, during the INS's attitude estimation processing, devising embedded software-level solutions for mitigation of radiation-induced errors and related failures.
