Quantitative Analysis to the Impacts of IMU Quality in GPS/INS Deep Integration
Micromachines, 2015 In the Global Positioning System (GPS)/Inertial Navigation System (INS) deep integration system, the pure negative effect of the INS aiding is mainly the INS navigation error that is independent with the motion dynamics, which determine whether the INS ...

Hierarchical Planning Applied to the Preliminary Design of CubeSats: Nanospace Study
Systems Engineering, EarlyView.ABSTRACT CubeSat design has been already studied and formalized but knowledge representation remains a challenge. The management of human‐learnt knowledge during the process is not an aspect that is often spoken about. This paper discusses the proposal of integrating a hierarchical planning approach with a model‐based one to the open‐source Nanospace ...

A real/fast-time simulator for impact assessment of spoofing & jamming attacks on GNSS receivers [PDF]
In aviation, the impact of threats is becoming increasingly significant, particularly for global navigation satellite system (GNSS). Two relevant GNSS threats are represented by jamming and spoofing. In order to evaluate the technological solutions to counter GNSS attacks, such attacks should be assessed by means of a proper GNSS threat simulator. This
