A spacecraft attitude kinematics model, attitude measurement model, and filter algorithm are three important parts in spacecraft attitude determination, and a high-precision filtering algorithm is the ...

Abstract: Aiming at the problem that the GNSS/INS integrated navigation system is easily affected by climate and environmental noise in navigation and positioning, and it is difficult to determine the ...

Abstract: Noise cancellation aims to reduce or eliminate unwanted signals from the original signals, such as audio signals, thereby improving signal quality and clarity. A popular method for active ...

The model could uncover quakes that would previously have been dismissed as human-generated vibrations. Cities are loud places. Traffic, trains, and machinery generate a lot of noise. While it’s a ...
