To satisfy the demands of civil aviation organizations and other users of satellite navigation systems for high-precision and high-integrity service performance, many countries and regions have established satellite-based augmentation systems (SBAS) referring to the Radio Technical Commission for Aeronautics (RTCA) service standards and agreements.
Airy wave packets constitute a very peculiar type of structured light: during their propagation, their transverse profile undergoes a self-accelerating displacement while it remains shape invariant.They are thus the only non-dispersive beam-type solution to the Helmholtz paraxial equation in free space.Such properties are possible by virtue of thei
Assessing the motion of moving objects from video footage captured using multiple recording devices requires precise timing and location data, itsmajorlook.com which remains equally important in mobile recording systems.Although capturing high-precision clocks and analyzing these images are effective methods for obtaining accurate time information,
