GPS-SBAS-Based Orbit Determination for Low Earth Orbiting Satellites
International Journal of Aerospace Engineering, 2023 A space-based augmentation system (SBAS) provides real-time GNSS correction signals via geostationary satellites for near-ground GNSS users. To use the SBAS correction for low Earth orbit (LEO) satellites, the correction, especially the ionosphere ...

Authentication of Satellite-Based Augmentation Systems with Over-the-Air Rekeying Schemes
Navigation, 2023 Here we delineate a complete satellite-based augmentation system (SBAS) authentication scheme, including over-the-air rekeying (OTAR), that uses the elliptic curve digital signature algorithm (ECDSA) and timed efficient stream loss-tolerant ...

Anisotropic Stars in General Relativity [PDF]
, 2001 We present a class of exact solutions of Einstein's gravitational field equations describing spherically symmetric and static anisotropic stellar type configurations. The solutions are obtained by assuming a particular form of the anisotropy factor.

Animal Research and One Health, EarlyView.Intensive or organic farming systems may expose pigs to management or environmental challenges. Our preliminary results concluded that organic farming might enhance adaptive immune function, showing that improvements in welfare can translate into measurable immunological benefits, based on the correlation between welfare assessment and physiological ...
