Imagery Synthesis for Drone Celestial Navigation Simulation

open access: yesDrones, 2022
Simulation plays a critical role in the development of UAV navigation systems. In the context of celestial navigation, the ability to simulate celestial imagery is particularly important, due to the logistical and legal constraints of conducting UAV ...

Geometric Coplanar Constraints-Aided Autonomous Celestial Navigation for Spacecraft in Deep Space Exploration

open access: yesIEEE Access, 2019
Autonomous celestial navigation has been exploited for orbit determination of deep space exploration. Geometric constraints in celestial measurement are the inherent attributes in actual comprehensive autonomous celestial navigation physical systems ...

How Orion's ability to "walk upon the sea" was attributed to Jesus: the astronomical basis for Christ's sea-walk miracle [PDF]

open access: yesArchaeoastronomy and Ancient Technologies, 2018
Irreconcilable differences found in Jesus' "Sea-Walk" narrative imply that it was not based on eyewitness testimony, and therefore must have been founded on some other system of proof.

Rediscovering the celestial cuneiform puns that imparted the "Birth of Pegasus" myth [PDF]

open access: yesArchaeoastronomy and Ancient Technologies, 2017
In a recent article the author has shown that Pegasus' appearance in Greek astronomy - as a Flying Horse severed at the navel - displays a one-to-one correlation with wordplay encrypted in its older, Mesopotamian title as the "Field". The current article

Strapdown Celestial Attitude Estimation from Long Exposure Images for UAV Navigation

open access: yesDrones, 2023
Strapdown celestial imaging sensors provide a compact, lightweight alternative to their gimbaled counterparts. Strapdown imaging systems typically require a wider field of view, and consequently longer exposure intervals, leading to significant motion ...

How cuneiform puns inspired some of the bizarre Greek constellations and asterisms [PDF]

open access: yesArchaeoastronomy and Ancient Technologies, 2016
Many of the Greek constellations catalogued in Claudius Ptolemy's mid-second century Almagest originated in Mesopotamia. Yet numerous other Greek constellations and asterisms do not correspond to Mesopotamian prototypes, and simultaneously display ...

Reflections about the conceptual bases of Geotourism and its sub-segments Space Geotourism, Celestial Geotourism and Astrotourism to create a univocal definition

open access: yesAnais da Academia Brasileira de Ciências, 2023
The concept is part of the essence of a mentally represented element. The concept is part of the process of identification, categorization and description, which allows researchers to define and compare themes between two or more different categories ...

Bulk locality from the celestial amplitude

open access: yesSciPost Physics, 2022
In this paper, we study the implications of bulk locality on the celestial amplitude. In the context of the four-point amplitude, the fact that the bulk S-matrix factorizes locally in poles of Mandelstam variables is reflected in the imaginary part of
