Research on Spherical Satellite Signature Effect on Satellite Laser Ranging Precision [PDF]

open access: yesProceedings of the International Conference on Information Technology and Electrical Engineering 2018, 2018
Based on the principle of satellite laser ranging (SLR), the effect of spherical satellites signature on the ranging accuracy is investigated and the distribution of echo photons reflected from spherical satellite corner reflectors is analyzed. The theoretical results indicate that the satellite angle reflector has significant influence on the ...

Anisotropic Satellite Galaxy Quenching: A Unique Signature of Energetic Feedback by Supermassive Black Holes? [PDF]

open access: yesAstrophysical Journal Letters, 2023
The quenched fraction of satellite galaxies is aligned with the orientation of the halo's central galaxy, such that on average, satellites form stars at a lower rate along the major axis of the central.

Glonass Laser Ranging Accuracy With Satellite Signature Effect

Surveys in Geophysics, 2001
GLONASS satellites have been tracked by the worldwide laser ranging networkas well as by the GLONASS-borne microwave-based technique. Owing to thelarge size of their corner cube reflector arrays, the amount of ranging data is enough to determine their orbits from laser ranging data alone. We found, however, that the large size of the array affected the

Signature Variations Due To Atmospheric And Topographic Effects On Satellite MSS Data Over Rugged Terrain

International Geoscience and Remote Sensing Symposium, 'Remote Sensing: Moving Toward the 21st Century'., 2005
A model for the radiance applicable to remote sensing of mountainous terrain is described. T his radiance model includes the r adiation arising from adjacent terrain outside t he instantaneous field of view (IFOV) of the sensor. The atmosphere is treated as the optically t hin, horizontally uniform slab layer bounded by non-homogeneous Lambertian ...

Satellite propulsion spectral signature detection and analysis through Hall effect thruster plume and atmospheric modeling

SPIE Proceedings, 2016
Space Situational Awareness (SSA) is of utmost importance in today's congested and contested space environment. Satellites must perform orbital corrections for station keeping, devices like high efficiency electric propulsion systems such as a Hall effect thrusters (HETs) to accomplish this are on the rise.
