Relative Positioning Evaluation of a Tetrahedral Flight Formation's Satellites
(2017-10-25)
This paper presents a study about the tetrahedral layout of four satellites in a way that every half-orbital period this set groups together while flying in formation. The formation is calculated analyzing the problem from ...
Zero, minimum and maximum relative radial acceleration for planar formation flight dynamics near triangular libration points in the Earth-Moon system
(Elsevier B.V., 2014-11-01)
Assume a constellation of satellites is flying near a given nominal trajectory around L-4 or L-5 in the Earth-Moon system in such a way that there is some freedom in the selection of the geometry of the constellation. We ...
Natural formations at the Earth-Moon triangular point in perturbed restricted problems
(Elsevier B.V., 2015-07-01)
Previous studies for small formation flying dynamics about triangular libration points have determined the existence of regions of zero and Minimum Relative Radial Acceleration with respect to the nominal trajectory, that ...

Analysis of communication strategies for earth observation satellite constellations
(Institute of Electrical and Electronics Engineers, 2016-06)
Earth observation satellite constellations are arising as a new paradigm with important advantages in comparison with traditional monolithic systems. In particular, the concept of Segmented Architecture proposes to transform ...
Development and Assessment of a Data Set[-2pt] Containing Frame Images and Dense Airborne Laser Scanning Point Clouds
(2017-12-28)
This letter describes the main features of a data set that contains aerial images acquired with a medium format digital camera and point clouds collected using an airborne laser scanning unit, as well as ground control ...
