The aster mission: Exploring for the first time a triple system asteroid
(2011-12-01)
2001 SN263 is a triple system asteroid. Although it was discovery in 2001, in 2008 astronomical observation carried out by Arecibo observatory revealed that it is actually a system with three bodies orbiting each other. ...
Batch, sequential and hybrid approaches to spacecraft sensor alignment estimation
(Amer Astronautical Soc, 2003-07-01)
Two Kalman-filter formulations are presented for the estimation of spacecraft sensor misalignments from inflight data. In the first the sensor misalignments are part of the filter state variable; in the second, which we ...

Dynamics of a spacecraft and normalization around Lagrangian points in the Neptune-Triton system
(Elsevier B.V., 2008-11-17)
The problem of a spacecraft orbiting the Neptune-Triton system is presented. The new ingredients in this restricted three body problem are the Neptune oblateness and the high inclined and retrograde motion of Triton. First ...

Orbital maneuvers to form a constellation of small satellites from a single large spacecraft
(2019-11-04)
The main goal of the present paper is to show how to form a constellation of small satellites when all small satellites leave from a larger spacecraft. It is assumed that they will all stay in a planar formation, in the ...
Estimation of the radiation hazard to a spacecraft passing the van allen belts in a low thrust transfer
(2017-01-01)
A spacecraft transfer from a low Earth orbit to outside the Earth sphere of influence using solar electric propulsion is considered. The spacecraft crosses the Van Allen belts many times during the transfer, what can damage ...
Effects of the Eccentricity of a Perturbing Third Body on the Orbital Correction Maneuvers of a Spacecraft
(Hindawi Publishing Corporation, 2014-01-01)
The fuel consumption required by the orbital maneuvers when correcting perturbations on the orbit of a spacecraft due to a perturbing body was estimated. The main goals are the measurement of the influence of the eccentricity ...
