  • Circular Orbit
    Circular orbit A circular orbit is the orbit with a fixed distance around the barycenter, that is, in the shape of a circle. Below we consider a circular orbit in astrodynamics or celestial mechanics under standard assumptions. Here the centripetal force is the gravitational force, and the axis mentioned above is the line through the center of the central mass perpendicular to the plane of motion. In this case, not only the distance, but also the speed, angular speed, potential and kinetic energy are constant. There is no periapsis or apoapsis. This orbit has no radial version. A circular orbit is depicted in the top-left Contents quadrant of this diagram, where the Circular acceleration gravitational potential well of the central mass shows potential energy, and the Velocity kinetic energy of the orbital speed is Equation of motion shown in red. The height of the kinetic Angular speed and orbital period energy remains constant throughout the constant speed circular orbit. Energy Delta-v to reach a circular orbit Orbital velocity in general relativity Derivation See also Circular acceleration Transverse acceleration (perpendicular to velocity) causes change in direction. If it is constant in magnitude and changing in direction with the velocity, we get a circular motion. For this centripetal acceleration we have where: is orbital velocity of orbiting body, is radius of the circle is angular speed, measured in radians per unit time. The formula is dimensionless, describing a ratio true for all units of measure applied uniformly across the formula. If the numerical value of is measured in meters per second per second, then the numerical values for will be in meters per second, in meters, and in radians per second.

Simulation of Stray Light Contamination page | ii Simulation of Stray Light Contamination Kuntzer, T. Abstract he aim of this work is to quantify the amount of Earth stray light that reaches the CHEOPS (CHaracteris- Ting ExOPlanets Satellite) detector. This mission is the first small-class satellite selected by the European Space Agency. It will carry out follow-up measurements on transiting planets. This requires exquisite data that can be acquired only by a space-borne observatory and by well understood and mitigated sources of noise. Earth stray light is one of them which becomes the most prominent noise for faint stars. A software suite was developed to evaluate the contamination by the stray light. As the satellite will be launched in late 2017, the year 2018 is analysed for three different altitudes. Given an visible region at any time, the stray light contamination is simulated at the entrance of the telescope. The amount that reaches the detector is, however, much lower, as it is reduced by the point source transmittance function (PST). It is considered that the exclusion angle subtend by the line of sight to the Sun must be greater than 120°, 35° to the limb of the Earth and 5° away from the limb of the Moon.

  • Galpy: a Python LIBRARY for GALACTIC DYNAMICS
    Preprint typeset using LATEX style emulateapj v. 12/16/11 galpy: A python LIBRARY FOR GALACTIC DYNAMICS Jo Bovy1,2 Institute for Advanced Study, Einstein Drive, Princeton, NJ 08540, USA; [email protected] ABSTRACT I describe the design, implementation, and usage of galpy,a python package for galactic-dynamics calculations. At its core, galpy consists of a general framework for representing galactic potentials both in python and in C (for accelerated computations); galpy functions, objects, and methods can generally take arbitrary combinations of these as arguments. Numerical orbit integration is supported with a variety of Runge-Kutta-type and symplectic integrators. For planar orbits, integration of the phase-space volume is also possible. galpy supports the calculation of action-angle coordinates and orbital frequencies for a given phase-space point for general spherical potentials, using state-of-the-art numerical approximations for axisymmetric potentials, and making use of a recent general approxi- mation for any static potential. A number of different distribution functions (DFs) are also included in the current release; currently these consist of two-dimensional axisymmetric and non-axisymmetric disk DFs, a three-dimensional disk DF, and a DF framework for tidal streams. I provide several examples to illustrate the use of the code. I present a simple model for the Milky Way’s gravitational potential consistent with the latest observations. I also numerically calculate the Oort functions for different tracer populations of stars and compare it to a new analytical approximation. Additionally, I characterize the response of a kinematically-warm disk to an elliptical m = 2 perturbation in detail.

  • Autonomous Orbit Control Coupled with On-Board Risk Management
    DEGREE PROJECT IN VEHICLE ENGINEERING, SECOND CYCLE, 30 CREDITS STOCKHOLM, SWEDEN 2021 Autonomous orbit control coupled with on-board risk management CLÉMENT LABBE KTH ROYAL INSTITUTE OF TECHNOLOGY SCHOOL OF ENGINEERING SCIENCES 2 Abstract Many satellites have an orbit of reference defined according to their mission. The satellites need therefore to navigate as close as possible to their reference orbit. However, due to external forces, the trajectory of a satellite is disturbed and actions need to be taken. For now, the trajectories of the satellites are monitored by the oper- ations of satellites department which gives appropriate instructions of navigation to the satellites. These steps require a certain amount of time and involvement which could be used for other purposes. A solution could be to make the satellites autonomous. The satellites would take their own decisions depend- ing on their trajectory. The navigation control would be therefore much more efficient, precise and quicker. Besides, the autonomous orbit control could be coupled with an avoidance collision risk management. The satellites would decide themselves if an avoidance maneuver needs to be considered. The alerts of collisions would be given by the ground segment. In order to advance in this progress, this internship enables to analyse the feasibility of the implementation of the two concepts by testing them on an experiments satellite. To do so, tests plans were defined, tests procedures were executed and post-treatment tools were developed for analysing the results of the tests. Critical computational cases were considered as well. The tests were executed in real operations conditions. Keywords Tests, Autonomous Orbit Control, collision risks, station-keeping, control indicators 3 Sammanfattning Manga˚ satelliter har en referensbana definierad enligt deras uppdrag.
