Innovative methods of correlation and orbit determination for space debris
We propose two algorithms to provide a full preliminary orbit of an Earthorbiting object with a number of observations lower than the classical methods, such as those by Laplace and Gauss. The first one is the Virtual debris algorithm, based upon the admissible region, that is the set of the unknown quantities corresponding to possible orbits for objects in Earth orbit (as opposed to both inter...
متن کامل(Preprint) AAS 14-204 INITIAL ORBIT DETERMINATION, DATA ASSOCIATION, AND ADMISSIBLE REGIONS OF SPACE OBJECTS USING MAGNETOMETERS
Magnetometer-based detection and characterization of space objects is motivated and challenges are discussed. Observable constants of motion with and without charge screening are derived in detail. Batch filtering methods are proposed to estimate the observable space object states. A novel application of orbit and detection constraints is used to generate admissible region boundaries for unobse...
متن کاملSpace debris attitude simulation - ιOTA (In-Orbit Tumbling Analysis)
Today, there is little knowledge on the attitude state of decommissioned intact objects in Earth orbit. Observational means have advanced in the past years, but are still limited with respect to an accurate estimate of motion vector orientations and magnitude. Especially for the preparation of Active Debris Removal (ADR) missions as planned by ESA’s Clean Space initiative or contingency scenari...
متن کاملSpace Debris: Flux in a Two Dimensional Orbit
The debris circling the Earth has become an important environmental problem. In particular it creates nonnegligeable risk for spacecraft and satellites. This paper discusses a method to bound the rate of passage of objects through an arc segment in the plane of motion, given random initial conditions for the orbiting object. An advantage of the approach of this paper is that the initial conditi...
متن کاملAstronomy and Astrophysics Orbit Determination for next Generation Space Clocks
In this paper, we study the requirements on orbit determination compatible with operation of next generation space clocks at their expected uncertainty. Using the ACES (Atomic Clock Ensemble in Space) mission as an example, we develop a relativistic model for time and frequency transfer to investigate the effects of orbit determination errors. We show that, for the considered orbit error models...
