The detection and identification of Resident Space Objects (RSOs) from survey tracks requires robust efficient orbit determination methods for the association observations same RSO. Both Initial Orbit Determination (IOD) (OD) perform orbital estimation in which relies. choice proper IOD OD is essential whole data association, since they are charge providing required to evaluate figure merit ass...

Any future space debris removal or on-orbit servicing mission faces the problem of the initial relative orbit determination of the servicing satellite to the noncooperative target. In this work we analyze the relative navigation accuracy that can be achieved in low Earth orbit, by using ground-based orbit determination from radar tracking measurements for the target, and classical GPS-based orb...

A combined algorithm which has global and local optimization capabilities is applied to a statistical orbit determination problem. The objective is to estimate initial states of a nearearth satellite nonlinear dynamical system, as well as unknown parameters, by using discrete observations. A particle swarm optimizer is the selected global search tool, and it is used in the first phase to obtain...

Here we revisit an initial orbit determination method introduced by O. F. Mossotti employing four geocentric sky-plane observations and a linear equation to compute the angular momentum of observed body. We then extend topocentric observations, yielding quadratic for momentum. The performance two versions are compared through numerical tests with synthetic asteroid data using different time int...

A method to deal with uncertainties in initial orbit determination (IOD) is presented. This is based on the use of Taylor differential algebra (DA) to nonlinearly map the observation uncertainties from the observation space to the state space. When a minimum set of observations is available, DA is used to expand the solution of the IOD problem in Taylor series with respect to measurement errors...

Situational awareness of Earth-orbiting particles is highly important for future human activities in space. For optical observations of debris, multiple observations must be combined in order to determine the orbit of the observed object. It is generally uncertain, however, whether two arbitrary tracks are of the same object, and solving this problem can be computationally intensive. In this pa...

The uncertainty region associated with short arcs is typically large, making the initialization of orbit estimators a challenging task. In this work we propose a method to reduce the size of the uncertainty region using automatic domain pruning. The initial orbit and its confidence region are obtained by using a differential algebra-based initial orbit determination algorithm and a least square...

Abstract Near-Earth Object (NEO) initial orbit determination typically uses astrometric measurements during a close approach over time window much shorter than the orbital period of NEO. The is only weakly determined with dominant uncertainties in distance NEO from Earth. Topocentric allow us to estimate distances using observed nonlinear motions NEOs relative observers, which come motion Earth...
