However, too sparse or irregular observation data can affect the quality of orbit determination [12].
Characterizing the orbits of SSO's becomes therefore a fundamentally collaborative task, in which the participation of observatories around the world providing this information is mandatory, with enough quality to obtain convergence in the algorithms of orbit determination. This is a reason the Minor Planet Center (MPC) was created, a service of the International Astronomical Union (IAU), whose purpose is to receive and distribute the position data delivered by the observatories around the world that have the MPC code.

Accuracy of the orbit determination dramatically increased during last 25 years and a new study is needed.

However, Analytical Graphics Incorporated's Orbit Determination Tool Kit software allows for ingestion of the ground-based right ascension and declination observations in the topocentric reference frame directly with knowledge of the observing site's location.
The orbit determination system is based on a Global Navigation Satellite System (GNSS) receiver [23-25].
Subjects covered include orbit determination, attitude control and trajectory optimization; space surveillance and small-body orbital dynamics for asteroid missions; space environment, spacecraft guidance and control; interplanetary and small-body missions; formation flying and spacecraft astronomy, and many others.
This software is dedicated to satellite orbit determination and prediction, geodetic parameters estimation, tracking instruments calibration, and many other applications in the field of space geodesy.
In this paper, a robust adaptive Kalman filtering algorithm is proposed, aiming to investigate the influence of the orbit determination errors on the attitude determination.
The satellite orbit determination (OD) estimates discrete observation of the position and velocity of an orbiting object.
