13: Orbit Determination and Prediction Techniques
Oral presentation at the conference
Upper stages of rockets are large objects, which contain components that are known to be able to survive atmospheric re-entry. Such surviving material, for example propellant tanks, will impact Earth’s surface and might cause ground casualties. Predicting the satellite re-entry, and thus also impact location is notoriously difficult; re-entry prediction is associated with uncertainty in the...

Since the first orbital launch back in 1957, the population of space debris in orbit around the Earth has steadily risen.
As the orbital debris population grows, the likelihood of catastrophic phenomena like the collision between two orbiting objects increases. In order to limit the proliferation of space debris in orbit, a great number of standards, guidelines and even laws have been put...

In order to guarantee safe operation of satellites, space object catalogues must be build-up and maintained. The catalogues should be complete, i.e. contain sufficiently accurate and frequently updated orbital states for all required objects.
In theory, completeness of the catalogue is achieved by designing the radar in a way that a major fraction of the object population is considered...

MONTE (Mission Design and Operations Navigation Toolkit Environment) is an astrodynamic toolkit produced by the Mission Design and Navigation Software
Group at the Jet Propulsion Laboratory. It supports operational orbit determination
and flight path control for deep space and Earth orbiting flight missions, as well as providing an array of tools that can be used in mission design and...

Close encounters with massive bodies, such as planets or Jupiter/Saturn's satellites, make the orbit of any asteroid or spacecraft chaotic. Moreover, in the case of subsequent encounters the Lyapunov time can become very short. Accurate propagation is required in the orbit determination of chaotic bodies, because it mitigates the exponential divergence of nearby orbits. For example, the impact...

Thanks to high-fidelity ephemeris and detailed gravitational maps, third-body and non-spherical gravitational perturbations can be modeled with sufficient precision for most applications in low-Earth orbit (LEO). On the contrary, owing to severe uncertainty sources and modeling limitations, mathematical models of the main non-gravitational forces – namely, aerodynamics and solar radiation...
