31. Processing Two Line Element sets to facilitate re-entry prediction of spent rocket bodies from the geostationary transfer orbit

Mr Aleksander Lidtke (University of Southampton)

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...

3. Observation of orbital debris with space-based space surveillance constellations

13: Orbit Determination and Prediction Techniques

Oral presentation at the conference

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...

64. Techniques for assessing space object cataloguing performance during design of surveillance systems

Mr Jan Siminski (ESA/ESOC)

13: Orbit Determination and Prediction Techniques

Oral presentation at the conference

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...

177. MONTE: The Next Generation of Mission Design and Navigation Software

Dr Scott Evans (JPL)

16/03/2016, 14:20

13: Orbit Determination and Prediction Techniques

Oral presentation at the conference

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...

111. New orbital elements for accurate orbit propagation in the Solar System

Dr Giulio Bau' (University of Pisa)

16/03/2016, 14:40

13: Orbit Determination and Prediction Techniques

Oral presentation at the conference

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...

94. Recursive estimation of non-gravitational perturbations from satellite observations

Dr Lamberto Dell'Elce (Université de Liège)

16/03/2016, 15:00

13: Orbit Determination and Prediction Techniques

Oral presentation at the conference

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...
