Martínez Castillo, Jorge (author)
This thesis studies the dynamics of Phobos, Mars’ bigger moon, as part of the preparation for coming Phobos-bound missions. Existing observations have not been able to properly constrain the interior of the two Martian moons in general and Phobos in particular, being therefore inconclusive about their origin and formation. Thus, on-site...

Precision orbit determination for geodetic applications requires force models even for small perturbations. Radiation from the Sun and Moon is a significant source of perturbation in lunar orbits and inadequate modeling of radiation pressure (RP) can lead to large position errors. This paper describes the short-term effect of RP on the Lunar...

Small solar system bodies have received increasing scientific attention over the past decades. Studying their primitive origins can reveal important insights on the formation of planets, as well as the general evolution of the Solar System. Also their potential threat to life on Earth upon collision and their potential to act as stepping stones...

Competitive with classic inertial sensors, quantum gradiometers based on CAI are exceptional new devices, which hold the promise to measure inertial forces with an unprecedented level sensitivity (≈mE/√Hz). Mechanical effects of light pulses are exploited to spatially separate and recombine the wavepackets of cooled atoms, which, thus, interfere...

The Planetary Radio Interferometry and Doppler Experiment (PRIDE) technique has supported the exploitation of Doppler observations of planetary landers from Earth-based stations in many radio science experiments. The precise retrieval of the estimates of the Mars rotation and Orientation Parameters (MOPs) is an important application of the PRIDE...

This thesis project investigates navigational aspects of the upcoming JUICE (JUpiter ICy moons Explorer) mission, which is expected to deliver valuable data products for the scientific study of the Jovian system, and the three Galilean moons Europa, Ganymede and Callisto in particular. One such data product comes from the 3GM radio science...

The Ganymede Circular Orbit Phase (GCO-500) of the JUICE mission will be<br/>the first time a moon beyond Earth’s will be orbited for an extended period of 9 months. This orbit phase, due to its close proximity, opens the window to more accurately determine the spacecraft orbit and thereby unambiguously characterize the interiors of the Galilean...

Gasman, Danny (author)
Interactions between tidal migration and the encounter of mean motion resonances (MMRs) have widely been used in attempts to explain unexpectedly young surfaces and high free eccentricities of moons. A driving variable in this process is the planetary quality factor (Q$), which has so far been assumed to be constant throughout the system....

Laser communication offers high data rates and more bandwidth capacity compared to radio but is also advantageous in terms of power and volume. However, the required pointing accuracy and atmospheric influence pose stringent requirements on the system which form the main challenges for this type of communication. This is where laser ranging...

Mol, Jelle (author)
Planetary observational accuracy increases and the dynamical modeling of tidal behaviour has to follow. In this thesis, a newly developed method (Correia et al. 2014; Boue et al. 2016) to deal with tidal interactions in a 2D two body problem is validated and for the first time applied to Solar system dynamics on a short time-scale. This method...

van der Zwaard, Rens (author)
Tests of General Relativity are often done in the Solar System by using tracking data from interplanetary space missions, to measure the perturbation on the orbits of the planets that is predicted by General Relativity. The next best opportunity for such a test is the BepiColombo spacecraft by the European Space Agency, which will arrive at...

For any space mission, the communication subsystem is an indispensable part of the satellite that carries the payload. Traditionally, on-board antennas transmitting Radio Frequency (RF) waves to the receiver have been used. Nowadays, laser communications is becoming increasingly popular due to its potential to become a license-free, secure and...

This thesis work has been motivated by the growing interest in small-spacecraft small-body missions and more specifically inspired by a proposed mission to the largest Martian Trojan (5261) Eureka. This binary asteroid represents a promising target for a planetary mission, as a better understanding of its formation and evolution would provide...

The Rotation and Interior Structure Experiment (RISE) on the InSight lander and the LaRa experiment on the ExoMars platform will provide precise measurements (accuracies of a few mas) of the rotation of Mars, in terms of the Mars rotation and orientation parameters (MOP). These parameters include the rate of precession and the amplitudes of the...

The Jupiter Icy moons Explorer (JUICE) will generate ephemerides of the Galilean moons to assess their ability to sustain live. However, determining the ephemerides only using radiometric tracking (acquired using PRIDE and 3GM) results in an unstable solution which is related to the absence of flybys of especially Io, such that its dynamics can...

Fodde, Iosto (author)
Currently one of the major drawbacks of interplanetary travel is the cost of these types of missions. Mission to extra-terrestrial bodies require a large amount of propellant to complete, which often takes up a large part of the mass budget of the spacecraft. This requires larger launchers to be used to get the spacecraft into the required orbit...

With the introduction of Interplanetary Laser Ranging (ILR), the acquired tracking measurements accuracy of planets can be improved drastically (up to a few millimeters) which can result in an improvement in planetary ephemerides of not only the planet which is the target of laser ranging but also other bodies in the solar system due to...

Currently, an increasing amount of debris is floating in Low Earth Orbit (LEO) endangering space operations. To limit the contribution of non-operational satellites to the space debris problem a semi-controlled end-of-life de-orbit strategy can be employed. In this strategy the satellite is controlled from the end-of-life orbit down to low...

As part of the ESA mission to Jupiter and Ganymede carried out by the Jupiter Icy Moons Explorer (JUICE) spacecraft, the Ganymede Laser Altimeter (GALA) will determine the topography and detect Ganymede’s tidal degree-2 signal in order to investigate the existence of a subsurface ocean and constrain its thickness. To deliver successful...

Gastaldello, N. (author)
The JUICE spacecraft is an ESA mission to the Jovian system that will be launched in 2022. It will collect scientific data about Jupiter and its Galilean moons thanks to a flyby tour of Europa, Ganymede, Callisto and a final Ganymede orbiting phase. A high number of flybys will be performed with minimumaltitudes of 200 km. The tracking of the...
