Research Projects

All the research projects that the Space Technology Centre has been involved in are described below:

LIDAR-GNC

PANGU simulated Martian surface

PANGU simulated Martian surface

The LIDAR-GNC research was done as a sub-contractor to EADS Astrium SAS. The aim of this work was to extend PANGU to cover realistic Martian surface generation including boulders and sand dunes and to simulate a scanning LIDAR sensing the Martian terrain. The LIDAR sensor simulation is capable of simulating a range of scanning LIDAR instruments and takes into account spacecraft motion during the scanning interval. PANGU models and the LIDAR simulation have been integrated in a guidance and navigation control system prototype by Astrium.

SpaceWire-10X Testing

The aim of the SpaceWire-10X Testing project is to test the SpaceWire-10X Router ASIC device under various conditions to ensure there are no problems with the device. This involves the development of a test environment in which it is possible to stress the SpW-10x's operation. Appropriate tests have been devised and these will be performed and the results analysed.

HARVD: High-integrity, Autonomous, multi-range RendezVous and Docking

HARVD VRML Satellite Model

HARVD VRML Satellite Model

The overall objective of the HARVD (High-integrity, Autonomous, multi-range RendezVous & Docking) study is to develop a European capability for autonomous orbital rendezvous and docking. The detailed design of a high-integrity, autonomous, multi-range, rendezvous and docking control system is being developed for future solar system exploration missions. A demonstration system including the onboard GNC hardware and software components is being developed. Its real-time performance and autonomous operation is being evaluated covering far-field to terminal rendezvous. Two types of mission are being examined: planetary sample return and associated rendezvous of return capsule with orbiting Earth return vehicle, and in-orbit servicing of both cooperative and non-cooperative spacecraft.

SpaceWire CODEC Support

The SpaceWire CODEC Support project is aimed to provide updates and support for end users of the SpaceWire CODEC IP. The IP is a synthesisable VHDL model of the SpaceWire data strobe encoder decoder maintained by the University of Dundee, originally developed under the SpaceWire router ASIC project.

NPAL: Navigation for Planetary Approach and Landing

Feature tracking across a sequence of planetary surface images

The University of Dundee worked with EADS Astrium, Galileo Avionica, INETI and SciSys to develop an intelligent camera for vision-based navigation of a planetary lander. This research funded by ESA within the Navigation for Planetary Approach and Landing (NPAL) study was led by EADS Astrium in France. The camera unit performs image processing to select image feature points and to track them from frame to frame. With knowledge of the tracks of several feature points and the linear and rotational acceleration of the spacecraft, provided by an inertial measurement unit, it is possible to reconstruct the path of the spacecraft and to determine its position and orientation relative to a planet’s surface.

Robust Entry Descent and Landing System for ExoMars

FEIC feature tracking on a PANGU generated image sequence

The Robust Entry Descent and Landing System (EDLS) for ExoMars study aims to develop technologies to ensure a safe landing of ExoMars on the surface of Mars. The overall project is being led by LogicaCMG.

The overall project objectives are to:

  • Assess a number of novel but pragmatic and achievable candidate methodologies to:
    • Improve the accuracy of a landing from ballistic entry.
    • Reduce the risk of mission failure during the terminal phase.
  • Quantify the impact of key atmospheric variables on the propagation of the injection covariance matrix during entry, descent and landing thereby allowing:
    • A more rigorous approach to be taken to the design of the overall EDLS solution
    • Novel methods for accuracy improvement and risk reduction to be developed in a realistic environment

The principal objective for the University of Dundee was to:

  • Investigate processing of sensor data to estimate the transverse velocity of the lander.


SpaceWire Router ESM006

Details coming soon.

VINSE: Vision-Based Integrated Navigation for Space Exploration

The VINSE (Vision-Based Integrated Navigation for Space Exploration) activity is an EU Marie Curie Outgoing International Fellowship. The Research Fellow is Dr Victor Silva, a former PhD student in the Space Technology Centre at Dundee. Victor is funded to work for two years at the NASA Jet Propulsion Laboratory (JPL) and to then return to Dundee for another year. His research intends to show that the integration/fusion of visual information with inertial measurements can provide robust surface relative navigation suitable for planetary lander missions to many different planetary bodies. The objectives will be achieved through the international collaboration with the JPL, the World’s leading organization on technology for planetary landers and robotic space exploration, and the UoD (University of Dundee), Europe’s leading organization on planet surface and sensor simulation for testing planetary landers.
