Unmanned aerial vehicles (UAVs) have been used for increasing research applications in atmospheric measurements. However, most current solutions for these applications are based on a single UAV with limited payload capacity. In order to address the limitations of the single UAV-based approach, this paper proposes a new concept of measurements using...
In this Note, we present a potential field-based sliding surface design principle for spacecraft attitude maneuvers. Based on the proposed design principle, we obtain new results of sliding surfaces using different attitude parameterizations. These new results are shown to be general forms of existing classical sliding surfaces in literature. Furth...
This paper proposes an adaptive sliding mode control law based on dual quaternions for six-degree-of-freedom proximity operations between a chaser and a target spacecraft. Dual quaternion, a new parameterization to simultaneously describe the translation and the rotation of a rigid body, is used to model the relative motions during proximity operat...
In order to increase the Technology Readiness Level of technologies and algorithms for space applications, the emulation of the free-floating nature of spacecraft is required. In order to replicate this free-floating behaviour, the Institute of Space Systems of Technische Universität Braunschweig has recently implemented the Experimental Laboratory...
Time-optimal reorientation maneuver in the presence of complex attitude constraints is important for the spacecraft to quickly respond to missions. However, it is difficult to solve the problem even with direct methods, which results from the fact that a feasible initial guess for direct methods is usually not available. This paper proposes a new m...
To protect functioning satellites and manned vehicles as well as to prevent a cascade effect which might render the Low Earth Orbit (LEO) region unusable in the future, means of analyzing the space debris environment and removing high risk objects are necessary. Having a long heritage in the analysis and simulation of the debris environment with se...

The goal of this project is to develop new guidance and control algorithms based on dual quaternions for six-DOF proximity operation between a chaser and a target spacecraft.
The goal of this project is to develop attitude planning algorithm and controller to consider the attitude forbidden zone and attitude mandatory zone during the spacecraft reorientation.
The Institute of Space Systems at the Technische Universität Braunschweig compiled a list for objects that are posing great risk of being fragmented, based on their environmental criticality. Active debris removal is considered for these objects. Such elaborate and costly missions have to be planned carefully to fulfill their purpose and should not create a safety issue in case of unexpected failure or dysfunction. In this project several navigation and control techniques are investigated to achieve safe and stable formation flight with a non-cooperative target.
