Nowadays, within the space robotics, there is a substantial interest in achieving on-orbit satellite servicing operations autonomously. On-orbit servicing (OOS) requires ability to rendezvous and dock by an unmanned spacecraft minimizing human intervention. This paper is presented like a step in this course. In RoboticsLab, we have developed the RISANAR testbed to simulate scenarios of autonomo...

The advent of Global Navigation Satellite Systems has brought about an additional navigational aid for aircrafts. Due to their complementary error characteristic, various approaches involving Global Positioning System coupled with the Inertial Navigation System have been looked into for complete autonomous navigation and attitude estimation of the aircraft. In this paper, we study, through simu...

This paper presents a GPS receiver satellite/antenna selection algorithm for the Stanford Gravity Probe B Relativity Mission. A Trimble Advanced Navigation Sensor Vector receiver onboard the space vehicle, a fourantenna six-channel GPS receiver, will provide real-time navigation solutions for orbit trim and raw measurements for ground post-processing, both for more accurate position and velocit...

In certain outdoor sports it is desired to capture the trajectory and the dynamics of an athlete with high temporal and spatial resolution, and possibly also high accuracy. This is primarily for training, detailed performance analysis, studying risk, and for research while ranking during competition is typically based on time measurements e.g., using photocells. Due to the virtually unlimited o...
