End To End Satellite Servicing And Space Debris Management, Aman Chandra, Himangshu Kalita, Roberto Furfaro, Jekan Thanga

Space Traffic Management Conference

There is growing demand for satellite swarms and constellations for global positioning, remote sensing and relay communication in higher LEO orbits. This will result in many obsolete, damaged and abandoned satellites that will remain on-orbit beyond 25 years. These abandoned satellites and space debris maybe economically valuable orbital real-estate and resources that can be reused, repaired or upgraded for future use. Space traffic management is critical to repair damaged satellites, divert satellites into warehouse orbits and effectively deorbit satellites and space debris that are beyond repair and salvage. Current methods for on-orbit capture, servicing and repair require a large service …

Aircraft-Runway Total Energy Measurement, Monitoring, Managing, Safety, And Control System And Method, Nihad E. Daidzic,

United States Patent, Patent Number US 10,202,204 B1, Date of Patent February 12, 2019.

A total runway safety system (TRSS) and method measures, monitors, manages, and informs flight crew on the progress of takeoffs and landings and of any hazardous runway conditions. In some embodiments, the TRSS measures, monitors, and informs flight crew of longitudinal and lateral runway tracks thus preventing overruns and veer-offs during takeoffs and landings. In some embodiments, backscatter of infrared laser beams emitted by the aircraft is used to evaluate groundspeed and the reflectivity of the runway surface to make estimates of the surface conditions, rough­ness …

Single-Degree-Of-Freedom Experiments Demonstrating Electromagnetic Formation Flying For Small Satellite Swarms Using Piecewise-Sinusoidal Controls, Ajin Sunny

Theses and Dissertations--Mechanical Engineering

This thesis presents a decentralized electromagnetic formation flying (EMFF) control method using frequency-multiplexed sinusoidal control signals. We demonstrate the EMFF control approach in open-loop and closed-loop control experiments using a single-degree-of-freedom testbed with an electromagnetic actuation system (EAS). The EAS sense the relative position and velocity between satellites and implement a frequency-multiplexed sinusoidal control signal. We use a laser-rangefinder device to capture the relative position and an ARM-based microcontroller to implement the closed-loop control algorithm. We custom-design and build the EAS that implements the formation control in one dimension. The experimental results in this thesis demonstrate the feasibility of the …
