Using a co-located GNSS radio occultation payload for microwave radiometer calibration
… (RO) instrument with Global Navigation Satellite Systems (GNSS). The radiometer and RO receiver periodically observe the same volume of atmosphere near the earth's limb, allowing for overlapping, or collocated, measurements that can be used to calibrate the radiometer. This method leverages the …

Design principles for the development of space technology maturation laboratories aboard the International Space Station
… of laboratories which utilize the International Space Station (ISS) to demonstrate the maturation of space technologies. The principles are derived from the lessons learned from more than two decades of space technology research at the MIT Space Systems Laboratory and the existence of unique …

Flight hardware development for a space-based robotic assembly and servicing testbed
Robotic assembly and servicing missions in space are becoming increasingly attractive for their potential to expand space capabilities and save money. Future missions may construct large systems on-orbit, service existing space assets, or remove retired satellites from valuable locations in the …

Design and utility assessment of attitude control systems for EVA task performance
… servicing and assembly missions could benet from spacecraft systems capable of maintaining pointing stability during critical operations. The addition of single-gimbal control moment gyroscopes (CMGs) to the attitude control system of these spacecraft could substantially improve the stability and …

Development and analysis of a small satellite attitude determination and control system testbed
Attitude Determination and Control Systems (ADCS) are critical to the operation of satellites that require attitude knowledge and/or attitude control to achieve mission success. Furthermore, ADCS systems only operate as designed in the reduced friction, micro-gravity environment of space. …

Dynamic and thermal control of an electromagnetic formation flight testbed
Formation flight of multiple spacecraft is an emerging method for completing complex space missions in an efficient manner. A limitation found in maintaining such formations is the need for precise control at all times. Using traditional thruster propulsion systems can be costly and life-limiting …

Improving attitude determination and control of resource-constrained CubeSats using unscented Kalman filtering
… the art in attitude estimation on previous MIT Space Systems Laboratory CubeSats by at least two orders of magnitude from about 1-5* attitude knowledge error down to 0.050 or better. This improvement benefits applications that require precise pointing, such as imaging and active tracking of …

Design and implementation of the state estimator for trajectory following of an electromagnetic formation flight testbed
… an attractive concept for achieving complicated space missions that are di±cult or impossible with a single monolithic satellite. Since traditional thrusters require propellant consumption for maintaining the formation of multiple satellites, one concern is the way of more efficiently generating …

Development of an incremental and iterative risk reduction facility for robotic servicing and assembly missions
… to enable life extension programs for existing spacecraft while also enabling much larger and more complex satellites to be developed through on-orbit construction. Unfortunately, many of the new and innovative technologies required for RSA to be economically and technically feasible are still …
