This survey deals with the problem of group motion spacecraft, which is rapidly developing and relevant for many applications, in terms onboard control algorithms to ensure fulfillment a given mission. The paper provides comprehensive overview spacecraft formation flight control. bibliography divided into three main sections: multiple-input–multiple-output approach, treated as single entity mul...

Satellites in a formation might need to maneuver to avoid potential collisions that may occur when foreign objects enter the formation, or when a satellite within the formation drifts into the path of another. In either case we seek to determine the probability of a future collision based on current state knowledge and the uncertain dynamic environment, and further to determine a control strate...

Ground-support based satellite health monitoring and fault diagnosis practices involve around-theclock limit-checking and trend analysis on large amount of telemetry data. They do not scale well for future multi-platform space missions due to the size of the telemetry data and an increasing need to make the long-duration missions costeffective by limiting the operations team personnel. To utili...

Agent teaming and autonomy are foundational themes in multi-agent systems. Agents may work as singletons or they may work in environments where other agents exist. In multi-agent systems, agents may form teams by sharing common goals with other agents. Cooperation is essential for any collaborative, group activity. Beyond coordination and judicious role assignment, cooperation enables members o...

Interferometry in space has marked advantages: long integration times and observation in spectral bands where the atmosphere is opaque. When installed on separate spacecraft, it also has extended and flexible baselines for better filling of the uv plane. Intensity interferometry has an additional advantage, being insensitive to telescope and path errors, but is unfortunately much less light-sen...

Electromagnetic formation flight (EMFF) is an enabling technology for a number of spacecraft mission architectures. The RINGS program will be the first time EMFF is demonstrated in a microgravity environment. Nonlinearities due to magnetic field interactions preclude linear feedback controllers from being used to control the RINGS system. Approximate dynamic programming is explored in this pape...

This paper presents the management of UAV formation flight with respect to varying levels of communication among UAVs. Inter-vehicle communication in the formation is a critical issue because each UAV needs the information on other vehicles for formation. However, since communication is not perfect in reality, the formation performance under communication failure has to be analyzed. This study ...

For centuries, mankind has been fascinated by V-formation flight in birds. Back in AD 79, Pliny the Elder noted that flocks of geese flew ‘like fast galleys, cleaving the air more easily than if they drove at it with a straight front’, and since then, numerous ideas have been proposed to explain the function of the V-shaped flocks that are a such a familiar sight. Many of these explanations oft...

This paper examines the interaction between Semiotic choices and the presentation and solution of a family of contemporary mathematical problems centred around the so-called 'stable marriage problem'. I investigate how a socially restrictive choice of signs impacts mathematical production both in terms of problem formation and of solutions. I further note how the choice of gendered language end...
