Formation estimation methodologies for distributed spacecraft systems are formulated and analyzed. A generic form of the formation estimation problem is described by defining a common hardware configuration, observation graph, and feasible estimation topologies.
Spaceborne optical interferometry has been identified as a critical technology for many of NASA's 21st century science visions.

In this paper we present a solution to the formation initialization problem for N distributed spacecraft located in deep space. Our solution to the FI problem is based on a three-stage sky search procedure that reduces the FI problem for N spacecraft to the simpler problem of initializing a set of sub-formations. We demonstrate our FI algorithm in simulation using NASA's five spacecraft Terrestrial Planet Finder mission as an example.

This paper presents an adaptive control system for coordination and control of a fleet of micro-spacecraft moving in formation.
The Leader/Follower (L/F) architecture is currently being considered as a method for controlling formations consisting of spacecraft, robots, UAVs and other autonomous vehicles.
Presentation to POIWG meeting at MSFC to discuss planned operations for upcoming FFL-01 mission on SpaceX-5. Will show hardware suite used, on-orbit operations, training strategy, and data handling architecture.
