Attitude Synchronization Control in Satellite Formation Flying in the Presence of States Measurement Errors

This paper presents a novel attitude synchronization framework for tracking control of multiple identical/heterogeneous satellites in formation flying with connected communication graph. The main contribution of the paper is considering sensors' measurement error to derive control gains. Moreover, the proposed strategy need no angular velocity communication. Nevertheless, the tracking synchroni...

Possible Orbit Scenarios for an InSAR Formation Flying Microsatellite Mission

Multistatic interferometric synthetic aperture radar (InSAR) is a promising future payload for a small satellite constellation, providing a low-cost means of augmenting proven “large” SAR mission technology. The Space Flight Laboratory at the University of Toronto Institute for Aerospace Studies is currently designing CanX-4 and CanX-5, a pair of formation-flying nanosatellites slated for launc...

Attitude Determination for Small Satellites with Modest Pointing Constraints

This monograph reports on the development of the attitude determination backbone of the Ionospheric Observation Nanosatellite Formation (ION-F). Three spacecraft with similarly modest pointing constraints comprise the ION-F constellation. Pointing requirements for the constellation are dictated by the formation flying mission objective and communication demands. To satisfy pointing requirements...
