Nonlinear pose control and estimation for space proximity operations: an approach based on dual quaternions

Autor: Salgueiro Filipe, Nuno Ricardo

The term proximity operations has been widely used in recent years to describe a wide range of space missions that require a spacecraft to remain close to another space object. Such missions include, for example, the inspection, health monitoring, su
