Abstract

The main objective of this research is to develop and implement algorithms for autonomous formation flight in future INTA missions (ANSER-AT and Q-ANSER), utilising the aerodynamic forces of lift and drag in low Earth orbit. This is particularly interesting for groups of small platforms, as they can carry out formation flight control in different orbital configurations without consuming energy and without the need for a propulsion system. These future missions aim to fulfil Earth observation objectives: ANSER-AT (scheduled for launch in 2027) is a mission dedicated to studying the chemical composition of the Earth’s atmosphere, and Q-ANSER (currently in the pre-design phase) will focus on quantum key distribution, with the key feature that the satellites will have the capability to perform manoeuvres autonomously in orbit.
