Abstract
In interplanetary missions, the landing of space vehicles is typically accomplished using
parachutes. However, this simple method is not without its challenges, as these vehicles
are prone to parachute drifts that are difficult to predict, especially on planets with dense
atmospheres like Earth. As a result, significant attention has recently been given to the
development of active control systems for space vehicles, allowing for precise guidance, navigation,
and control over predetermined trajectories and enabling soft and accurate landings
on planetary surfaces.
The ability to follow a predetermined path and land softly and precisely using real-time
onboard control algorithms would greatly enhance the capabilities of vehicles for interplanetary
travel, while also increasing the re-usability of space vehicles. This not only benefits
interplanetary travel but also improves space payload delivery systems by reducing costs and
increasing efficiency.
To this end, this project aims to implement control algorithms on an Electric Ducted
Fan (EDF) powered model of a Vertical Take Off and Landing (VTOL) vehicle, enabling
it to follow a fixed trajectory. A small CanSat payload will be attached to the vehicle and
deployed at a specific altitude, simulating the tasks required of a full-scale vehicle.
By utilizing these advanced control systems, space vehicles can navigate more accurately
and efficiently, reducing the risks and costs associated with interplanetary travel. With a
focus on trajectory control and precision landing, this project aims to contribute to the ongoing
efforts to enhance space exploration and technology development.
