The ESA Lunar Lander mission is tasked with landing safely on the lunar surface near the lunar South Pole. The mission aims to demonstrate the capability of performing soft precision landings and autonomous hazard detection and avoidance (HDA) during the descent and landing phase. The final portion of the descent and landing phase is the approach phase, during which time the spacecraft is steered to the final landing site via the GNC, while providing a vehicle attitude for sensor observations of the landing site and surrounding terrain. An HDA subsystem is active during this phase and uses data from a camera and a Lidar to assess the safeness of the terrain around the landing site and select a safe landing site for GNC targeting. The GNC drives autonomously the vehicle to perform a soft landing at the landing site, performing trajectory diverts when new landing sites are selected by HDA. This paper describes the GNC concept and architecture for the approach phase of the descent and landing portion of the Lunar Lander mission, with emphasis on the details on the guidance and control (G&C) algorithms and the achieved G&C performances. The performance of the G&C subsystem is demonstrated through Monte Carlo simulation campaigns on a functional engineering simulator, with both the GNC and HDA algorithms active. |
