Abstract
Planetary Transportation Systems GmbH (PTS) is developing a second iteration of their lunar lander called Autonomous Landing and Navigation Module (ALINA)-2. With a wet mass of approximately 4 tonnes, ALINA-2 will be capable of transporting 300 kg of commercial payloads from Geostationary Transfer Orbit (GTO) to the lunar surface. Several key enabling technologies are employed on ALINA-2. These include a 4 kN propulsion system which provides the necessary thrust for the Power Descent Maneuver (PDM) to the lunar surface and a total ?v of 3700 m/s for all maneuvers. The motors can be pulsed to vary the thrust level and improve the controllability of the lander. During the PDM, ALINA-2's Guidance, Navigation and Control (GNC) utilizes a combination of radar, laser altimeters, and crater navigation technology to facilitate a soft and accurate landing. Carbon fibre reinforced polymer is used strategically to lower the weight of ALINA-2's main structure and landing legs, while phase changing materials are employed on units with high heat loads. In addition to hosting a wide variety of commercial payloads, the lander can deploy two rovers equipped with Long Term Evolution (LTE) transceivers. ALINA-2 will use an LTE base station to communicate with the rovers, allowing them to stream High Definition (HD) video back to Earth.
