The Earth-Moon scenario will focus on evaluating and emulating different implementations of lunar rover control and data collection through different scenarios such as direct communication between Earth and a lunar lander, communications via a lunar relay satellit, and a Moon-orbiting (Low Lunar Orbit: LLO) satellite constellation connectivity to many rovers using 5G-SDR devices. Different mobile-communication equipment options will be evaluated for the lunar rovers (small VSATs, low-power omnidirectional antennas, satellite Internet-of-Things (IoT), etc.) by using SDR platforms. The encapsulation of Robot Operating System (ROS) commands in the MAC/Link/PHY layer will also be investigated. More advanced approaches such as reinforcement learning and deep learning techniques for remote control will be evaluated in a second stage as a means to provide safer, trustworthy and efficient remote control of the lunar rover.
The video illustrates a regenerative low-lunar orbit (LLO) sattelite that is oriting the lunar surface with an altitude of 100KM. On earth, we have a control mission room, so called concurrent design facility (CDF) where it host the 3GPP core network and and the teleoperator that monitor, and control the rover.Earth-Moon Communication and ROVER Teleoperation Via 5G-NR.
Demonstration for OAI Fall 2022 OpenAirInterface North American Workshop hosted by Qualcomm in San Diego on November 8th and 9th, 2022.
The objective of this demo is to evaluate the existing terrestrial technologies such as 4G/5G-NR for their suitability for Moon exploration scenarios. In the following architecture, we Emulate a low-lunar orbit (LLO) mission. In this mission we experiment two kind of delays:
- Earth-Moon communication delay that is impacting the SRI link [emulated using the kernel]
- Propagation delay on the nr-Uu interface [emulated using FPGA]
