What are the main challenges and opportunities of developing a lunar communication and navigation network?
As humanity prepares to return to the moon and establish a sustainable presence there, one of the key enabling technologies is a lunar communication and navigation network (LCNN). This network would provide reliable and secure data transmission, positioning, and timing services for lunar missions, both robotic and human. However, developing and deploying such a network poses several challenges and opportunities for spacecraft engineers, scientists, and entrepreneurs. In this article, we will explore some of the main aspects of designing, building, and operating a LCNN, and how it could benefit lunar exploration and development.
