To mitigate these challenges, the satellites are often designed with redundant systems and excess fuel. However, this increases their complexity, weight, and cost.
The development of on-orbit servicing technologies, such as robotic repair and refueling, offers a potential solution to extend satellites’ lifespans and reduce the need for frequent launches.
“The military regularly fixes aircraft, tanks, ships, and trucks that break. We upgrade aircraft and ships with the latest radars, computers, and engines,” said Glen Henshaw, Ph.D., NRL senior scientist for Robotics and Autonomous Systems.
“Satellites are the only expensive equipment we buy that can’t be repaired or upgraded once they are in the field, and this costs the taxpayer money. RSGS is intended to change this situation; we intend to demonstrate that we can upgrade and repair these valuable assets using robots,” Henshaw stated.
