On October 12, the GuardianSat initiative announced that it had won a grant from the National Science Foundation’s American Startup Fund to develop the company’s technology designed to protect satellites from collisions with space debris.
Delaware-based GuardianSat has been awarded a research contract worth approximately $273,000 for the first phase of small business technology transfer. Additionally, the company will receive technical support from Aerospace Corp. The Americas Seed Fund invests up to $200 million annually in promising startups.
The company developed a satellite debris avoidance system based on technology patented by one of its founders, Robert Briskman, one of the founders of Sirius XM satellite radio.
“Our proprietary solution is designed for satellites in high Earth orbit,” said Hugh Wyche, head of research at GuardianSat. “It will include a subsystem to detect orbital debris, track potential collision threats, and autonomously adjust the satellite’s course to prevent accidents.”
Sensors to detect objects
Viche said the debris detection technology, called the Autonomous Satellite Orbital Debris Avoidance System, includes satellite control systems, sensors and tracking systems, as well as interfaces that interact with the propulsion engine and communications subsystems on the satellite. It is also designed to help the satellite return to its home position after maneuvering to avoid debris and to share object data with other satellites to improve space awareness.
GuardianSat CEO Christopher Roe said the NSF grant “will allow us to advance the development of our space domain warning and avoidance systems.” “We are excited to take the next steps and continue to develop new, transformative solutions to keep the field open.”
Roe and Briskman founded GuardianSat in 2020.
Wyche said GuardianSat uses a “multispectral approach to detect orbital objects.” Multispectral sensors can distinguish different types of objects based on their spectral properties. “This capability is valuable for distinguishing between active satellites, inactive spacecraft, and space debris,” he explained.
Wyche added that the anti-debris system is a companion technology to GuardianSat’s “anti-satellite countermeasures system” currently under development. It uses microwaves and lidar (light detection and ranging) to detect and track approaching objects. Source
