SVGS research to continue on the ISS until the launch in October

The new technology, developed by the Florida Institute of Technology and NASA, will be launched on the International Space Station later this month.

Hector Gutierrez, a mechanical engineering professor who works with Florida Tech’s Aerospace Systems Propulsion Laboratory (ASAP) and is affiliated with NASA Marshall Space Flight Center, said that the video guidance sensor (SVGS) on the smartphone was ISS at the launch of Crew-3. You will see it delivered to. Vehicle scheduled to be launched on October 30. Scientific operations using SVGS, a vision-based technology for navigation and proximity operations, will begin in mid-January and will run until 2022.

Check the sensor (SVGS). .30 launch. Scientific operations using SVGS, a vision-based technology for navigation and proximity operations, will begin in mid-January and will run until 2022.

An overview of SVGS technology with illuminated targets.

SVGS captures an image of a 4-point LED beacon and analyzes the pattern of illuminated dots on the captured image to determine the range and orientation of the target with respect to the camera frame. The system will be deployed and tested using NASA’s Astrobee free-flying robot.

Testing at the space station shows how to deploy SVGS as a software sensor using the hardware resources of the host robot platform (Astrobee in this case). SVGS location data is collected with Astrobee data for later comparison. The purpose of the comparison is to establish the accuracy of SVGS compared to the native positioning system used by Astrobee. Four SVGS Beacon Flight Units are used in five operations to demonstrate motion control and data capture.

One model of testing planned on the ISS, with lead and follower drones holding fixed positions at each waypoint. This operation is repeated at two different distances (0.75m and 1.5m) between the leader and the follower.

If successful, SVGS will enable future use of small satellites in the flight formation of multiple spacecraft, demonstrating potential benefits in close-range operations such as rendezvous, docking, and landing operations. The market for proximity-controlled sensors for space applications is currently open, and the ISS demonstration is an important milestone to help deploy SVGS for future opportunities.

The long-term vision includes evolving SVGS as a software sensor architecture that can be ported to robot platforms using host hardware resources (cameras and CPUs). This makes SVGS available to a wide range of user groups in applications such as multi-agent. Proximity operation by robot and automatic drone landing.

“SVGS technology holds great promise for a variety of proximity operations on robotic platforms. SVGS has a clear advantage over existing technology in short-range accuracy,” Gutierrez added. rice field.

Gutierrez has been working on SVGS development with the support of NASA Since 2017, in applications such as control of 3 degrees of freedom (a system that can control 3 position coordinates individually), control of electromagnetic formation operation, automatic drone landing in an environment where GPS is rejected, and now high altitude landing missions. It is being used.

Following the successful SPHERES-Slosh experiment in 2016, ASAP Labs has deployed a NASA-funded engineering experiment on the ISS for the second time in a few years. The direction of the ASAP Lab is shared between Gutierrez and Daniel Kirk’s Interim Dean. Faculty of Engineering.

“It’s an honor to be back on the ISS. SVGS is a great showcase of how NASA technology can be incubated and developed through collaboration with the university,” said Gutierrez.
