successes is an initial prototype of the camera on a hardware platform that\u2019s ready for use in space: a so-called FPGA (Field Programmable Gate Array) System-on-Chip (SoC) specifically designed for the harsh operating conditions in space. Head of Research Group J\u00fcrgen Wassner and his team could draw on their extensive expertise in developing FPGA solutions for complex signal processing tasks such as the Powerline Train Backbone technology for the digital freight train.&nbsp;<\/p>\n\n\n\n<p>The first question to address was how to test the camera before it is launched into space. There aren\u2019t nearly enough real-life images from space to train the camera\u2019s AI models. And how could the team realistically simulate the movements of the target objects and the hunter satellite in their orbit around Earth in the lab?&nbsp;&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How the Visual Servoing Testbed works&nbsp;<\/h2>\n\n\n\n<p>The researchers went on to build a testbed tailored to addressing these challenges in a SERI-funded project.&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The testbed works with digitally generated visuals\u2014actual moving objects are not required.&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Artificially generated images closely simulate the situation in space,&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>and astro-dynamic modeling ensures that the objects in the generated images move exactly like their real counterparts in space.&nbsp;<\/li>\n<\/ul>\n\n\n\n<p>With this test environment, any volume of high-quality training data for the camera\u2019s AI models can be generated. But there\u2019s more: in a different operating mode, the camera itself can be tested in realistic conditions. To this end, the trained AI models are executed in a so-called camera-in-the-loop simulation on the FPGA SoC platform. The tests show how the entire camera system\u2014including the image sensor\u2014performs in real-time operation.&nbsp;<\/p>\n\n\n\n<div class=\"swiper__responsive-container \">\n\t<div

mechanical, or both?&nbsp;<\/h2>\n\n\n\n<p>The ESA\u2019s GRALS (Guidance Navigation and Control Rendezvous, Approach and Landing Simulator) test lab follows a different approach. There, the research focus is on robot-controlled satellite models (known as mockups) that simulate movement in space. Both in shape and appearance, the mockups should be as similar as possible to the real objects in space.&nbsp;<\/p>\n\n\n\n<p>It\u2019s unclear which approach will eventually prove fruitful. Quite possibly, both methods will be necessary to reliably test technologies for image-based navigation in space under lab conditions. The Foundation for the Promotion of the Lucerne School of Engineering and Architecture supports the activities of the researchers at the CC ISN. This funding allows them to contribute to the international discourse on the topic in a meaningful way.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The human eye as a model for an energy-efficient camera&nbsp;<\/h2>\n\n\n\n<p>Testing the camera is just one of the challenges the researchers are facing: the very limited energy budget aboard the hunter satellite is another. That is why the camera\u2019s AI models must learn to control their energy hunger.&nbsp;<\/p>\n\n\n\n<p>Here, the team of the CC ISN takes inspiration from the human visual system. In the human eye, signals from approximately 100 million photoreceptors are compressed onto approximately 1 million nerve fibers in the optic nerve and transported to the brain as electrochemical impulses. The brain then builds an image of the environment from these impulses.&nbsp;<\/p>\n\n\n\n<p>Thanks to the Adrian-Weiss Foundation\u2019s generous donation to the HSLU Foundation, the team is now ready to test a novel image sensor modeled after human eyesight. Combining it with spiking neural networks, which are a type of artificial neural network, the researchers hope to further reduce the energy consumption of the space camera.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The space camera is ready for the next level&nbsp;<\/h2>\n\n\n\n<p>The plan is to have a visual test environment and a prototype of the space camera by the time the current project wraps up. But the team\u2019s work won\u2019t be finished\u2014far from it. The researchers will progress to the next stage, aiming to refine the camera to a higher TRL (Technology Readiness Level) through a requirements-based development process.&nbsp;<\/p>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary><strong>Technology Readiness Level (TRL)<\/strong><\/summary>\n<p><em>Originally conceived at NASA in 1974, the TRL system is now a nine-level scale estimating the maturity (technology readiness) of a technology.
