Fiducial markers play a key role in enhancing the accuracy and reliability of space-based robotics and vision systems. SQUID3's fiducial markers are designed with materials that withstand the harshest space environments, providing long-lasting optical contrasts throughout long-duration missions. Our space-grade adhesive backing ensure reliable and secure placement on a variety of spacecraft and robotic surfaces. This product can be coated with SiO₂ to mitigate atomic oxygen (AO) erosion and electrically conductive Indium Tin Oxide (ITO) to control spacecraft surface charging.
