Eliminating Errors: Protecting space travel from satellite collisions and debris

(L-R) Zero Error Systems’s co-founders Dr Wei Shu, Prof Joseph Chang, and Dr Kwen Siong Chong

According to the European Space Agency’s space debris office, there are hundreds of millions of objects floating in Earth’s orbit, ranging in size from 1 mm to 10 cm, caused by satellite collisions. These objects continue to create more debris and pose a serious threat to space missions.

Research scientist Dr. Wei Shu from Nanyang Technological University (NTU) realized that extending the lifespan of satellites is crucial to preventing future collisions and debris. In 2019, he partnered with his NTU professor, Joseph Chang, and Dr. Kwen Siong Chong to form Zero-Error Systems (ZES) to address this challenge.

ZES, based in Singapore, provides semiconductor integrated circuits and solutions to enhance radiation hardening and reduce soft errors in electronic circuits, ensuring the reliability of satellites in various environments.

The startup’s innovative approach, known as radiation hardening by design (RHBD), allows for the use of advanced commercial off-the-shelf (COTS) components in space applications, significantly lowering costs and improving performance.

ZES has successfully implemented its solutions in space missions, including partnering with OneWeb satellite in Europe. Beyond space, RHBD technology has potential applications in autonomous vehicles, particularly in ensuring high data integrity for level-4 and level-5 autonomous systems.

With successful funding rounds and a growing team, ZES aims to establish itself as a key player in the space industry, leveraging its cutting-edge solutions to tackle challenges related to space debris and satellite operations.

As the space industry evolves, ZES remains dedicated to innovation and establishing global standards for space applications. The startup’s mission is to safeguard vital space infrastructure and pave the way for humanity’s exploration of the cosmos.
