Germany’s Space Startup Company unveils CubeSats for its revolutionary technology for flight formation 

Several satellites launch missions that sent hundreds of broadband satellites to Earth’s lower orbit never utilized a system for aligning the satellites. Most of the launch vehicles deployed their satellite shipments in a haphazard process, flooding outer space with all sorts of satellites and spacecraft. The lack of order in delivering the shipment leads to space debris’ build-up, a significant challenge in modern space explorations. Experts and space technologists continue to develop different solutions to the navigational problems caused by the accumulation of space junk. 

Recently, the International Space Station evaded a near-collision experience when the projectile of a spacecraft fragment passed a few kilometers from the station’s spacecraft dock. Many scientists and astronauts collaborated with space technologists and innovators to formulate strategies for eliminating fragments floating in outer space. In the first development phase, innovators came-up with unique navigation systems with pinpoint accuracy and precision to help spacecraft travel through the ever-floating space debris. The maritime technology is similar to the Global Positioning System or GPS, the technology for modern-day digital solutions. 

The Wurzburg Center for Telematics partnered with Smart Small Satellite Systems GmbH, a German startup, to developed and deploy the three-unit CubeSat known as NetSat. Recently, the partnership developed and inaugurated a mission to send the four-satellite NetSat to Earth’s lower orbit on September 28. The Russian Soyuz launch vehicle carried the NetSat satellite designed to demonstrate a revolutionary flight-formation technique. Developers of the system believe that the technology offers a solution to the on-going space projects that aim to remove space debris. 

Klaus Schilling, the director of robotics at the University of Wurzburg for Telematics, said that the four-satellite CubeSat aims to illustrate flight-formation using its current configuration in three-dimension. The technology opens up opportunities for innovative and scientific approaches that will propel better satellite architecture for upcoming launch missions for Earth Observation satellites and broadband satellites for telecommunications. The developers of NetSat anticipate that the mission will reveal strategies for avoiding collisions with space debris. Amidst the on-going COVID-19 global pandemic, the team adhered to the German government’s regulations to prevent the coronavirus spread. The builders of the NetSat CubeSat wore masks every time they were 1.5 meters from one another.

In summary, the NetSat CubeSats utilize the inter-satellite link technology to broadcast signals for navigation and information for satellite control. Each CubeSat incorporates an electric thruster; the whole satellite weighs approximately four kilograms. The NetSats use reaction wheels that point each thruster to the desired direction. During the launch mission, the CubeSat traveled in an orbital projectile alongside three broadband telecommunications satellites for Russia’s Gonets and several miniature satellites. Exolaunch coordinates the satellite shipment to the mission’s launch site, alongside integrating and inaugurating the satellites into orbit.
