A Historic Experiment is Underway
The U.S. Space Force, in collaboration with Lockheed Martin, is gearing up for an unprecedented laser communications trial utilizing a Global Positioning System (GPS) satellite. If this initiative proves successful, it could revolutionize the accuracy and functionality of navigation systems that billions rely on daily.
Testing the Waters from Space
Scheduled to occur on the GPS III SV-10 satellite, which was constructed by Lockheed Martin and remains ready in storage, this demonstration aims to innovate communication technology from an orbit nearly 12,000 miles above the Earth. An optical communications terminal, crafted by German aerospace company Tesat-Spacecom and its American branch, will facilitate this groundbreaking test by sending data from the satellite to Earth-based stations.
A New Age for GPS Technology
According to a Lockheed Martin executive, this experiment is a vital move towards updating the GPS framework, gleaning insights for the future GPS IIIF constellation upgrades. The SCOT80 terminal, already utilized in various low Earth orbit satellites, showcases the potential of space-based laser communications.
Enhancing Communication Efficiency
A commander from the Space Force elaborated on the transformative potential of this technology, emphasizing the goal to authenticate laser communications at GPS altitudes. The long-range plan includes creating optical crosslinks, contributing to faster data transmission and improved security. With its origins in military applications, the GPS system is now pivotal for everyday tasks, and this new technology could reshape how we interact with satellite communications.
