Spire Global, a global provider of space-based data, analytics and space services, successfully established a two-way optical link between two satellites in orbit. This achievement marks a major step toward enhancing the speed, reliability, and security of data transmissions for future missions.
The satellites, which launched in June 2023, are equipped with optical inter-satellite link (OISL) payloads. The payloads create lasers that send information back and forth between satellites, securely and almost instantaneously, while up to 5,000 kilometers apart. This technology has the ability to enhance applications such as weather forecasting, global communications, and remote sensing for navigation and environmental monitoring by increasing data speeds, enhancing security and reducing data latency.
