SpaceX, one of the world's top aerospace manufacturers and space transportation companies, has recently revealed its foray into the sale of satellite laser technology, bringing its advanced data transmission capabilities to firms worldwide.
Reuters reports that Gwynne Shotwell, President of SpaceX, unveiled the company's venture into satellite laser sales at the Satellite Show conference held in Washington.
Shotwell disclosed that SpaceX is extending its groundbreaking technology, utilized in the Starlink satellite constellation, to other satellite companies.
The technology leverages inter-satellite laser links to achieve data transmission at the speed of light, facilitating enhanced internet coverage across the globe with reduced reliance on ground stations.

LOS ANGELES, CALIFORNIA - MARCH 18: People take photos of a SpaceX Falcon 9 rocket carrying a payload of 22 Starlink internet satellites into space after launching from Vandenberg Space Force Base on March 18, 2024 as seen from Los Angeles, California. The launch was visible across much of Southern California and occurred four days after the third test flight of the Starship rocket which launched from Texas.
SpaceX's Satellite Laser Tech
Starlink, the satellite internet constellation operated by SpaceX, introduced laser-based communication capabilities as early as 2021. These Optical Intersatellite Links (ISLs) enable direct communication between satellites within the constellation, bypassing the need for constant communication with ground stations. This innovation significantly improves internet speeds for users and minimizes latency in data transmission.
With over 8,000 lasers within the Starlink constellation, each capable of achieving data transfer speeds of up to 100 Gbps, SpaceX aims to set new standards in satellite communication technology. Travis Brashears, a SpaceX engineer, revealed that the laser system can deliver an astounding 42 petabytes of data daily to Starlink customers worldwide.
Moreover, the laser system's reliability is noteworthy, boasting a remarkable link uptime exceeding 99%, despite the inherent challenges of maintaining connections across thousands of satellites orbiting the Earth. This reliability is crucial for ensuring uninterrupted data transmission and seamless internet connectivity for end-users.
Brashears further showcased the laser system's capabilities, citing instances of long-distance connections between satellites spanning thousands of miles. Notably, the system successfully maintained a connection across a distance of 5,400 kilometers, demonstrating its robustness and adaptability in various operational scenarios.
What's Next?
The potential applications of SpaceX's satellite laser technology extend beyond internet connectivity. By offering high-speed data transmission capabilities, the technology holds promise for diverse industries, including telecommunications, navigation, and remote sensing.
As SpaceX prepares to launch its Polaris Dawn mission later this summer, featuring the deployment of satellite lasers onboard a Dragon space capsule, the company's vision for the future of satellite communication appears brighter than ever.
"We generally don't sell components, so this is a little bit of a new thing for us," Shotwell told Reuters. She also confirmed that SpaceX was already in talks with potential customers.
