Xona Space Systems to launch six satellites for commercial GPS alternative

Commercial GPS Alternative Launching

Xona Space Systems is preparing to launch six satellites this month, marking the debut of its commercial precision navigation and timing service. This initiative aims to offer an alternative to existing government-operated GPS and other global navigation satellite systems.

Addressing GPS Limitations

The company was founded in 2019 by engineers from Stanford University, including Tyler Reid, whose PhD research focused on low-Earth orbit satellites for navigation. The founders identified limitations in current GPS systems, such as susceptibility to jamming and insufficient precision for advanced applications like autonomous vehicles and agricultural robots.

Xona's CEO, Brian Manning, noted that while GPS is a free service, the market for hardware that utilizes navigation signals is substantial and seeks better performance.

Technical Innovations

Xona developed a unique architecture that allows its satellites to maintain precise timing without expensive onboard atomic clocks, by leveraging their proximity to Earth and communication with ground-based sources. Another technical challenge solved was ensuring compatibility with existing GPS receivers through a relatively simple software modification, facilitating market access and regulatory approval.

Satellite Deployment

A SpaceX rocket is scheduled to launch the six satellites. Four of these satellites are based on a prototype launched last year, built on a satellite platform from Aerospace Labs. The remaining two satellites are also part of this initial deployment.
