Spirent Federal Systems is collaborating with Xona Space Systems to develop simulation and test capabilities for Xona signals produced by smallsats operating in LEO. Xona is currently developing a smallsat constellation for a dedicated positioning, navigation, and timing (PNT) service.
Xona’s patent-pending approach using smallsats in LEO is intended to improve global PNT resilience and accuracy by both enhancing GNSS and operating as an independent system. Xona’s high-power signals use advanced signal structure and security techniques, improving jamming and spoofing resistance as well as multi-path mitigation.
The space and defense sectors also benefit from Spirent Federal’s expertise in generating high fidelity RF signals using quadrature (I/Q) data. Spirent test tools allow the full customization of I/Q data. Customers can generate unique I/Q data corresponding to experimental modulation schemes and use Spirent Federal’s signal generation capabilities to create the corresponding RF.
Such rapid prototyping allows for quick turnaround times and shorter iteration cycles. Alternatively, scenarios created using Spirent Federal’s proprietary SimGEN software can be saved as I/Q data which can be processed by software-implemented receivers.
“We do all we can to protect, toughen, and augment PNT and are eager to work with emerging companies like Xona who are developing a next-gen navigation and timing architecture,” said Jennifer Smith, Senior Director of Business Development at Spirent Federal. “Our simulators provide critical support to developers and integrators by enabling testing and validation before the product deploys.”
“Building a new generation of satellite navigation and timing services goes far beyond just the satellites,” said Brian Manning, CEO of Xona Space Systems. “It requires building an entire ecosystem from ground stations to chipset manufacturers to end users and systems integrators. Having reliable and trusted simulation capabilities is critical to support all of these areas, which is why we are thrilled to be working with Spirent to provide a robust solution to our partners.”
