oneNav, Inc.

oneNav, Inc., a pioneer in semiconductor technology, is making significant strides in the field of GNSS (Global Navigation Satellite System) receivers, focusing particularly on its L5-direct receiver technology. The company has carved a niche for itself by developing the world's first L5-only and L1-independent GNSS receiver, a revolutionary step in navigation technology. This advancement offers enhanced performance, accuracy in urban settings, resilience against signal jamming, and economic benefits, making it highly valuable for defense agencies, OEMs, and end-users. The L5-direct receiver, engineered by oneNav, has been specifically optimized for L5-band signals. Employing an Application Specific Array Processor (ASAP), this receiver is akin to a GPU for GNSS, directly acquiring L5 signals without compromising sensitivity or time for location fixing. By supporting over 70 satellite signals from systems such as GPS, Galileo, QZSS, and BeiDou, and operating independently from the outdated L1 signals, oneNav's technology showcases its capability to deliver reliable and precise positioning across various conditions. A notable feature of oneNav's technology is its compact and cost-effective design. With a single RF chain enabling optimal antenna placement, the receiver is ideally suited for compact and budget-sensitive applications like wearables and IoT devices. The signal half-chip spacing, ten times narrower than traditional methods, significantly improves signal discrimination, and the use of machine learning for multipath rejection enhances overall accuracy. Moreover, oneNav's solutions are tailored to withstand GNSS disruptions, ensuring continuous and precise positioning. The L5-direct technology provides full immunity to L1 jamming, a vital security feature, and is thirty times more resilient to in-band L5 jamming. By allowing seamless coexistence with emerging networks, including NTN band N2555, oneNav enhances connectivity and supports faster emergency responses in remote areas. Choosing oneNav technology translates to advanced GNSS capabilities with reduced size and cost requirements, empowering OEMs and integrators to optimize device performance without sacrificing reliability.

L5-Direct GNSS Receiver

The L5-Direct GNSS Receiver by oneNav is a pioneering solution designed to acquire and process L5-band signals independently. This advanced receiver utilizes a unique Application Specific Array Processor (ASAP) to directly acquire L5 signals, ensuring high sensitivity and rapid location fixing. This innovation allows the receiver to function effectively without relying on the older L1 signals, providing a robust alternative in urban settings where signal interference can be a significant issue. The technology supports a multitude of satellite signals, including those from GPS, Galileo, QZSS, and BeiDou, enabling it to adapt to various constellations. Its design optimizes space and power through a single RF chain, reducing the need for complex dual-band systems. This results in a smaller footprint and lower costs, making it ideal for compact electronic devices such as wearables or IoT gadgets. One of the standout features of this technology is its ability to manage multipath errors using machine learning algorithms, which effectively discriminate between direct signals and reflections. The receiver's resilience against GPS spoofing and jamming enhances security and trustworthiness, critical in areas of contested or compromised signals. By integrating seamlessly with non-terrestrial networks, the L5-Direct GNSS Receiver ensures reliable connectivity and positioning in diverse environmental conditions. Moreover, oneNav's receiver is built for endurance and efficiency, with a design that allows for continuous, low-power tracking—a feature especially beneficial for battery-operated applications. The overall architecture demonstrates significant advancements in both GNSS receiver technology and the broader field of navigation systems, offering unparalleled performance, precision, and reliability in the GNSS domain.
