Meet L5-direct™

World’s first direct-to-L5, L1-independent GNSS receiver directly captures signals in the L5-band, delivering performance, deep urban accuracy, resilience against jamming and economic gain to users, defense agencies and OEMs 

GPS jamming threats in numbers

911 calls are made each day from mobile phones in the US

people could be affected by GPS jamming in the metropolitan area of Seoul

flights were reported to be affected by GPS interference in the Baltics region in 2024

FROM THE WSJ:

Poor Regulations are Jamming GPS Security 

“L5 operates on a different frequency and offers full redundancy. Its signal is more robust by a factor of 30. The enabling satellites, however, have been awaiting launch for over two years. Integrity monitoring of L5 also has been delayed for years.” 

~ Prof. Bradford Parkinson

L5-direct:
SPOOF-PROOF IN THE FIELD

Tests conducted near Haifa, Israel, compared the location accuracy of receivers in leading mobile devices. oneNav’s L5-direct receiver maintained correct location, while L1 GPS signals, affected by intentional signal interference, relocated the other devices to Beirut.

Why L5-direct?

ASAP

Engineered specifically for L5 signals, the Application Specific Array Processor (ASAP) is a “GPU for GNSS” that directly acquires L5 signals without sacrificing sensitivity or time to fix performance. This industry first was pioneered by oneNav and protected by a broad portfolio of patents.

Multi-constellation

Supports over 70 satellite signals from GPS, Galileo, QZSS, and BeiDou, with the ability to enable or disable select constellations.

100% independent from the legacy L1 signal

L5-direct is the only technology that unleashes the full power of the modern L5-band signals including strong signal transmission within a protected band.

Fast location acquisition without assistance in all environments

L5-direct delivers unparalleled reliability ensuring consistent and accurate positioning even in the most challenging conditions.

Single RF chain for optimal antenna placement

Simplify your design and enhance efficiency with a single RF chain. This approach conserves space, allows for optimal antenna placement, and reduces complexity, translating to smaller form factors and lower overall system costs.

Half the size, rBOM, and cost

This reduction is critical for applications with strict size and cost constraints, especially for wearables, IoT devices, and other compact electronics where space and budget are key considerations.

10x better tracking resolution

L5-direct signal half-chip spacing is 10x narrower than L1 signals, to discriminate direct from reflected signals in challenging environments.

Machine learning multipath rejection

Our solution employs advanced algorithms to analyze and classify signal patterns, distinguishing direct signals from multipath reflections. By training on vast datasets of signal behavior, our system effectively mitigates multipath errors.

More precise initial location acquisition without assistance

Achieve more precise initial location acquisition in standalone mode. L5-direct enables rapid and accurate positioning without relying on external assistance. This efficient solution provides immediate location data, saving time and resources.

ASAP processing power

Our innovative Application Specific Array Processor wakes up, performs an intensive parallel search, and then abruptly halts to conserve energy. This optimizes processing speed and minimizes power consumption. 

Low power L5 RF Analog

For applications requiring extended battery life, such as wearables, IoT devices, and asset trackers, our low power L5 RF Analog design ensures long operational periods without compromising performance, enabling continuous and reliable location tracking.

10% duty cycle in tough areas

Our intelligent power management system dynamically adjusts the receiver’s operation, reducing power consumption.

Enables always on location

Our system maintains continuous location awareness by intelligently balancing power consumption and performance, ensuring uninterrupted data availability.

Full immunity to widespread L1 jamming

Operating independently of L1, our receiver is unaffected by L1 jamming, which is a critical security feature. Our technology protects against signal disruption, ensuring accurate and trustworthy positioning in contested environments.

30x more resilience to in-band jamming

Anticipating future challenges, our technology provides 30x more resilience to in-band (L5) jamming. This enhanced protection against emerging L5 jamming techniques ensures robust and reliable performance, even as the threat landscape evolves.

7x smaller jamming radius of L5 vs L1 jammers

Gain a tactical advantage with this reduced L5 jamming footprint as it significantly enhances operational effectiveness in situations where signal interference is a factor.

NTN links and L1 signal proximity problem

The frequencies used by NTN systems to communicate with their ground stations or user devices are close to the 1575.42 MHz frequency used by GPS L1 signals. Strong L1 signals could interfere with the NTN’s ability to reliably send data to user devices (downlink) and receive data from user devices (uplink). Conversely, NTN transmissions could disrupt the reception of L1 signals, causing inaccuracies in GPS location data. 

Full coexistence with 3GPP NTN band N2555

L5-direct ensures seamless integration with emerging non-terrestrial networks. This capability allows our receiver to operate effectively in hybrid environments, combining satellite-based positioning with cellular connectivity for enhanced reliability and coverage.

Lifeline connectivity in remote areas

NTN coexistence means faster emergency response in remote locations. When seconds count, our technology ensures a rapid connection to emergency services potentially saving lives in areas where traditional networks are unavailable.

Markets we serve

Better resilience and low SWAP-C for all critical missions

Exact location accuracy while using ultra low power

All devices. All environments.
