Unlike current mobile GNSS solutions, which depend on L1 satellite signals that were developed in the 1970s, says the company, its pure L5 solution is built from the ground up to fully leverage modernized L5 signals from the GPS, Galileo, Beidou and QZSS navigation satellite constellations. Such L5 signaling enables higher accuracy, broadcasts in a protected frequency band, has modern error correction, and is transmitted at higher power.

“Navigation satellite constellations are getting a major upgrade—L5 signaling,” says Steve Poizner, co-founder and CEO of oneNav. “oneNav has built the first pure L5 mobile receiver to leverage these modernized signals, and we will deliver our solution in a flexible licensing model, as a scalable and customizable IP core.”

Paul McBurney, oneNav’s co-founder and CTO adds, “Pure L5 is a more cost, size and power efficient method to enable the benefits of modernized signals compared to current hybrid solutions.”

Legacy L1 systems, says the company, can have significant accuracy deficiencies, especially in dense urban areas, placing users on the wrong side of the street or on the wrong block. L1 signals are also susceptible to jamming. Unlike current L1+L5 hybrid solutions that must first acquire on L1, the company’s Pure L5 solution both acquires and tracks on the new L5 signals, without L1 aiding, thereby taking full advantage of L5 benefits.

Eliminating the need for L1 circuitry cuts GNSS RF size, power and cost in half, says the company. The company’s Pure L5 solution also uses AI to deliver much higher accuracy, even in challenging areas such as urban canyons.

The Pure L5 solution is offered as being ideal for highly space constrained devices such as smartphones, wearables, and IOT tracking modules. The solution is delivered in a semiconductor IP license package that includes RTL, software and reference designs that can be integrated into a system on a chip (SOC) or built as a discrete chip.

Common use cases for Pure L5 include the following:

  • Rideshare: Today’s mobile positioning technologies often place users on the wrong side of the street, or on the wrong block, making rideshare services very difficult to use. oneNav enables riders to more effectively match up with their drivers in downtown areas and other heavily blocked environments.
  • Smartphone Navigation: It is sometimes difficult to establish your exact location, or to determine which way to turn when using a mobile navigation application in a dense urban area. oneNav’s high availability and precise accuracy enables reliable turn-by-turn directions.
  • Emergency Calls: First responders need to accurately pinpoint the location of accidents in order to get to the right place quickly. oneNav’s reliable positioning and high accuracy get the right location information to ambulances, fire and police, enhancing public safety.
  • Asset Tracking: COVID-19 has increased the need for supply-chain assets to be transported and tracked with precision. oneNav enables accurate position reporting for asset tracking and other IOT applications.

Along with the Pure L5 announcement, the company annunced that it had closed a $21 million Series B funding round, led by GV, with participation from Norwest Venture Partners and GSR Ventures, bringing the total funding the company has received to $33 million.

Karim Faris, GV General Partner says, “The mobile device industry – from phones to wearables – has made tremendous progress over the last twenty years. What’s surprising is that location-based services continue to have a significant margin of error, which can make all the difference when locating a rideshare passenger or pinpointing an emergency situation. With oneNav’s Pure L5 Mobile GNSS receiver, OEMs and application service companies will have the opportunity to provide their customers with state-of-the-art location-based services, driving competitive advantage.”

The company also announced that it has signed a strategic partnership agreement with In-Q-Tel Inc., providing U.S. intelligence and defense agencies with a first-of-a-kind GNSS technology solution. For more, see the Pure L5 white paper.
