Geolocation companies consolidate as NextNav acquires Nestwave

NextNav Inc., a GPS and 3D geolocation company, has acquired Nestwave SAS, a privately held company specializing in low-power geolocation.

The acquisition was completed Oct. 31 for $18 million.

NextNav is based in McLean, Virginia, and Nestwave is located in based in Neuilly-sur-Seine, France. Nestwave provides advanced geolocation solutions to internet of things (I0T) modem and digital signal processor vendors and end IoT users.

Nestwave will adopt NextNav’s name and be integrated into existing TerraPoiNT engineering and technology efforts, with all Nestwave employees remaining with the company. Nestwave CEO Ambroise Popper will become NextNav’s vice president and general manager in France and is joining NextNav’s executive leadership team, while Nestwave CTO and Founder Rabih Chrabieh will serve as vice president of engineering.

The combination of NextNav’s technology with Nestwave’s LTE/5G capabilities will allow NextNav to intelligently combine signals from existing terrestrial LTE/5G networks with its own highly synchronized TerraPoiNT system to deliver near nationwide resilient 3D position, navigation and timing (PNT) capabilities that contribute to dramatically lower deployment costs.

The company serves markets including timing for critical infrastructure, aviation, automotive, IoT and other mass market applications sooner.

“The acquisition of Nestwave presents a unique opportunity for NextNav to optimize further the use of its existing spectrum bandwidth, while contributing to a drastic decrease of our TerraPoiNT system’s future capital and operating expenditures,” said Ganesh Pattabiraman, NextNav co-founder and CEO.

“By leveraging Nestwave’s unique technology and ambient LTE/5G waveform, NextNav can gain significant spectral efficiency, accelerate the availability of resilient PNT and release the underlying spectrum’s capacity for additional data-oriented services. An LTE/5G waveform also enables broader penetration of NextNav’s applications and technology across the handset and device ecosystem for all of its products and target markets,” Pattabiraman said.

Pattabiraman continued, “Nestwave brings not only a physical presence in Europe, but also a team of professionals who have established strong relationships with European Union representatives that will be beneficial as we continue active conversations with government officials in the United States, Europe and globally over GPS/GNSS resilience.

“The transaction is not expected to materially increase the company’s operational cash burn, and the lowered capital requirements will enable us to quickly scale our GPS resiliency capabilities in both the United States and global markets sooner than previously anticipated.”

NextNav posted a pre-recorded conference call to discuss the acquisition.

NextNav showcases APNT backup to GNSS at European JRC trial

NextNav participated in the European Commission’s Joint Research Centre (JRC) alternative positioning, navigation and timing (APNT) evaluation in Ispra, Italy. At the trial, NextNav showcased an alternative PNT backup to GNSS, TerraPoiNT.

According to the JRC, the trial is analyzing the technologies “which could deliver positioning, and/or timing information, independently from GNSS, to be effective backup in the event of GNSS disruption, and if possible to be able to provide PNT in the environments where GNSS cannot be delivered.”

The test furthers the European Union’s creation of a backup to GNSS and is intended to assess which technologies could strengthen and expand the European PNT capacity.

PNT services are critical for the global economy, with studies estimating a contribution to the European GDP of approximately 10%. Today, GNSS services are the backbone of PNT, with an increasing role in new services and technologies, including car-sharing, autonomous vehicles, ship and aircraft navigation, smart logistics and precision agriculture.

It’s About Time

The timing capabilities of PNT are heavily utilized today by critical infrastructure, which is strategic from a commercial and societal perspective, including telecom, energy, finance and transportation. Published studies estimated economic losses of around 1 billion EUR per day if GNSS were unavailable.

NextNav’s TerraPoiNT trial focused on measuring the precision of timing delivery across alternate timing sources to better understand performance in GNSS-free environments — including instances of outages, spoofing and jamming. As a part of the trial, NextNav also demonstrated its capabilities in providing both indoor and outdoor z-axis vertical location.

TerraPoiNT is a system for assured PNT that uses terrestrial transmitters deployed around a service area to triangulate the location of a device. Unlike national space-based systems, the proximity of NextNav’s transmitters makes the signal strength 100,000 times that of GPS.

“The trials are part of the global trend to develop a resilience layer to space-based GPS/GNSS systems that is more secure and available,” said Ganesh Pattabiraman, NextNav CEO. “We are redefining the capabilities of APNT technologies and look forward to working with the European Commission on furthering these initiatives to build a GNSS backup layer that can deliver highly precise PNT across use-cases.”

Trials for U.S., Europe

The U.S. and countries across Europe continue to invest in both understanding and taking steps towards creating a resilient PNT layer in each nation. Participation in the JRC trial builds upon the recent evaluation of APNT technologies in the United States, including a 2021 U.S. Department of Transportation report, where TerraPoiNT was found to be the best performing APNT solution across use cases.

Further, NextNav recently created an APNT testbed in the San Francisco Bay area that was developed as part of a U.S. Department of Homeland Security demonstration used to evaluate the precision and resilience of NextNav’s TerraPoiNT network.

The JRC is expected to report results from the evaluation this spring.

NextNav, Satelles collaborate on Bay Area alternative PNT testbed

Technology evaluation capabilities inaugurated in demonstration for U.S. Department of Homeland Seurity

NextNav and Satelles Inc. have partnered on an alternative positioning, navigation and timing (PNT) testbed in the San Francisco Bay area.

Designed and managed by NextNav with a timing source from Satelles, the testbed creates scenarios and conditions to rigorously test the precision and resilience of alternative PNT solutions, allowing technologies to be evaluated in the absence of signals from GPS and other GNSS.

NextNav used the testbed to demonstrate the precision and resilience of the company’s TerraPoiNT network in a GPS-denied environment using STL from Satelles as its absolute timing source. This demonstration for the U.S. Department of Homeland Security (DHS) showcased the timing accuracy and resilience of TerraPoiNT, which delivered timing synchronization better than 50 nanoseconds in urban and semi-urban settings.

As a source of GPS/GNSS-independent time that the U.S. National Institute of Standards and Technology (NIST) determined is highly consistent with Coordinated Universal Time (UTC) — including in deep indoor environments — STL provided the timing signal for the demo instead of GPS.

The advent of the alternative PNT testbed is timely given the recent publication of “Understanding Vulnerabilities of Positioning, Navigation, and Timing” by the Cybersecurity and Infrastructure Security Agency (part of DHS). This important CISA publication urges owners and operators of critical infrastructure to adopt the responsible use of PNT as defined in Executive Order 13905. The new testbed will be used to demonstrate applications for emergency services, telecommunications, financial markets, the electrical grid, and other critical infrastructure sectors.

“Demonstrating the accuracy and resilience of alternative PNT solutions is integral in validating the capabilities of alternative PNT solutions and, ultimately, increasing adoption across use cases and applications,” said Ashu Pande, TerraPoiNT VP at NextNav. “With the development of this testbed, we can emulate real world deployment scenarios and can more effectively instill confidence across the PNT industry in the viability of alternate PNT solutions.”

“The development of this testbed will enable the rigorous, transparent, and replicable testing of alternative PNT solutions,” said Christina Riley, VP of Commercial PNT at Satelles. “We’re excited to be integrated as the GNSS-independent timing reference for this alternative PNT testbed and are looking forward to continuing our collaborative work to build stronger PNT solutions to augment GPS globally.”

The U.S. Department of Transportation categorized TerraPoiNT from NextNav and STL from Satelles as the top-ranked PNT systems in its technology demonstration report released in January. The testbed collaboration between these complementary alternative PNT service providers underscores the companies’ commitment to promoting the adoption of multiple technologies that complement and augment GPS/GNSS to protect the operations of critical infrastructure.

NextNav demos GPS-free PNT network for critical infrastructure

The trial for the U.S. Department of Homeland Security showcases the precise, resilient timing capabilities of NextNav’s TerraPoiNT service in the event GPS is unavailable.

NextNav has successfully demonstrated the timing precision and resilience of its terrestrial positioning, navigation and timing (PNT) system, TerraPoiNT, in a recent evaluation by the Science and Technology Directorate of the Department of Homeland Security (DHS S&T).

The trial tested the timing redundancy of the TerraPoiNT system in a number of scenarios, including instances of GPS outages, spoofing and jamming. It validates TerraPoiNT’s capabilities as a terrestrial, GPS-free network capable of powering critical national infrastructure in the event of GPS failure.

During a simulated 72-hour GPS outage, the TerraPoiNT service was able to deliver a timing accuracy better than 50 nanosecond in urban and semi-urban environments, successfully meeting timing requirements for various applications including 5G networks, the synchronization of the power grid, and more.

In addition, TerraPoiNT provided precise timing and redundancy utilizing two alternate absolute timing sources — atomic clock (Cesium/Rb) and LEO satellite (Satelles).

“GPS is critical infrastructure, but it has its limitations,” said Ganesh Pattabiraman, co-founder and CEO of NextNav. “In working with DHS S&T, we’ve validated that TerraPoiNT can serve as an important backup to GPS and ensure the resilience and continuity of our nation’s most critical systems, including next-generation telecommunications networks, financial services, and power grids.”

Satelles STL

STL from Satelles was one of two alternate absolute timing sources for the trial. Available today on a global basis, STL is a service that provides alternative PNT independent of GPS, supporting PNT-reliant applications such as 5G communications networks, high-frequency trading in financial markets, and electrical grids throughout the United States and around the world.

“Satelles applauds NextNav for conducting a successful field demonstration of its resilient PNT service, and we were delighted to have played an instrumental part in the exhibition,” said Christina Riley, vice president of Commercial PNT.

NextNav’s selection of STL to help demonstrate their own technology’s operation in the absence of GPS was a natural fit. That’s because earlier this year the U.S. National Institute of Standards and Technology (NIST) confirmed STL as an accurate and reliable source for the wide-area delivery of Coordinated Universal Time independent of GPS/GNSS.

Previous TerraPoiNT evaluations

The successful trial builds on recent evaluations of TerraPoiNT conducted by independent bodies. Earlier this year, the Department of Transportation (DOT) evaluated 11 alternate PNT solutions, in which each was rigorously tested across applications and scenarios. As a result of the evaluation, the DOT named TerraPoiNT the best and only performing solution across all PNT categories.

Spartacus. In June, NextNav entered into a definitive merger agreement with Spartacus Acquisition Corporation in a transaction that would result in NextNav being listed on the Nasdaq. The transaction is expected to close late in the third quarter of 2021 or early in the fourth quarter of 2021, subject to satisfaction of customary closing conditions.
