Cohda Wireless beats GPS blackspots in New York City

Australian-based global leader in connected vehicle technology Cohda Wireless has overcome GPS blackspots on the streets of New York City with its breakthrough V2X-Locate vehicle positioning system.

While Global Positioning System (GPS) navigation systems have revolutionised transport, their accuracy degrades in locations with compromised sky views such as 'urban canyons' formed by high-rise buildings, underground carparks and tunnels.

Using its expertise in developing collision avoidance systems for mines, Cohda Wireless designed V2X-Locate to overcome these GPS and Global Navigation Satellite System (GNSS) blackspots.

With offices in Australia, the US, Europe and China, Cohda Wireless software systems provide the complete V2X solution for connected vehicles, smart city deployments, mining operations, and the connected autonomous vehicle (CAV) market, globally.

In late 2017, Cohda Wireless went to New York City to test V2X-Locate against a state-of-the-art GNSS module. For the trial, a vehicle equipped with both V2X-Locate and GNSS was driven down the third lane of Sixth Avenue, which is surrounded by the city's tallest buildings.

Within this environment, GNSS performance was significantly challenged. It was off-course by as far as tens of metres and showed the car driving through buildings. In comparison, Cohda's V2X-Locate system was able to achieve sub-metre accuracy using existing communications signals provided by V2X Roadside Units – typical of smart city infrastructure.

'By eliminating GPS blackspots from city centres, where they are most common, V2X-Locate delivers uninterrupted positioning data for both existing connected vehicles and future driverless cars,' says Cohda Wireless Chief Technology Officer Paul Alexander.

Answering strong international interest, Cohda Wireless has released a V2X-Locate Evaluation Kit containing four Roadside Unit devices to put the system through its paces.
