Home Market Cohda claims ‘world-first’ system to beat GPS blackspots

Australian connected autonomous vehicle technology company Cohda Wireless has released a claimed world-first vehicle positioning system that it says eliminates GPS blackspots that exist in so-called “urban canyons” between high-rise buildings.

Cohda says the vehicle-based V2X-Locate system uses its expertise in developing collision avoidance systems for mines, and can identify vehicle position to sub-metre accuracy in environments that degrade GPS accuracy, such as tunnels, underground carparks and between high-rise buildings.

And, according to Cohda, as well as enhancing current connected vehicles, V2X-Locate delivers a critical component for connected autonomous vehicles, which will require uninterrupted positioning data to safely navigate on roads.

The Adelaide-based company says that although GPS navigation systems have revolutionised transport during the past decade, they can suffer from degraded accuracy in locations with compromised sky views.

Cohda says it has designed V2X-Locate to enable equipped vehicles to identify their location using existing Smart City V2X (vehicle-to-everything) roadside infrastructure from any standards-based manufacturer.

Cohda Wireless chief technology officer Paul Alexander said V2X-Locate was a “globally unique product”.

“We solve the problem caused by GPS and satellite-based positioning systems not working in all use-cases.

“If you're in a major downtown area with tall buildings, or in a tunnel or in an underground parking lot, a GPS system can fail, preventing it from delivering accurate results. As well as being inconvenient for current drivers, this is not an option as we enter the era of driverless cars.

“The V2X-Locate breakthrough is to position the vehicle with sub-metre accuracy by using the existing communications signals produced by V2X Smart City infrastructure deployments. The result is that V2X-Locate can eliminate positioning ‘blackspots’ in city centres where they are most likely to occur.”

Both Cohda’s standard V2X Onboard Units and Roadside Units utilise the NXP RoadLINK chipset, which supports V2X-Locate’s highly accurate performance by delivering what Cohda says is best-in-class multi-path channel tracking.

Alexander says that after a pre-release international roadshow in October last year, Cohda Wireless received strong interest in V2X-Locate from both Smart Cities and Tier 1 automotive manufacturers.

And, Cohda Wireless says that to meet demand it has released a V2X-Locate Evaluation Kit, which contains the system and four roadside unit devices, which equips prospective customers to put V2X-Locate through its paces.
