Description: 

A GSTP Element 2 activity with France, has taken an existing product used to help signals from satellites reach underground and developed and improved it for navigation purposes.

The product, called SubWave, is for underground geolocation where GNSS signals from satellites cannot be received. It allows the navigation signals to be received with the user’s normal smart phone even underground, for example in metro or road tunnels. But there is currently a drawback, which can lead to significant errors in the position being shown. Now, an improved system called SubWave+, has significantly reduced these errors, developing this system into a marketable product. SubWave+ is a substantial improvement in the system as it brings the accuracy from 10m down to few meters. It extends the location service to cover metro or subway stations and their tunnels, is designed to be compliant with any GNSS receivers and enable a seamless transition between indoor and outdoor. The developed product is already being sold to worldwide customers.
