ION GNSS+ 2013

Rx Networks Inc., a leading mobile location technology and services company, today announced a new z-axis determination capability called Zed™. This new solution, comprised of a client software library and associated cloud-based data services, is targeted at chipset vendors, device OEMs and application developers seeking to integrate reliable floor level detection.

Whether for emergency or consumer applications, the determination of a mobile device’s vertical position while indoors presents unique challenges. Given the environment, even when a GNSS receiver attains a fix, a mobile device cannot reliably use the reported altitude. Beacon-based techniques, such as those derived from Wi-Fi or Bluetooth, remain challenging as they often rely on GNSS-based crowdsourcing or costly venue characterization. The built-in barometric pressure sensors in recent smartphones today bring a new ability to estimate altitude; however, each have unique and variable characteristics which prevent floor-level accuracy without further assistance.

Rx Networks’ new Zed™ solution combines accurate geo-reference barometric pressure data (from Custom Weather, a global provider of real-time weather information), automatic device characterization, and pressure crowdsourcing along with existing location services to determine a device’s altitude within 1 to 3 meters.

The Zed™ solution will be commercially available at the start of 2014 and will be available either on its own, or as an optional feature alongside Rx Networks’ GPStream™ Assisted-GNSS and XYBRID™ hybrid location solutions.

For more information a demonstration of Zed™, please see the Rx Networks booth at ION GNSS+ 2013 or contact Rx Networks at sales(at)rxnetworks(dot)com.
