Meet us at the ENC 2017!

Silvia Pichler, 

The 25th annual European Navigation Conference will be held in Lausanne, Switzerland and is organised by the Swiss Institute of Navigation, ION-CH. Navigation tech providers, researchers and the makers and shakers of the industry will be there to introduce their solution innovations and discuss their latest research findings.

Navigation anywhere, at any time, for any purpose.

That’s the motto the conference will revolve around, covering topics such as GNSS, maritime and air navigation, transport as well as urban and indoor navigation.

The agenda is filled with exciting keynotes and presentations, among them two of our senior researchers, Boxian Dong and Reinhard Müllner, renowned for their expertise in Indoor Positioning and SLAM (Simultaneous Localization and Mapping). Calibre

Boxian Dong is going to present “ Calibre – Unsupervised Database Free RSSI Calibration Indoor Navigation” during session D2 on Thursday, May 11th.

The “Calibre” is one of the most important components of the indoors SLAM Crowd Engine. It calibrates the radio sensors on the smartphone so the sensor will have the same RSSI (Received Signal Strength Indicator) readings for the same radio power level. This allows for the creation and updates of radio maps through crowd-sourced data.

In order to avoid the creation and maintenance of a database of calibrated devices, the Calibre  doesn’t require any infrastructure or special data, and standardizes each recorded dataset on the fly. Moreover, any potentially occurring errors won’t have big impacts on the final radio map.

Reinhard Müllner will present his work on “NetFLIPs – A cost effective, scalable and accurate indoor LBS framework using FLIP (Flexible Indoor Positioning estimator)” in session F1 on Friday, May 12th, starting at 10:30AM.

NetFLIPs is a cost-effective, scalable and accurate indoor LBS framework, allowing for simultaneous asset tracking and user positioning, using the same infrastructure. Existing tools like the SLAM Engine enable fast radiomap acquisition. The same single radiomap is used for both use cases – asset tracking and positioning with our location estimator called “FLIP”.

If you’d like to dive deeper into the world of NetFLIPs and Calibre, you should definitely come and get first-hand information from our experts!
