“The infrastructure can now combine a number of wi-fi hotspots across the establishment, and the GNSS receivers installed on the lab, and can further add users and sensors, both fixed and moving through the complex, to collect and exchange data such as smartphone measurements or cellular radio samples. So that’s quite a lot of data to work with. We’ve been using HANSEL to look into topics such as augmented ‘GNSS +’, Wi-Fi and GNSS+, cellular ‘hybridisation’ and seamless indoor-outdoor positioning, collaborative positioning, as well as snapshot processing.

“Effectively HANSEL has become a new element of ESTEC’s infrastructure, that all kinds of projects are free to make use of.”
