BANSHEE: Hybridization of E-GNSS and WiFi ranging for LBS and automotive Accurate Navigation in Smart city
BANSHEE: Hybridization of E-GNSS and WiFi ranging for LBS and automotive Accurate Navigation in Smart city (2021 – 2022). GSA/GRANT/04/2019. Research on WiFi location through RTT. Coordinator of the Work Package 4: “WP4: Tests&Validation”. Ongoing.
Motivation
BANSHEE (Wifi Assisted Accurate Navigation for Smart Cities) answers to GSA’s Call for Proposals GSA/GRANT/04/2019 - Filling the gaps and emerging E-GNSS receiver technologies and intends to demonstrate a new positioning technology that enhances navigation in urban environments, enables accurate seamless indoor-outdoor and provides scalable navigation solution.
The automation revolution that is transforming our cities requires precise and robust navigation in urban environments, where a degradation of GNSS performance occurs due to multipath and lower satellite visibility, among other factors. Aspects such as multi-constellation or use wider bandwidth signals like the Galileo E5a/b palliate those factors. However, there is still a technological gap to be filled in order to guarantee accurate, robust and reliable navigation in urban and indoor environments. BANSHEE will address this challenge by designing and implementing an innovative solution that combines GNSS and WiFi ranging targeting a seamless indoor/outdoor meter level accuracy.

|
BANSHEE will use WiFi ranging based on Time-of-arrival (the new 802.11mc protocol), not the less accurate Received Signal Strength or Fingerprinting, being used nowadays |
The scope of work of BANSHEE has a clear market orientation and intends to develop an end-to-end operational solution that will be demonstrated for two relevant verticals:
● Automotive: Autonomous driving has pulled the demand of precise and robust navigation in the automotive vertical, which is one of the biggest applications requiring navigation in Smart Cities, where GNSS is most vulnerable.
● Location Based Services or Smartphones: This is clearly the market segment defining the future of GNSS business, with a massive base of GNSS devices.
Description
The scalability of the technology is fostered by the fact that the supporting technologies (GNSS and WiFi) have already a massive presence in the market. This aspect, combined with their affordability, are key factors for the commercial uptake of the technology. Major stakeholders such as Android are clearly betting for WiFi 802.11mc Time-of-Arrival (ToA, commonly referred to as Round Travel Time or RTT) and it is pretty clear that this is going to be mainstream in the coming years. Since RTT is a peer-to-peer technology (rather than point-to-multipoint such as GNSS), there are some potential limitations in the scalability that will be assessed within BANSHEE in order to propose measures to minimize these limitations.
The consortium behind BANSHEE has all the needed competences and stakeholders to cover the entire navigation value chain and to bring the proposed technology as close to market as possible by the end of the project.
In summary, BANSHEE will pioneer an operational solution addressed to Smart Cities leveraging on the combination of GNSS and WiFi ranging technologies to fill the gaps of GNSS in urban and indoor environments for the relevant market verticals of automotive and LBS.
