Autonomous Navigation for the Visually Impaired using a smart connected cane.

<p>Funded by Innovate UK and in partnership with WeWalk Limited, the Royal National Institute for the Blind (RNIB), and Imperial College London, Astraterra developed a new indoor positioning, navigation, and wayfinding system. A project that depicts how technology can serve the visually impaired to gain more independence and autonomy</p>
<p>A key feature of this system is a new empirically derived method based, for the computation of protection level for multi-sensor positioning and navigation incorporating Bluetooth and Inertial Measurement Units (IMUs). Astraterra with Imperial College, together with the Royal National Institute of Blind People (RNIB) developed the cane into a smarter version using GPS sensors, integrity monitoring, and other safety features.&nbsp;</p>

Air Navigation and ATM (Air Traffic Management)

A novel jamming interference detection method based on fractional Fourier transform for Global Navigation Satellite System (GNSS) receivers.

<p>In collaboration with Imperial College London and Hefei University in China, Astraterra developed a novel jamming interference detection method based on fractional Fourier transform for Global Navigation Satellite System (GNSS) receivers.&nbsp;</p>
<p>In this project, several novel optimal fractional order determination approaches of the fractional Fourier transform including First Order Moment of Magnitude and Peak-to-Average Ratio of Magnitude are used respectively in order to reduce the computational complexity of the state-of-the-art generalized time-fractional bandwidth product technique, to accelerate the search procedures to improve search and interference detection efficiency. This resulted in improved search and interference detection efficiency &nbsp;&nbsp;</p>

A comparative study of 14 world cities on Location-Based Services for Bus Operations and their RNP derivation. Challenges and Commonalities.

<p>Undertaken in collaboration with Transport for London (TfL), this project was the first in the world to undertake a detailed analysis of PNT-related applications for ITS for urban bus operations &ndash; having surveyed more than 14 world cities.&nbsp;</p>
<p>This created an exhaustive and comprehensive list of applications together with the corresponding derivation of the required navigation performance in terms of accuracy, integrity, continuity, and availability.&nbsp;</p>
<p>In order to meet the RNP, this project undertook another world first in analysing in detail the impact of the new GPS civil signals in urban environments, with a case study of London. This led to the specification of a PNT system for Urban bus operations that benefit from the strengths of the new civil GPS signals, leading to a significant improvement in location accuracy.</p>
