For analysing performance in alpine ski racing, an accurate estimation of the skier’s centre of mass trajectory and speed is indispensable. However, the sole use of low-cost GNSS might not be accurate enough to detect meaningful differences. The aim of this study was to introduce a new system that can improve the accuracy of a low-cost GNSS to an acceptable level. To this end, the data obtained...

Few decades ago, electronic and sensor technologies are merged into vehicles as the Advanced Driver Assistance System(ADAS). However, sensor-based ADASs have limitations about weather interference and a line-of-sight nature problem. In our project, we investigate a Relative Position based ADAS(RP-ADAS). We divide the RP-ADAS into four main research areas: GNSS, VANET, Security/Privacy, and Appl...

This work investigates the ways that Automatic Gain Control (AGC) operation can be modified to minimise the Signal-to-Noise Ratio (SNR) losses in the presence of a Continuous-Wave (CW) interferer for Global Navigation Satellite System (GNSS) receivers. It was found that the recommendations based on analysis of a probabilistic model of a Direct Sequence Pseudorandom Noise (DSPN) receiver reporte...

Positioning, Navigation, and Timing (PNT) services are the key basis for the provision of both essential (safety and security) and economically beneficial applications worldwide in the 21 century. Whether users are groundbased or sea-based or in the air, their primary/go to source of P and N and T is a Global Navigation Satellites System (GNSS). While the transition of various users/modes of tr...

This paper discusses the development of a Matlab-based multi-Global Navigation Satellite System (GNSS) software receiver. Compared to a real-time GNSS receiver, the major difference is in the implementation mechanism of latching and processing the measurements between the receiver channels of a satellite system as well as channels of different systems. Implementation challenges increase due to ...

This paper studies the benefits of integrating proprioceptive measurements and a-priory geographical knowledge in the GNSS computation to increase availability and accuracy for modern ITS applications. A tightly-coupled framework for merging GNSS pseudo-ranges and odometric measurements is first introduced. An efficient way to merge a 2D navigable roadmap is then presented, including the road s...
