Accurate Indoor Localization through Manifold Optimization
This talk presents the design of a high-accuracy spatial location estimation method using ultrasound waves by exploiting the fixed geometry of the transmitters. Assuming an isosceles triangle antenna configuration, where three antennas are placed as the vertices of an isosceles triangle, the spatial location problem can be formulated as a non-convex optimization problem whose interior …
Unassisted GNSS Attitude Determination: How to Reduce the Time Complexity of the Ambiguity Search in Satellite-Deprived Environments?
Global navigation satellite system (GNSS)-based attitude determination plays a critical role in various navigation, guidance, and control applications. GNSS attitude determination has been applied in various land, airborne, and maritime scenarios. The goal of GNSS attitude determination is to estimate a vehicle’s or platform’s orientation in a reference coordinate system utilizing multiple GNSS antennas/receivers rigidly …
Radio Localization enabled by 5G Technologies and Beyond
Mm-wave and massive MIMO technologies are some of the elements that have enabled the increase of the communication capacity and reliability, and the reduction of the latency in 5G systems. These technologies have also made possible the advent of new positioning solutions characterized by very high accuracy, provision of orientation information, and inclusion of sensing …
Ad Astra: Navigation with Megaconstellation LEO Satellites
We are witnessing a space renaissance. Tens of thousands of broadband low Earth orbit (LEO) satellites are expected to be launched by the end of this decade. These planned megaconstellations of LEO satellites along with existing constellations will shower the Earth with a plethora of signals of opportunity, diverse in frequency and direction. These signals …
Translink Convergence a path to meet 6G’s most aggressive goals
Next-generation mobile and network convergence creates great opportunity and challenge. This talk overviews and suggests translink convergence as a way to leverage O-RAN’s and 3GPP’s significant efforts to date as well as to enable order-of-magnitude improvements in cost, sustainability, latency, and throughputs/coverage. Translink convergence specifically leverages fronthaul split 7.2 in an usual way, using also …
