Seeing and Inertial Integrating Is Believing: Multi-Antenna Vision-and-Inertial-Aided CDGNSS for Micro Aerial Vehicle Pose Estimation

Multi-antenna carrier-phase differential GNSS (CDGNSS)-based pose (position and orientation) estimation aided by monocular visual measurements and a smartphone-grade inertial sensor form the core of a system designed for micro aerial vehicles. It can be applied generally for low-cost, lightweight, high-accuracy, geo-referenced pose estimation.

Link-Layer Coding: A Way to Speed-Up Nex-Gen GNSS

A new approach to facilitate fast and/or reliable reception and decoding of the navigation message in harsh radio propagation conditions derives from digital communications. Link-layer coding (LLC) techniques improve times-to-first-fix (TTFFs) over legacy carousel transmissions and achieve near-optimal performance with a limited complexity increase.

Carpe Signum: Seize the Signal

Innovative features of cellular fifth-generation (5G) signals enable the wireless system to play a major role in autonomous technologies. Test results of a ground vehicle navigating with signals from five 5G base stations (gNBs) over a trajectory of 773 m traversed in 110 seconds show a position root mean-squared error of 4.1 m.
