Positioning technologies and their applications
Positioning technologies like GNSS and visual positioning are complementary and have their strengths and weaknesses. GNSS provides accurate and precise positioning information across wide areas, making it ideal for navigation in open spaces. On the other hand, visual positioning relies on reference maps and databases to provide contextual information in local environments. Wi-Fi positioning and 5G positioning also play a role in terrestrial-based positioning, although they have limitations in terms of precision and accessibility. Overall, a seamless combination of these positioning technologies is the future of ubiquitous positioning.
