Accurate indoor localization can save lives with barometric pressure sensors

Описание: Invited talk at Semicon Taiwan on September 2020
In the last few years, there has been an explosion of user cases involving the location of consumer electronics devices such as smartphones, tablets and wearable devices. This need for positioning and navigation has extended from outdoors where GNSS provides high quality service to indoor areas where it is inadequate. Dr. Thomas Block will present an update on the progress that barometric, MEMS-based navigation has made in augmenting our everyday lives, from the extension of the battery life in a GNSS-enabled smartwatch, to vertical location inside buildings (e911 as mandated by the FCC). The addition of the vertical-specific position to existing horizontal information enables first responders to determine the floor level of smartphone users who trigger an emergency call. The Federal Communications Commission (FCC) estimates that the additional vertical information has the potential to save up to 10,000 lives per year just in the USA alone. Real world examples are presented for the full range of commercially available Environmental MEMS components including air pressure sensors as well as their interaction with wide area infrastructure, advanced navigation software and positioning ecosystems. BMP390 as High-Performance barometric pressure sensor is presented as well.
