ABSTRACT
Today's GPS navigators have difficulty determining altitude such as whether a car is under or on an overpass. In this paper, we show how to use the barometers, which come with off-the-shelf smartphones, to improve vertical positioning accuracy. We will present performance testing results from different real road scenarios to show the feasibility of the proposed method.

Monitoring building door events using barometer sensor in smartphones
UbiComp '15: Proceedings of the 2015 ACM International Joint Conference on Pervasive and Ubiquitous ComputingBuilding security systems are commonly deployed to detect intrusion and burglary in home and business structures. Such systems can accurately detect door open/close events, but their high-cost of installation and maintenance makes them unsuitable for ...
Using mobile phone barometer for low-power transportation context detection
SenSys '14: Proceedings of the 12th ACM Conference on Embedded Network Sensor SystemsAccelerometer is the predominant sensor used for low-power context detection on smartphones. Although low-power, accelerometer is orientation and position-dependent, requires a high sampling rate, and subsequently complex processing and training to ...
Vehicle State Estimation System Aided by Inertial Sensors in GPS Navigation
ICECE '10: Proceedings of the 2010 International Conference on Electrical and Control EngineeringDespite the development of the GPS navigation system, problems still lies in two topics: GPS signal losses and unreliable positioning in the elevation direction. This paper proposes a vehicle state estimation system to produce integrate information ...
