Abstract

Positional information for a mobile station is acquired using a data code label and the positional information is updated as the mobile station moves without the need for signals from a Satellite Positioning System (SPS), such as the Global Positioning System (GPS). The data code label is read and information encoded within the data code label is used to obtain positional information, which may be, e.g., a digital map, directions, or non-navigational information, which may be provided via a display or speakers. The positional information may be referenced to a local coordinate system or a global coordinate system. The position of the mobile station is updated using inertial sensors within the mobile station and/or using a measured radio signal and a wireless access point almanac that may be obtained using the information encoded within the data code label. Updated positional information for the mobile station is then provided.
