Title:
POSITION ESTIMATING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2005/114105
Kind Code:
A1
Abstract:
When a receiver (1) can capture a satellite, an information acquiring/storing section (3) in a position estimating system acquires a current position from the receiver (1) and output values from pressure sensors (2R, 2L), and then stores at least the moving speed and direction of a user and the acquired output values. When the receiver (1) can not capture a satellite, a locator (4) takes out the moving speed and direction of the user from the information acquiring/storing section (3) based on the output values acquired from the sensors (2R, 2L) and the output values stored in the information acquiring/storing section (3). Subsequently, the locator (4) estimates the current position of the user based on the moving speed and direction thus taken out.
