Abstract
An inertial navigation device for fitting to an article that bears intermittently against a surface. The device comprises an inertial unit having at least one inertial sensor, and a mechanical connector structure for connecting the inertial unit to the article. In the device, the connector structure is arranged (1) to provide mechanical coupling between the inertial unit and the article when the article is not bearing against the surface and (2) to provide mechanical decoupling therebetween when the article is bearing against the surface, in such a manner that the inertial unit is substantially stationary relative to the surface when the article is bearing against the surface. A shoe and equipment is provided with such a device.
